My father worked of Besler Corporation as a machinist in the SF Bay Area before WWII. Then he was drafted into the US Army during the war. Upon returning from the war, he walked right back to his machinist station at Besler like he had never left. Later he was promoted to being a field rep for Besler's agricultural sprayers throughout California. I had heard about the steam plane a short time ago from my sister. Thanks for presenting this video.
Well your memory is shot. It was in Emeryville, CA., parallel to to the railroad junction, a block away from a foundry and three blocks away from another foundry. Absent from this video was that this flight happened in Oakland Airport’s North Field, the same place where both Lt. Hegenburger made the first trans-Pacific flight, and also Amelia Earhart. William and George Besler were both Geniuses.
@@estebancorral5151 Pardon, but who are you talking to, me? Emeryville is certainly in the SF Bay Area, which is close enough for TH-cam. My dad worked for Bill Besler just as I described until 1956, and flew in Besler's Beechcraft Bonanza many times for business purposes. Besler also invited my mother and very young brother and sister on at least one flight. I have the black and white picture of my siblings standing in front of the airplane. What part of my memory is "shot"? I was not even born until 1961. By then my parents had long moved on and started their own business.
Water consumption has always been the bane of compact steam propulsion. Condensers are heavy, and despite many claims, no one has ever come close to making an effective one small enough to be practical in a car, plane, or similar. Bill Lear's fictitious steam car is another example.
You might want to look into steam cars more. There were plenty of steam cars up untill the 1920's, and as far as I know, none of them had any problems with condencing the water. The biggest problem steam cars had was that starting them up was tidious work and took a long time. Even before the starter engine, internal combustion engines only took a minute or a few to get running. The Doble E20 steam car from the 1920's was the most advanced steam car ever, and I've heard it was pretty much the only practical steam car in the sense that lighting up the boiler was easy and it only took a few minutes to generate enough steam to get it running. You should take a look at the episode of Jay Leno's Garage with the Doble E20 in it, very informative and interesting.
Replacing water with mercury might turn out to be interesting. The boiling point is well below melting point of aluminium, boiler would not be a problem. Turpentine would be another fun thing to try
@@paistinlasta1805 quite intimately aware of the history of steam propulsion, in automobiles in particular. The models without condensers were limited in range and usefulness by the amount of water they had the means to carry, and similarly those with condensers used so much of their considerable size and weight for the operating mechanism that, as cars became practical parts of everyday life instead of 2 seat go carts for the rich, they quickly gave way to fat more efficient gasoline designs, just like the early electric models.
Ed, I’ve said something like this before on another of your videos, but it’s worth repeating (and I hope you manage to read this). I’ve been avidly interested (and I mean nerd level) in aviation and its history for as long as I can remember (which is close to 50 years now, but I expect my memory will soon become the limiting factor in this statement). I have a doctorate in aeronautical engineering, I work in the industry have a bookcase full of Putnam books and yet your videos always seem to manage to find subjects I’ve either never heard of, or alternatively give an angle that avoids the easy narrative of an aircraft and forces us to think. I don’t know how you do that part, but to achieve that and add to it your self deprecating humour as additional icing means that your videos float to the top of my pile of favourite TH-cam content. Honestly really well done and keep it up. You bring light into the life of at least one person. High praise I know.
What killed off the steam car(and the electric car) wasn't the internal combustion engine itself but the electric starter motor as all the benefits of Internal combustion is for naught if the bloody thing will try to break your arm every time you try to start it.
With my first car I had, on occasion, to start it by hand. Not a fun thing to do at the best of times. On a cold wet and windy night it's surprising how many swear words you remember.
Not entirely true. Power density is what caused IC engines to replace steam the second they were usable for small vehicles, hand start and all. Big things like trains just took a bit longer for the technology to scale up.
There were several issues. Perhaps the largest was thermal efficiency. A pound of steam at atmospheric pressure and 212 degrees F contains about 970 BTU of latent heat that was absorbed in boiling the water. This energy can't be used to perform work in the engine and is discarded to the atmosphere either by exhausting the steam or via a condenser. Then there's the issue of contaminated feedwater causing accumulations on boiler inner surfaces that lead to burnout. We also have complexity as you need a boiler, feed pump, and boiler controls in addition to an engine.
@@bigblue6917In the late 70s a med student I roomed with owned a Hillman Minx that had optional crank start. I think it was about a 1963 model or so. Very useful for doing tune-ups,he did almost all the service and maintenance himself.
Hiram Maxim supposedly managed to get a steam power plane airborne a decade or so before the Wright brothers. But as the plane was bolted to a set of railway tracks and pulled the track up with it before crashing, it doesn't count as the first successful flight. (The whole contraption was an engineering test-bed and not an actual airplane prototype so it was never intended to fly in the first place.)
Well call me 'Captain Pedantic' (please - I crave recognition) BUT That is not multiple questions, it is a single observation or comment Questions are things like 'Why is a mouse if it spins?' & 'Where was Ed when the light went out?'
There is a Jay Lenno episode with a magnificent Doble E-20 silently crousing at 65 mph. Fully reusing the water after a condenser, all controled by quarz crystal.
If the steam plane concept could have been refined more it would have made a great carrier borne recon aircraft with seemingly no need for arrester hooks.
@mpetersen6 Kind of. Steam Traction was more of a combo of relative manpower & speed of availability issues. (it took much longer & more people to cold start a Steam Locomotive than a D/E or D/H... though electric preheaters did reduce this gap a fair bit) In reliability the Steamies had a clear advantage, taking much more abuse for them to break down than contemporary Diesel-Electric's, and being far more effective in extremes of weather.
There was a fairly serious attempt to develop a steam turbine powered aeroplane - the Bristol Tramp - in the immediate post WWI period, though ultimately it did not get built. The logic there was that it was to carry mail from ocean liners, and that the crews of ocean liners were already very familiar with steam turbines but not internal combustion engines.
Was surprised you didn't mention Sir Hiram Maxim's steam-powered flying machine in the intro. And lest we forget, NASA's steam powered [Stirling cycle] airplane is legendary among the EAA crowd. As always, very interesting & highly entertaining. Thank you for your content!
One of your shorter videos but, definitely 1 of your better ones. It's fascinating and I never would have thought in a million years that people would have tried to use a steam engine to power an airplane but apparently they did and they had some modicum of success. Again fascinating, thank you.
In 1972, living in Los Angeles and going to UCLA, I was involved with a number of young engineers to saw modern steam power as a viable alternative to "internal explosion engines" (this from the Stanley catalog) and Los Angeles air pollution. We also researched the technologies of the 1920s and 30s, especially the Doble steam car. I also belonged to the Steam Automobile Club of America, composed of both Young Turks like me and old-timers. I attended a conference in Oakland. Two of the steam aficionados were remarking that "Barney Becker might bring 'Betsy'" to the event. We were in front of the hotel meeting room when we suddenly felt, but didn't hear, a vehicle approaching. Becker had worked for Besler and had restored and tended to a 1925 maroon convertible, probably the one in the old movie shown. We got to crawl all over and under the car, and he took several of us for rides. No mechanical noise, just the growling from the tires. So, I am proud to say that I rode in a 1925 Doble.
It doesn't surprise this Iowa boy! There were even plans in a book called The Boy Mechanic for steam powered model airplane engines before this airplane took flight. Hanging from the ceiling in the airplane museum in Oshkosh Wisconsin are a few models with tiny steam engines and flash boilers. If you want to see something really impressive look up steam powered model boat racing. They race these models on water in a circle using a tethered line. These model boats have tiny steam engines with flash boilers. They are a blur as they zip around in a circle.
@@waynethomas3638 Yes those are considered steam powered but until you watch one of those flash boiler racers on TH-cam you have no idea how high the bar has been raised! One of the videos is titled Flash Steam Hydroplane 2
Jay leno has some great videos explaining the steam cars, The Doble, White and Stanley Steamer were all pretty cool and he still drives them today. Never knew they made a plane with a steam engine in it, makes sense though at the time those Steam cars were better than the gasoline powered ones which might seem strange today.
The Doble engine is a wonderful piece of engineering, difficult to copy even with modern materials. All power to Jay Leno for his preservation of running examples.
The thought never crossed my mind to power a plane using steam, because, we'll, it's crazy. But seeing somebody actually got it to work is incredible. Thank you for making video. You've captured my attention. What other videos have u got? Damn it! Another rabbit hole. Ya Bastard!
You pointed out that the Bessler had a condenser, which would make it a closed-loop cycle as opposed to steam locomotives that had to periodically refill their water tanks (some engineers did try to place condensers in steam locomotives but that didn't work well). I'm a bit fascinated by steam, having served in three Navy ships that were steam-powered. Maybe this push to make electric planes will prove infeasible when we start using up all our lithium and eventually run out. Steam is nice because, like a gas turbine, it can run quite well on a variety of fuels.
South Africa rail had a long run over basically desert. They used steam engines with condensers quite successfully for many years. Admittedly that is the only case I know of that had a practical result.
Its not that it wouldn't be practical as such, it's just extra effort, in maintanance especially. The dobbles also ran on kerosine with a boiler, while coal trains get a draft and power benefit from expunging to air(more power). Anyway lenos channel has bunch of vids on rebuilding dobbles
The moment you mentioned the steam generator came from the Doble auto company I knew how well suited the engine would actually be. Those things weren't just boilers, they were remarkably efficient steam generators. Jay Leno has a great video about the Doble E-20, one of the fastest production cars in the world when it was made in 1925. It still runs, still easily overtakes modern cars on the highway, even beats California emissions standards unmodified!
Wow!!! Never imagined steam, could be applied, for flight🤔!!! And talk about, thrust reversers………. The motor in reverse?!! Good short doc, on something, not heard about.
I found this aircraft when researching for a fantasy story, it's fascinating to think what aircraft would have looked like if the combustion engine was never invented, and the Besler Steam Plane is certainly living proof that they wouldn't have been too difficult or farfetched at all
The instant reverse on a propeller would be very useful on a Swamp boat, which also use aero engines and propellors. And no shortage of resupply water skimming over the top of a swamp in a flat bottomed boat.
swamp water, while surprisingly good due to the presence of all the tannins in it, is an awful water source. The purer the water, the better a boiler will behave. It would make sense to do as large steam ships do. Just use the swamy as a heat sink for a condenser and recycle the pure steam boiler water.
The problem for this applicatoion is that small steam engines are very heavy for theyr power output. They work well in the power range of a train, but on the low end the size becomes unsuitable. Big ships used this reverse ability , but it was less than instantantaneous, took some more time to stop and reverse because of inercia, like you can see in that engine scene of "Titanic". All pressure powered motors can do that, be it steam, air or hidraulic pressure.
That is a great idea. The condenser could be built into the hull and cooled by the swamp water, and low noise would be a huge benefit in boating. Such a craft could use a number of carbon neutral fuels including ethanol and charcoal to produce steam, and the engine would be virtually maintenance free.
@@davepennington3573 Yeah, and doubly so, because in a swamp boat, you have no brakes... so with a suddenly reversible engine, you now can now throw it in full reverse and brake like a mofo, then throw it back into full foward. Turn on a dime. I dare say, I could do some wild boating "aero / acro batics" with a lightswamp boat with a reversible engine on it and all the wild waves I was chopping up playing in place. Jetski style fun.
When fuel was running out you needed to fly quite low so your copilot could pick branches from the trees for fire wood, but you got plenty of water with that condenser when you flew through clouds.
Steam powered flying machines area a lot more common than people realize. It's a real "rabbit hole" topic, and there are documented cases of steam aircraft flying long before the Wright brothers. Great Video as always Ed.
Wasn't there an Italian who built a steam powered floatplane back in the 1880s I think. He tried it out on a lake and claimed it did briefly fly though there were no witnesses
I read about this in a 1970s(?) EAA magazine. I believe it was fueled by parafin/kerosene. Flash boiler, & condenser would be a closed loop, so I wonder why 15min duration? Clearly, there was a loss of steam, watching the film, but that couldve been rectified. The written article stated the engine was used in railway shunting locos. A Traveair 2000 would be lovely, but with steam propulsion even nicer, although I do like the OX5, with that tube& enc rod operating the valve gear. Good video, thank you
This is a completely insane craft, I had never heard of a successful steam application in aircraft. Someone today should be able to come up with a solution for the water issue by capturing the exhaust steam pass it through a condenser and cool it back into water.
The Dobble cars had better boiler and condenser than other makes of steam cars. The problem is too much weight for the aeroplane, I suppose that's a shame. I believe the big issue that stops some of those steam cars going within a minute or two is that the whole engine must be hot enough so that the steam does not condense because water won't compress but will damage the engine. Having said that, some much lower speed cars not 120MPH Dobble do start in 90 seconds.
Maybe they thought they could in time iron out the problems, An intersting idea though to carry enough water fuel etc would take up alot of room as well. Great find Ed love your channels finds on odd one outs.
Thanks for a very interesting video. The DFW Floh 248 aircraft would have been a good candidate for the steam powered aero-engine. Plenty of fuselage volume for water, condensers, fuel, etc.
From what little I've read about the Besler, their experiment showed that steam power production dropped as altitude increased due to the effects of colder air on the boiler, condenser, and "fuel".
FWIW: Back in the late 80s or early 90s I saw a presentation by an FAA rep about Aviation. Much of the presentation, what I remember of it anyway, dealt with the classification change to Class A, B, C, etc. Airspace. One other thing he mentioned {which I unfortunately DID NOT ask about AFTER the presentation} was the concept of steam power for modern General Aviation aircraft. He mentioned a system using a steam turbine and operating at several hundred PSI, or maybe even over 1,000 PSI. The system would use a VERY SMALL boiler -- possibly around the _size_ of a disposable propane cylinder -- to make boiler failure not totally catastrophic. Whether this was all just _conjecture_ or had actually been researched to some extent I do not know.
The first powered flight (In June 1848, was achieved by inventor John Stringfellow in Chard Somerset, by his unmanned aircraft which was powered by a tiny steam engine. Not many people know that,ma bit like the first World Land Speed Record was made by an electric car.
The aircraft may be called a Besler, I'm calling it a Doble for the purposes of the mechanicals. Basics of "Doble" as a company, like the Three Stooges, comprising of a rotating cast of brothers, with Abner being the eccentric genius, sadly they were better engineers than businessmen... they developed their models A through K (except I). This is complicated by the models A, B and G being built as "Detroit", and models A through F being cars, with G through K as larger designs. Models C through F were developments upon each other, with the letter generally designating a major alteration in design. The model E was seen as the peak in user-friendliness, fast in starting (minutes from cold to "usable" - enough to move at a dawdle) and on road, it did condense it's water with a 35% loss rate (most other condensing had a rate closer to 50%). The illusive Model F is also the last E chassis - defined as F due to it's significant differences to the majority of E's. The Model G and H were used in Buses, so were considerably larger... the Model J was used by Sentinel Waggons of Shrewsbury as a basis for their Columbian Locomotive.
Heard of a Russian pioneer, ~1880, who tried a flight in a craft powered by 2 steam engines, but stalled (?) after liftoff & was crushed betwixt the 2 engines, so close 2 being the 1st 2 fly successfully. Wish i knew more...
I heard of that too. If I am not misremembering, he tried to test his plane jumping off a bridge. And he used small locomotive engines. Literally a flying train...
@@carloshenriquezimmer7543 Not really a flight then. Turns out the secret to being the first to powered flight was figuring out that propellers need to be airfoils, and spending a LOT of wind tunnel time figuring out an effective design. The Wright brothers broke that code while everybody else was trying to use paddles.
A more extreme example of this would be one of the proposed Me 264 variants that tried extremely hard to turn the whole plane into a flying boiler... and while the steam plane itself never got built, (I think) the company tasked to build the whole system did finish it.
When (or if) you have no oil, these will be common. Like private cars in occupied Europe during WW2 using things like coal gas and steam. Don't do a loop though! Thanks for a very interesting plane and powerplant video.
Too bad that isn't recreated with modern materials and powerplants. His propellers are so inefficient for the rpm and torque put on them and the frame. That thing was weird looking but I see possibilities. That would be fun.
VERY steampunk airplane, something straight out of a novel! imagine if combustion engines neevr took off and instead steam engines got improved to that point, i can already imagine all sorts of things out of this!
Are there advances in Steam boilers and condensers allowing a remake of Besler steamer airplane engine? External Combustion Engines, Steam machines and the heavier as a brick Stirling, could work on everything that burns. With AvGas about to be banned in places as California-A, always expensive and hard to find in many countries, Aircraft Steam machines are not that krazee now. What happened to the German research on Aircraft Steam Turbines? This sounds as a perfect companion to the Nuclear Reactor tested inside a B-36. Blessings +
There was also a military project in the 1950/60ies on steam powered helicopters. A single seater named "Dragon Fly" and a double seater named "Atlas" were built und tested. The last presentation of them was at the Farnborough Air Show in 1998. But these helicopters had a very special steam generator, which uses 95% hydrogenperoxide and a silver catalyst and a very light weight engine. Today the use of such high percentage hydrogen peroxide is forbidden, because it could become very dangerous. Such steam generators were also used to operate rocket belts and jet packs.
The first aircraft to successfully take off and fly under steam power was Hiram Maxim's test bed vehicle in about 1884. As it was never actually intended to fly, just test the concept, it had no control surfaces. So, it was not counted as a controlled filght
You could spin an absolutely ludicrously big propeller with one of those. In fact, you could probably spin the whole aircraft like it's nothing, lol. I don't know if I like the idea of a fire being on the plane at all times, specifically, an exposed flame.
When I was a kid in the 1950, the Bessler was never mentioned the idea of a steam-plane seemingly dying with Hiram Maxim's failed attempt supposedly over-shadowed by the Wright Brothers and their internal-comustion engine. The history books really need to be re-written!
I worked with Bessler's grand daughter about 15 years ago. She told some cool stories about him. Her parents have some of his drawings of engines and stuff.
I have interviewed as many people as I can find because I plan on writing a book on him. Can you send me contact information for the grandaughter? I was told that the daughter was only interested in horses and did not save any of Besler's steam stuff. Tom Kimmel
@@tomkimmel8726 I will see what I can do and pass on the info to her. The comment about the horses made me LOL because she is (was?) a barrel racer and a horsey person 100%! I got the feeling that she did not realize the impact her grand father made on the world we live in. I might be wrong about that, but that's the feeling I got at the time.
Steam engine for aviation 🤔. I've heard of a worst idea how about a plane with an atomic reactor! What could possibly go wrong? Thanks for another excellent video.
I just love people who have to try 😅 even if it will never be, you learn from it. Fx) You do not have to cranke the engine, it starts when the steam is on. ) You can reverse the engine, stopping fast. ) You can speake to the person beside you. ) Sems you could speak (loud) to people on the ground. And ofcorse today we are getting moore and moore experiment with electric propulsion, who have some similarity with steam dito.
It is said that 747s had steam assisted take-offs. They had to pump cooling water into the engine - obviously this turned into superheated steam, producing increased thrust.
I never heard of any 747 with water-injection. The early models of B-52 and KC-135 used water injection at takeoff to support getting a greater payload into the air. The water tanks would be close to empty by the time they reached a good altitude.
@@stoobydootoo4098 I believe with water injection (and the related methmix) the additional thrust comes from an increase in the engine’s mass flow rate due to the enthalpy change of liquid water to steam. So you’re right that the water acts as a coolant, but its purpose was to cool the air (not to benefit or cool the engine itself), and by doing so it increase the density (mass) of the working fluid. Change in working fluid momentum = mass x velocity change = thrust.
Interesting. I knew of this aircraft, but not that it used Doble's technology. Perhaps the condenser was a WIP, as it makes no sense to add one if you’re not reusing the water. Certainly not in a plane, where pounds count, not to mention drag.
I'm fairly certain that Henry Maxim, who went on to invent the machine gun, built and flew for a very short distance a steam-powered airplane which he flew in a London park. I can't swear to the date but records definitely exist including a plan of his engine.
The boiling point of water drops with increasing altitude. So a plug in (the kettle element) hybrid steam plane should be able to take of and climb with (close to) zero heating. Once up to cruise altitude, very little extra energy (in the form of a std fuel) required to keep it cruising...
@@SoloRenegade The Tu-95 only carried a reactor aloft to see if it could be operated inflight, the B-36 was testing two different air cycle propulsion systems.
@@luvr381 I say again, "how does a nuclear reactor produce electricity?" How does a nuclear reactor power an airplane? stop avoiding the question and just answer it.
@@SoloRenegade Neither of those engines used electricity to propel themselves. The two broad types of nuclear aircraft propulsion are Direct Air Cycle, where air is ingested into a jet's compressor, then funnelled into the reactor where it is superheated (and the reactor is cooled) and then funnelled back into the engine, into the turbine section and then out the back. This is a turbine engine where the combustion chamber is replaced with a nuclear reactor. The other type is called Indirect Air Cycle, and has a working medium (steam or molten salt) passed through the nuclear reactor then into a heat exchanger inside of the engine. This heat exchanger replaces the combustion chamber in a conventional turbine engine. These approaches work for turboprops and jet aircraft. The B-36 was a piston powered aircraft (primarily), but the experiments in which nuclear reactors were carried by B-36s were only to determine whether the shielding to protect crew and equipment could be carried in an aircraft without compromising safety or payload. There's no need to be so demanding of @luvr381, they'd replied to you once (when I was writing this comment, at least), and all of this information is available online.
@@SoloRenegade likely by doing the same as nuclear power plants do, use nuclear to produce steam and convert the pressure of the steam into electricity. though not much is known of how these test beds worked.
Gyro Gearloose once invented a steam powered piloted rocket 🚀 but it emitted so much smoke that he couldn’t see if he ‘d got airborne or not. & when he did, he lost power so quickly that his craft crashed into City Hall.

A pound of steam at atmospheric pressure and 212 degrees F contains about 970 BTU of latent heat that was absorbed in boiling the water. This energy can't be used to perform work in the engine and is discarded to the atmosphere either by exhausting the steam or via a condenser. Then there's the issue of contaminated feedwater causing accumulations on boiler inner surfaces that lead to burnout. We also have complexity as you need a boiler, feed pump, and boiler controls in addition to an engine.
@@bigblue6917In the late 70s a med student I roomed with owned a Hillman Minx that had optional crank start. I think it was about a 1963 model or so. Very useful for doing tune-ups,he did almost all the service and maintenance himself.
@@joshkamp7499 Plus they needed to discover genetic engineering in order to raise railway engineers big enough to wind the starter handles of course
Hiram Maxim supposedly managed to get a steam power plane airborne a decade or so before the Wright brothers. But as the plane was bolted to a set of railway tracks and pulled the track up with it before crashing, it doesn't count as the first successful flight. (The whole contraption was an engineering test-bed and not an actual airplane prototype so it was never intended to fly in the first place.)
That sounds like a very Hiram Maxim thing to do.
This make's my brain hurt with the number of questions this immediately spawns!!!! Wow just Wow!!!!
Well call me 'Captain Pedantic' (please - I crave recognition) BUT
That is not multiple questions, it is a single observation or comment
Questions are things like 'Why is a mouse if it spins?'
& 'Where was Ed when the light went out?'
One question you have ...must be ....that you get all steamed up about it ......
@@Farweasel yes I know what a question is! It was indeed a comment well noticed....
There is a Jay Lenno episode with a magnificent Doble E-20 silently crousing at 65 mph.
Fully reusing the water after a condenser, all controled by quarz crystal.
If the steam plane concept could have been refined more it would have made a great carrier borne recon aircraft with seemingly no need for arrester hooks.
That was my first thought. What really killed steam in rail applications was excessive servicing requirements compared to diesel and electric types
Reversible pitch props do the same. No need to have a reversible engine.
@mpetersen6 Kind of. Steam Traction was more of a combo of relative manpower & speed of availability issues.
(it took much longer & more people to cold start a Steam Locomotive than a D/E or D/H... though electric preheaters did reduce this gap a fair bit)
In reliability the Steamies had a clear advantage, taking much more abuse for them to break down than contemporary Diesel-Electric's, and being far more effective in extremes of weather.
The fact that it was ultra quiet made it perfect for recon on the battlefield. Weight would not be an issue because it wouldn’t be carrying weapons
Maybe even for a small reconnaissance Helicopter on Submarines
There was a fairly serious attempt to develop a steam turbine powered aeroplane - the Bristol Tramp - in the immediate post WWI period, though ultimately it did not get built. The logic there was that it was to carry mail from ocean liners, and that the crews of ocean liners were already very familiar with steam turbines but not internal combustion engines.
Was surprised you didn't mention Sir Hiram Maxim's steam-powered flying machine in the intro. And lest we forget, NASA's steam powered [Stirling cycle] airplane is legendary among the EAA crowd. As always, very interesting & highly entertaining. Thank you for your content!
One of your shorter videos but, definitely 1 of your better ones. It's fascinating and I never would have thought in a million years that people would have tried to use a steam engine to power an airplane but apparently they did and they had some modicum of success. Again fascinating, thank you.
In 1972, living in Los Angeles and going to UCLA, I was involved with a number of young engineers to saw modern steam power as a viable alternative to "internal explosion engines" (this from the Stanley catalog) and Los Angeles air pollution. We also researched the technologies of the 1920s and 30s, especially the Doble steam car. I also belonged to the Steam Automobile Club of America, composed of both Young Turks like me and old-timers. I attended a conference in Oakland. Two of the steam aficionados were remarking that "Barney Becker might bring 'Betsy'" to the event. We were in front of the hotel meeting room when we suddenly felt, but didn't hear, a vehicle approaching. Becker had worked for Besler and had restored and tended to a 1925 maroon convertible, probably the one in the old movie shown. We got to crawl all over and under the car, and he took several of us for rides. No mechanical noise, just the growling from the tires. So, I am proud to say that I rode in a 1925 Doble.
Crackpots and con men...
It doesn't surprise this Iowa boy! There were even plans in a book called The Boy Mechanic for steam powered model airplane engines before this airplane took flight.
Hanging from the ceiling in the airplane museum in Oshkosh Wisconsin are a few models with tiny steam engines and flash boilers.
If you want to see something really impressive look up steam powered model boat racing.
They race these models on water in a circle using a tethered line. These model boats have tiny steam engines with flash boilers.
They are a blur as they zip around in a circle.
Way cool.
An example would be the putt putt boats powered by a candle!
@@waynethomas3638 Yes those are considered steam powered but until you watch one of those flash boiler racers on TH-cam you have no idea how high the bar has been raised!
One of the videos is titled Flash Steam Hydroplane 2
Finally a solution to keeping warm at high altitudes - use the cockpit as the condenser.
Come the apocalypse this will be pure gold. Water and sticks will never run out
Jay leno has some great videos explaining the steam cars, The Doble, White and Stanley Steamer were all pretty cool and he still drives them today.
Never knew they made a plane with a steam engine in it, makes sense though at the time those Steam cars were better than the gasoline powered ones which might seem strange today.
I was like, hope the engine is something like a Doble!
😂
Excellent examination of an unimaginable curiosity. Love the quirkiness of this machine, and the courage of the brothers to develop it. Thanks, Ed.
Fascinating that the quiet operation of this aircraft was remarked on. I would LOVE to hear a recording of this thing. I wonder if one exists?
i enjoyed jay leno's videos on steam cars a lot. they allow a glimpse into that technology, i recommend.
Jay did great stuff on the cars. Incredible engineering.
The Doble engine is a wonderful piece of engineering, difficult to copy even with modern materials. All power to Jay Leno for his preservation of running examples.
The thought never crossed my mind to power a plane using steam, because, we'll, it's crazy. But seeing somebody actually got it to work is incredible. Thank you for making video.
You've captured my attention. What other videos have u got? Damn it! Another rabbit hole. Ya Bastard!
You pointed out that the Bessler had a condenser, which would make it a closed-loop cycle as opposed to steam locomotives that had to periodically refill their water tanks (some engineers did try to place condensers in steam locomotives but that didn't work well). I'm a bit fascinated by steam, having served in three Navy ships that were steam-powered. Maybe this push to make electric planes will prove infeasible when we start using up all our lithium and eventually run out. Steam is nice because, like a gas turbine, it can run quite well on a variety of fuels.
South Africa rail had a long run over basically desert. They used steam engines with condensers quite successfully for many years. Admittedly that is the only case I know of that had a practical result.
Its not that it wouldn't be practical as such, it's just extra effort, in maintanance especially.
The dobbles also ran on kerosine with a boiler, while coal trains get a draft and power benefit from expunging to air(more power).
Anyway lenos channel has bunch of vids on rebuilding dobbles
The moment you mentioned the steam generator came from the Doble auto company I knew how well suited the engine would actually be. Those things weren't just boilers, they were remarkably efficient steam generators.
Jay Leno has a great video about the Doble E-20, one of the fastest production cars in the world when it was made in 1925. It still runs, still easily overtakes modern cars on the highway, even beats California emissions standards unmodified!
The exhaust port is pointed towards the tail, right? So Bessler was blowing steam out it’s rear…
/badoomtish
Wow!!! Never imagined steam, could be applied, for flight🤔!!! And talk about, thrust reversers………. The motor in reverse?!! Good short doc, on something, not heard about.
Appreciate the shout-out to Drach!
I found this aircraft when researching for a fantasy story,
it's fascinating to think what aircraft would have looked like if the combustion engine was never invented, and the Besler Steam Plane is certainly living proof that they wouldn't have been too difficult or farfetched at all
imagine the night fighters/bombers you could achieve with this technology when developed further...
Steam piston engines are notoriously inefficient, about 8% efficient. That's why they're rare nowadays.
Thank you for another informative video about a plane that I had never heard of before.
I was only half listening when the vid started. But then I heard the 'lay the tracks down' joke and the cymbals. Cracked me up!
The instant reverse on a propeller would be very useful on a Swamp boat, which also use aero engines and propellors.
And no shortage of resupply water skimming over the top of a swamp in a flat bottomed boat.
swamp water, while surprisingly good due to the presence of all the tannins in it, is an awful water source. The purer the water, the better a boiler will behave. It would make sense to do as large steam ships do. Just use the swamy as a heat sink for a condenser and recycle the pure steam boiler water.
The problem for this applicatoion is that small steam engines are very heavy for theyr power output. They work well in the power range of a train, but on the low end the size becomes unsuitable.
Big ships used this reverse ability , but it was less than instantantaneous, took some more time to stop and reverse because of inercia, like you can see in that engine scene of "Titanic". All pressure powered motors can do that, be it steam, air or hidraulic pressure.
That is a great idea. The condenser could be built into the hull and cooled by the swamp water, and low noise would be a huge benefit in boating. Such a craft could use a number of carbon neutral fuels including ethanol and charcoal to produce steam, and the engine would be virtually maintenance free.
@@davepennington3573 Yeah, and doubly so, because in a swamp boat, you have no brakes... so with a suddenly reversible engine, you now can now throw it in full reverse and brake like a mofo, then throw it back into full foward. Turn on a dime. I dare say, I could do some wild boating "aero / acro batics" with a lightswamp boat with a reversible engine on it and all the wild waves I was chopping up playing in place. Jetski style fun.
@@choppergirl With twin fans it would be insane
If this video had been uploaded on April 1st you definitely would have assumed it was an April fools joke.
Well they do say that reality can be and often is way stranger and crazier than fiction 😅
The Bessler brothers were notorious con men... this was a scam from the start, much like the solar powered car start-ups of today
Wait till you see Flash Steam Hydroplanes.
@@lancaster5077 Space X says its mars rocket will be steam powered!
When fuel was running out you needed to fly quite low so your copilot could pick branches from the trees for fire wood, but you got plenty of water with that condenser when you flew through clouds.
Steam powered flying machines area a lot more common than people realize. It's a real "rabbit hole" topic, and there are documented cases of steam aircraft flying long before the Wright brothers. Great Video as always Ed.
Granted it seems like those aircraft, unlike this example, were incapable of being controlled in flight
Wasn't there an Italian who built a steam powered floatplane back in the 1880s I think. He tried it out on a lake and claimed it did briefly fly though there were no witnesses
Wright bros most important invention was the practical actually working 3 axis control of the flight.
Jay Leno sent me here form his latest vid on the "Big Boy"
Me too
Well done, Ed! I have been into old aeroplanes since I was a schoolboy, but have never heard of this.
I read about this in a 1970s(?) EAA magazine. I believe it was fueled by parafin/kerosene. Flash boiler, & condenser would be a closed loop, so I wonder why 15min duration? Clearly, there was a loss of steam, watching the film, but that couldve been rectified. The written article stated the engine was used in railway shunting locos. A Traveair 2000 would be lovely, but with steam propulsion even nicer, although I do like the OX5, with that tube& enc rod operating the valve gear. Good video, thank you
This is a completely insane craft, I had never heard of a successful steam application in aircraft. Someone today should be able to come up with a solution for the water issue by capturing the exhaust steam pass it through a condenser and cool it back into water.
The Dobble cars had better boiler and condenser than other makes of steam cars. The problem is too much weight for the aeroplane, I suppose that's a shame. I believe the big issue that stops some of those steam cars going within a minute or two is that the whole engine must be hot enough so that the steam does not condense because water won't compress but will damage the engine. Having said that, some much lower speed cars not 120MPH Dobble do start in 90 seconds.
Maybe they thought they could in time iron out the problems, An intersting idea though to carry enough water fuel etc would take up alot of room as well. Great find Ed love your channels finds on odd one outs.
Thanks for a very interesting video. The DFW Floh 248 aircraft would have been a good candidate for the steam powered aero-engine. Plenty of fuselage volume for water, condensers, fuel, etc.
I wonder could they have used the used the wings as cooling/ condensers.
Hi Ed . That was very interesting indeed. Unfortunately like many innovative plans like this, many got derailed !!!!!!
Conventional Steam: Use wood or fossil fuels to heat water.
Nuclear Power: Use magic rocks to heat water.
From what little I've read about the Besler, their experiment showed that steam power production dropped as altitude increased due to the effects of colder air on the boiler, condenser, and "fuel".
FWIW: Back in the late 80s or early 90s I saw a presentation by an FAA rep about Aviation. Much of the presentation, what I remember of it anyway, dealt with the classification change to Class A, B, C, etc. Airspace.
One other thing he mentioned {which I unfortunately DID NOT ask about AFTER the presentation} was the concept of steam power for modern General Aviation aircraft.
He mentioned a system using a steam turbine and operating at several hundred PSI, or maybe even over 1,000 PSI. The system would use a VERY SMALL boiler -- possibly around the _size_ of a disposable propane cylinder -- to make boiler failure not totally catastrophic.
Whether this was all just _conjecture_ or had actually been researched to some extent I do not know.
You know it's a good channel when it references other channels you watched.
Or am I stuck in a TH-cam algorithm loop ?
Excellent video. The name Doble is pronounced 'doughble' and is Cornish in origin, I believe. The cars were fine machines.
The first powered flight (In June 1848, was achieved by inventor John Stringfellow in Chard Somerset, by his unmanned aircraft which was powered by a tiny steam engine. Not many people know that,ma bit like the first World Land Speed Record was made by an electric car.
Full steam ahead! What a marvelous idea, maybe an electric motor power aircraft might be a second wind for a more silent aircraft.
Wow, an actual steam-powered plane. I would have lost the farm on that bet !
Thank You for a interesting video .
This could be the future !!
Very nice biplane could you do a video on it? Thanks Ed 🙏
The aircraft may be called a Besler, I'm calling it a Doble for the purposes of the mechanicals.
Basics of "Doble" as a company, like the Three Stooges, comprising of a rotating cast of brothers, with Abner being the eccentric genius, sadly they were better engineers than businessmen... they developed their models A through K (except I). This is complicated by the models A, B and G being built as "Detroit", and models A through F being cars, with G through K as larger designs. Models C through F were developments upon each other, with the letter generally designating a major alteration in design. The model E was seen as the peak in user-friendliness, fast in starting (minutes from cold to "usable" - enough to move at a dawdle) and on road, it did condense it's water with a 35% loss rate (most other condensing had a rate closer to 50%).
The illusive Model F is also the last E chassis - defined as F due to it's significant differences to the majority of E's.
The Model G and H were used in Buses, so were considerably larger... the Model J was used by Sentinel Waggons of Shrewsbury as a basis for their Columbian Locomotive.
Heard of a Russian pioneer, ~1880, who tried a flight in a craft powered by 2 steam engines, but stalled (?) after liftoff & was crushed betwixt the 2 engines, so close 2 being the 1st 2 fly successfully. Wish i knew more...
I heard of that too. If I am not misremembering, he tried to test his plane jumping off a bridge.
And he used small locomotive engines. Literally a flying train...
@@carloshenriquezimmer7543 Not really a flight then.
Turns out the secret to being the first to powered flight was figuring out that propellers need to be airfoils, and spending a LOT of wind tunnel time figuring out an effective design. The Wright brothers broke that code while everybody else was trying to use paddles.
A more extreme example of this would be one of the proposed Me 264 variants that tried extremely hard to turn the whole plane into a flying boiler... and while the steam plane itself never got built, (I think) the company tasked to build the whole system did finish it.
I gather a problem is the long dwell between adjusting the throttle amd the expected result. Power to wait ratio.
When (or if) you have no oil, these will be common. Like private cars in occupied Europe during WW2 using things like coal gas and steam. Don't do a loop though! Thanks for a very interesting plane and powerplant video.
1890: Frenchman Clément Ader made the first leap and rose 20 cm above the ground using a steam airplane. Check it out it resembled a giant bat !
Too bad that isn't recreated with modern materials and powerplants. His propellers are so inefficient for the rpm and torque put on them and the frame. That thing was weird looking but I see possibilities.
That would be fun.
VERY steampunk airplane, something straight out of a novel! imagine if combustion engines neevr took off and instead steam engines got improved to that point, i can already imagine all sorts of things out of this!
In was thinking the same thing.
Thank you for this look at a unique & interesting piece of aviation history.
If only John Hartford could've flown in one. Gen-u-wine authentic old-fashioned steam powered aereoplane indeed! Thanks Ed.
Now that was a first for me learning about a steam powered airplane thanks Ed what a hoot. 👍
Are there advances in Steam boilers and condensers allowing a remake of Besler steamer airplane engine?
External Combustion Engines, Steam machines and the heavier as a brick Stirling, could work on everything that burns.
With AvGas about to be banned in places as California-A, always expensive and hard to find in many countries, Aircraft Steam machines are not that krazee now.
What happened to the German research on Aircraft Steam Turbines?
This sounds as a perfect companion to the Nuclear Reactor tested inside a B-36.

There was also a military project in the 1950/60ies on steam powered helicopters. A single seater named "Dragon Fly" and a double seater named "Atlas" were built und tested. The last presentation of them was at the Farnborough Air Show in 1998.
But these helicopters had a very special steam generator, which uses 95% hydrogenperoxide and a silver catalyst and a very light weight engine. Today the use of such high percentage hydrogen peroxide is forbidden, because it could become very dangerous.
Such steam generators were also used to operate rocket belts and jet packs.
A silent surveillance aircraft for limited areas would be a powerful asset in many conflict scenarios.
The first aircraft to successfully take off and fly under steam power was Hiram Maxim's test bed vehicle in about 1884. As it was never actually intended to fly, just test the concept, it had no control surfaces. So, it was not counted as a controlled filght
The quietness of the plane makes it seem worthwhile to develop.
Electric planes are very quiet, probably quieter than the Besler could ever be.
There was a song titled “Steam Powered Aeroplane” by John Hartford back in the ‘70s
You could spin an absolutely ludicrously big propeller with one of those. In fact, you could probably spin the whole aircraft like it's nothing, lol. I don't know if I like the idea of a fire being on the plane at all times, specifically, an exposed flame.
When I was a kid in the 1950, the Bessler was never mentioned the idea of a steam-plane seemingly dying with Hiram Maxim's failed attempt supposedly over-shadowed by the Wright Brothers and their internal-comustion engine. The history books really need to be re-written!
I’m just amazed that this was the 1930s and not the 1910s or earlier.
I worked with Bessler's grand daughter about 15 years ago. She told some cool stories about him. Her parents have some of his drawings of engines and stuff.
I have interviewed as many people as I can find because I plan on writing a book on him. Can you send me contact information for the grandaughter? I was told that the daughter was only interested in horses and did not save any of Besler's steam stuff. Tom Kimmel
@@tomkimmel8726 I will see what I can do and pass on the info to her.
The comment about the horses made me LOL because she is (was?) a barrel racer and a horsey person 100%! I got the feeling that she did not realize the impact her grand father made on the world we live in. I might be wrong about that, but that's the feeling I got at the time.
There is a steam engine at the Wichita Ks AIR MUSEUM too.
My goodness. Ed, will you ever run out of rabbits to pull out of your hat? Just a perfect little episode.
Steam engine for aviation 🤔. I've heard of a worst idea
how about a plane with an atomic reactor! What could possibly go wrong? Thanks for another excellent video.
That was also a steam engine.
'Steam Bird' by Hilbert Schenck (1988) describes the 'possibility' of an atom reactor driven giant airplane...
nuclear aircraft propulsion was seriously proposed and partially developed.
en.wikipedia.org/wiki/Aircraft_Nuclear_Propulsion
@@awatt Nope. The way they'd have used reactors to power aircraft had nothing to do with water.
@@immikeurnot
How then?
I can wait.
Now I am sorry I got rid of the superheated steam tables book I had when in undergraduate engineering school.
I wonder how good a modern version could be with water recovery and the latest materials science and super-efficient radiators
I just love people who have to try 😅 even if it will never be, you learn from it. Fx) You do not have to cranke the engine, it starts when the steam is on. ) You can reverse the engine, stopping fast. ) You can speake to the person beside you. ) Sems you could speak (loud) to people on the ground.
And ofcorse today we are getting moore and moore
experiment with electric
propulsion, who have some similarity with steam dito.
Slight problem, the aircraft would have to carry water as wall as fuel.
That adds extra weight and reduced weight is paramount on an aircraft
I knew about the Besler streamliner train, but I didn't know they built an airplane, too.
It is said that 747s had steam assisted take-offs. They had to pump cooling water into the engine - obviously this turned into superheated steam, producing increased thrust.
I never heard of any 747 with water-injection. The early models of B-52 and KC-135 used water injection at takeoff to support getting a greater payload into the air. The water tanks would be close to empty by the time they reached a good altitude.
@@kirkmooneyham water injection was proposed, tested, and even used commercially in lots of airliners, decades ago.
@kirkmooneyham As I said, it wasn't intentional water injection - the extra thrust was a by-product of the engine cooling effects.
@@stoobydootoo4098
I believe with water injection (and the related methmix) the additional thrust comes from an increase in the engine’s mass flow rate due to the enthalpy change of liquid water to steam. So you’re right that the water acts as a coolant, but its purpose was to cool the air (not to benefit or cool the engine itself), and by doing so it increase the density (mass) of the working fluid. Change in working fluid momentum = mass x velocity change = thrust.
Interesting. I knew of this aircraft, but not that it used Doble's technology.
Perhaps the condenser was a WIP, as it makes no sense to add one if you’re not reusing the water. Certainly not in a plane, where pounds count, not to mention drag.
I may be mistaken but I think there is a steam airplane at the Air Force Museum at Warner Robins.
The Bessler Brothers actually made steam powered refrigeration equipment…
The Jacuzzi aircraft would be another example for consideration…
You should add John Hartford’s great song, Steam Powered Areoplane.
What a deal....Thanks Ed Nash.....
Shoe🇺🇸
Uears ago I spoke with a 2nd seater of that plane
He stated the plane had no theoretical ceiling
I'm fairly certain that Henry Maxim, who went on to invent the machine gun, built and flew for a very short distance a steam-powered airplane which he flew in a London park. I can't swear to the date but records definitely exist including a plan of his engine.
The boiling point of water drops with increasing altitude.
So a plug in (the kettle element) hybrid steam plane should be able to take of and climb with (close to) zero heating.
Once up to cruise altitude, very little extra energy (in the form of a std fuel) required to keep it cruising...
How does one keep stoking a fire on a steam aircraft? Plus coal or oil and water . Boilers would had added too much weight
You immediately mad me think of the nuclear powered Tu-95 and B-36, but neither used steam to fly.
are you sure about that? how does a nuclear reactor generate electricity?
@@SoloRenegade The Tu-95 only carried a reactor aloft to see if it could be operated inflight, the B-36 was testing two different air cycle propulsion systems.
@@luvr381 I say again, "how does a nuclear reactor produce electricity?"
How does a nuclear reactor power an airplane?
stop avoiding the question and just answer it.
@@SoloRenegade Neither of those engines used electricity to propel themselves.
The two broad types of nuclear aircraft propulsion are Direct Air Cycle, where air is ingested into a jet's compressor, then funnelled into the reactor where it is superheated (and the reactor is cooled) and then funnelled back into the engine, into the turbine section and then out the back. This is a turbine engine where the combustion chamber is replaced with a nuclear reactor.
The other type is called Indirect Air Cycle, and has a working medium (steam or molten salt) passed through the nuclear reactor then into a heat exchanger inside of the engine. This heat exchanger replaces the combustion chamber in a conventional turbine engine.
These approaches work for turboprops and jet aircraft.
The B-36 was a piston powered aircraft (primarily), but the experiments in which nuclear reactors were carried by B-36s were only to determine whether the shielding to protect crew and equipment could be carried in an aircraft without compromising safety or payload.
There's no need to be so demanding of @luvr381, they'd replied to you once (when I was writing this comment, at least), and all of this information is available online.
@@SoloRenegade likely by doing the same as nuclear power plants do, use nuclear to produce steam and convert the pressure of the steam into electricity.
though not much is known of how these test beds worked.
Steam everything - NOW. What's the hold-up?
I have a book which claims a German company, near the end of WW2, was working on a 6,000hp steam turbine aero engine.
Gyro Gearloose once invented a steam powered piloted rocket 🚀 but it emitted so much smoke that he couldn’t see if he ‘d got airborne or not.
& when he did, he lost power so quickly that his craft crashed into City Hall.
The Stanley brothers had their own steam aircraft as well.
