In this series, we'll be taking a deep dive into the development cycle of the DB 600 series of engines. An evolution fraught with issues directly related to decisions made by the German government - from metal scarcity to inferior fuels- we examine how German engineering overcame these limits in innovative ways.

FYI, was Otto LUTZ, who actually did the initial chemistry research on Nitrous. Otto Cuno did a lot of the subsquent research into putting it to use in actual aircraft. :)
LUTZ as in current clutches?
Thanks Calum! I think I must have misinterpreted that bit. It goes without saying that I love your book. Let me know if you’d ever be interested in giving one of your expert presentations on the channel!
@@flightdojo - Its an extremely dense book, thematically and technologically - so tiny slips like that are inevitable. Yes of course we can do a presentation. You can contact me via the contact form on my website, or track me down on Twitter.
@@CalumDouglas ACTUALLY…it was sir Fredrick Nitrous in the 15th century who invented it, to speed up his horses with the push of a button to evade law enforcement. When breathed in, it was said to add 1 horsepower, since it made his horse twice as fast as other horses. FYI
@@nicholassilvestri1804 I'm guessing it used farts for propulsion
By the way, the fuel injection system developed by Bosch for the DB 601 series engines was dusted off after the war and after miniaturization, implemented it on the inline six engine on the Mercedes-Benz 300 SL.
That I didn´t know!!!//Lars
Not true. It was direct injection on the DB601 onwards, the 300SL used a fairly normal mechanical injection into the inlet manifold. The 300SLR (not the same car although similar looking) did use direct mechanical injection from the W196 GP cars
@@zaphodbeeblebrox5973 Oops! Typo error there, it was supposed to be the DB 601 instead of the DB 600, silly me... correcting it now.
@@zaphodbeeblebrox5973 The street 300 SL Gullwing engines used direct fuel injection, not port injection. It is one of the iconic technical advances of that car that established it's place in automotive history.
It's funny that the best part of a century after aircraft first had fuel injection, actually more than a century for a small number of engines, but let's just assume this is an early mass market fuel injected engine. Anyway, here we are best part of a century on from warplane worthy fuel injection and yet if you buy a brand new $100,000 aircraft engine it will default to having a carburetor and magneto ignition. Like a model T Ford or a pre war Vincent motorcycle.
I have worked on German designed engines and transmission systems most of my fifty-five year working life. One thing that cannot be denied is that they really do design their products well. I have compared a lot of different products with similar products from other countries and they don't compare to the German designed product. Yes, I may be a female marine engineer but I was trained in Germany. Thanks, Laurajane from New Zealand 🇳🇿
what do you don't like about the french naval diesel that are built like a giant car engine?
Sarcasm
@@anuvisraa5786 For a start, I have a masters degree in marine engineering,secondly I am a female, third I was a chief engineer for over twenty years. I have been involved with a lot of machinery built in a number of countries. I can honestly say that the French have a penchant of doing things their way. Perhaps that is why they are somewhat unheard of!.
Engineered like no other.
@@johna.s.3847 Well at least there is a like.
My dad worked at the same facility Von Braun and he admitted he got his ideas from others. Go Cubs.
German engineers sure were not afraid to experiment and try different things good examples are the 90 degree infinitely variable superchargers on their v12s and the fw190 A series having a full mechanical computer to automate all engine controls so a pilot only needed to adjust throttle position.
@@belliduradespicio8009 Take a look at the TH-cam channel "Greg's Airplanes and Automobiles". He has a video looking at the details of the engine control system for the BMW 801 in the FW190.
Germany had engineers, but America had hot-rodders and gearheads.
@@oldchap1228 nearly perfect ;-) Kommandogerät (commanding device)
The first application of an engine management system, years before Volvo, Renault, fitted such systems to their cars and lorries.
@@oldchap1228 yep, you butchered it: Kommando Gerät.
Wolfram Eisenlohr said years later about the RLM specifications for inverted engines that the main reasons were that the lower exhausts would not blind the pilot during night operations, the inverted installation was more compact, and the pilot would have better visibility.
A little known advantage of the inverted V engine was the ease of access by the ground crew. A High percentage of maintanance could be done from the ground.
@@petersattler3454
that's why they were called 'ground crew' instead of 'aircrew' lol jus kidding
Also, in the developing dive bomber blitzkrieg concept, an inverted vee engine was determined to aid accuracy (longer visual time on target). As Germany had, from a production resources standpoint, to standardize on the minimum necessary engine designs, this became one more important factor arguing for inverted inline a/c engines.
Another advantage of inverted DB engine notice by pilots who flew both the Merlin Bouchon and DB engined 109s was the lower exhaust noise in the cockpit.
It also allowed a lower center of gravity for the engine while allowing a cannon to fire through the prop. I believe it also improved aerodynamics by reducing frontal area and the pilot has greater visibility over the narrower engine profile.
I thankfully worked for Bosch for 42 years rebuilding gasoline and diesel injection pumps for Mercedes Benz, Porsche and assisting engineers developing diesel injection pumps, rails and injector systems for Cummins, Navistar, Onan, GM, Ford, John Deere and Chrysler. I did see an example of the stunningly impressive, purely mechanical 12 cylinder inline direct- injection gasoline pump used on the DB600 Series engines in the office of a WW2 Engineer Hermann...(can't remember his last name) damn it.
I cannot imagine a better job then doing that all day long I have a smile on my face every single day.
Onan wiki
Boring, his name was Hermann Boring
Goring
My fuel injected M100 with its mechanical fuel injection and inbuilt altimeter really sounded like a bomber taking off. The nose of the 6.3 would lift as the massive torque hurled the car forward. That fuel injection system was based on WW2 aircraft!. Well made and very durable.
Keep at it with this engine series. It's fascinating
Liked and Subscribed. I appreciate the historical perspective from the context of engine development. I find it fascinating as a person who loves anything with pistons, valves, wheels or wings. WWII Warbirds are amazing feats of engineering. Thank you for making this content and sharing it with us.
I am reading that book right now. A lot to digest. Amazing what design problems a nickel shortage can cause.
And to think the Ukraine incident is causing the nickel price to be incredibly expensive
Finally a video about 600-series!!! Awesome, thanks
Man putting out these videos so fast and so komplex thank you really good work.💪
My grandpa, several years after ww2, stationed outside Berlin during the cold War, got to acompany a base call as their truck driver to a rediscovered concrete storage facility. It was albeit small, but it houses barrel after barrel of aviation and diesel fuel, as well as cotton packed crates of unused and still mint condition stg rifles.. he still has one of the bullets that was in a storage crate in his memories trunk
Many veterans, old and young alike that grew under Hitler would hide or not report guns for when "the reich would come again", even after defeat. Could be one of those types of situations.
Your gramps didn't get one of those Stg 44s?
@@kristoffermangila sadly not. He couldn't quite recall the situation on who technically owned the objects inside after opening. He snuck the bullet out as a keepsake though
@@trevortammen2341 oh well, at least there's the bullet...
I almost forgot how excellently your videos are made. Hats off to you! Happy 4th of July everyone!
Very well researched content (I’m sure from the attributed book at the outset) that finally explained many things I had been wondering about for a while. Great info.
Great stuff, looking forward to more. Thanks 🙂
Wow! This is AWESOME! I got to your end screen, and just went "NO!!! I want more!!!!"
Give me more!
This is an AMAZING engine! WOW!
Man those old aircraft engines were just bad ass looking,they were imposing, like a huge can of wupp ass and some looked really complicated, excellent video,love youtube.
With a name like Flight Dojo, I expected a sensationalist Cobra Kai of airplane You Tubers but I decided I wanted to give it a shot anyway. I got a very pleasant surprise. As soon as I realized how you were going to cover this topic, I was interested. When you plugged Calum's book (which I have read, and it is excellent), it was very obvious that you were the sort of person who does their homework. Your delivery is clear, the background music doesn't get in the way or grate on my nerves, and your choice of visuals is nicely done.
In short, subbed.
Thank you for the added pictures video and sound with your documentary it made it better to watch. Good sound
Very interesting. Thanks for making this.
This video was 🔥 ! EXCELLENT JOB ! 👌😎👍
I always love finding these channels that make history sound as cool as it is. History is FUN AGAIN!!!
Thankyou!! I was hoping you would cover the db series 🤟
What a great program! It is excellently presented and great knowledge etc!
Excellent with loads of information. Thanks a lot.
great video. can't wait for part 2
Superb info, thanks for making this available to the fans of the ME 109 wich is a technological beauty.
Cheers from Costa Rica, C.A.
Great Video, THX F.D. 👊 😎
Great work, many thanks
Thank you for this informative video. Learned a lot.
Wonderful information and shots. Also love the wonderful comments below from engine efficionados.
Fantastic! Thanks for the time and reaserch that has gone into this. I loved the making the Marlin engine and the lengths and depths they went too {Ford V8 is another} but there is nothing similar for the Germans. This is the next best thing.
Love your channel! Would love to see a vid about how DB squeezed a cannon barrel in the “V” of the engine. Can you imagine the complexity of design and the maintenance nightmare that would entail!
Keep up the great work!
+ Turbobus The cannon is sitting between the feet of the pilot, and the blast tube passes through the engine VEE and a hollow propeller shaft. So not necessarily complex, just hard to reach.
it was actually very simple German aircraft were very simple though they did have the worst motor cannon Russians did it far better without much fail their guns were just a whole lot more powerful it actually broke the plane
Much less complicated than a double row radial or a Napier Sabre.
The massive 30mm cannon mounted inline was a major advantage.
Not really. It is an empty space. No harder that accessing a lot of guns. The main difficulty is making sure the vibrations dont screw with the engine.
what amazing detail. thanks for all the effort you put into these videos. they really are a new high standard of WW2 engine information.
They are a beautiful work of art! Amazing looking engine!
Please do a long form series on the old stuff like this. I'd eat that shit up! Awesome work
Great channel! Great work! 👍
Loved the video .I really enjoyed it
This video is so good.

Superb video!
Nice and informative!
I recommend reading Antony Sutton’s books-
Some of what he revealed was the fact that Standard Oil shipped tons of Tetraethyl to Germany, and the technological exchange(later covered up) for the German Synthetic rubber.
Lots of facts were hidden post war-
Between the wars restrictions had Junkers build planes in the USSR, and they made the first all metal plane.
In the post WWII period, the Soviets acquired BMW and Junkers jet engines, thousands of engineers and scientists and complete Heinkel factories. Siegfried Gunther in fact was the designer of the Mig-15, with Rolls Royce Nene engines the Soviets obtained with “irresistible pressure” and then improved upon.
The same small group of Wall Street Bankers who financed the invasion of Russia to create the Soviet ”Union” to exploit natural resources, implement US Corporations, technical assistance(at extreme profits)also re-industrialized and invested in post 1923 Germany. Sutton’s books are a fantastic source of info(especially from hidden State Department Decimal Files)
Carrol Quigley’s “The Anglo-American Establishment also shows what the English were doing in the post Versailles period, doing a “controlled buildup” and financing of Germany.
The 1935 Naval Agreement where England allowed Germany to build up to 1/3 of the amount of British superiority.
Also of interest was Ferdinand Porsche’s contribution to aviation engines, hemispherical combustion chamber heads, etc.
ITT owned 19% of Foke-Wulf if I recall correctly. Opel was GM owned from 1931-2017, and Ford Factories continued building through and sfter the war in Germany, England, France and as the Gaz in the Ussr-
To say that “things got out of hand” and history is a coverup is a pretty accurate statement-
Economic ties with hostile regimes probably happen all the time. Wallstreet and the Communist Party of China are also closely tied together.
Well now I know.
There is much work being done to uncover the facts. It would be beneficial to back up claims with sources to preclude muddying the waters.
The fact of the matter is, when you open an automobile factory in Germany in the 1930s it happens to be predominantly Germans who you employ. If a percentage of them join the Nazi movement and takeover the country (by democratic vote I might add) then the National-Socialists socialize your factory. It was not Ford the man, nor the company, who operated a Ford plant throughout the war. It was Nazi Germany who operated it for their own benefit after confiscating the means of production in the manner of ALL true socialist nations.
Ill Add, Standard Oil literally produced the very first 100 Octane fuel ever, and they delivered a shipment to the UK at the onset of the Battle of Britain. Without that one ship full of aviation fuel, there is a pretty good chance the Battle of Britain would have ended a complete and total loss in the air for the Brits, and the worst hand to hand fighting of the war would not have been on the beaches of France.
You want some more well known facts? After WWII the British Labour Party (Socialists) SOLD the greatest military secret they had, the Meteors upgraded Turbojet engine to the USSR because they were Commie sympathizers. That EXACT engine which pushed the Meteor to 606mph, ended up COPIED by a gross violation of intellectual property rights, and ended up in the skies over Korea in the Mig-15. The Mig-15 also utilized the exact same NACA reports on flow through aerodynamic bodies, nose inlet imbedded jet engines etc. They ended up with an F-86 Saber copy without ever seeing one because of the NACA papers which were funded by US taxpayers.
Then the US hem-haws around while they KNOW Russian relations have soured in the Late-40s into the early 1950's they stand by and ALLOW the USSR to develop their own nuclear weapons via world class espionage, theft, and once again carbon copying what the West had already done a decade before. If they had been stopped before 1951-52, there would have been no cold war, no Korean war, no rise of Red china, no Taiwan dispute. And and there would have been an end to Stalin. And they would have killed millions by dropping a bomb on moscow, but it would pale in comparison to the 20-80 million people who died in Russia and China in the 50s-70's to starvation, lack of food, water, and of medical treatments.
But all those American and British idiots are dead, and now their children run this country and the rest of the world. To scared to call out Putin as Evil. To scared to rattle Fat Kims ego, wont even drop pamphlets to N.Korea to show them reality. To scared to call out the Communist leaders in china. They stand by while the Chinese hack and obtain every secret we ever had and begin flying around in 5th gen stealth fighters and nuclear submarines, when they lack any and all means to develop those themselves.
And So it will only get worse.

Aside from Antony Sutton’s books(start with his first Trilogy, “Western Technology and Soviet Economic Development”) then “Wall Street and the Bolshevik Revolution”, “Wall Street And The Rise Of Hitler”, and “Wall Street And FDR”.
Mr. Sutton was a professor at Stanford and had access to the Hoover Library-he snooped where no one ever thought that so many decades later someone would go looking for State Department Decimal Files for evidence. Things that are hidden not only from the public but to most other elected officials.
Further enlightenment comes from reading Douglas Reed’s 1956 book(only published in 1978)and Carroll Quigley’s “The Anglo-American Establishment. From the days of Cecil Rhodes and Alfred Milner, who really ran that Empire, through the secret Milner Group, Inner Circle, Round Table and Kindergarten.
And where do you think the Germans got funding post WWI/Versailles? Especially after 1923?
The Masters of Deception have done a great job at hiding things, coating history with a daily layer of lies to keep it that way. MacArthur discovered the truth about the Korean War, and he got immediate retirement and a parade. Patton got run over by a truck before him. People still don’t know what the Vietnam scam was after all these years. Some American pilots that flew far north were confused to see Ford trucks, which were in fact soviet Fords-
So interesting. Great detail and presentation style. Subbed here!
A real masterpiece of aero engines !
I have always loved/been a big fan of the DB!!! Everything about it 👍
still looking forward to another episode in this series :)
The fuel injection used on the DB engines was not electronically controlled. It used a mechanical design incorporating what was known as a 'flapper box' (by the sound it made), which metered the fuel based on several mechanical inputs.
Amazingly done video, as always! But imo the darkest of the darkest on the dark side imo is the Jumo 213 ⚫️! Truly an engine of the darkside!
I own a small part of one of these engines that was recovered from the wreck of a crashed Heinkel He 111. The really amazing thing about it is that stamped into the metal are 3 words......'Made in England'. Didn't find that until I'd cleaned it up. (I obtained the part totally legally from a museum that was getting rid of some bits that they didn't want).
Pre- war no doubt.
@@michaelbooher339 That's the only explanation I could think of, unless the museum just got the part mixed up and it wasn't from the aircraft they said it was from.
@@24934637 England was not very careful / smart with there technology in the 20’s - 30’s. AKA the Whittle engine.
@@michaelbooher339 That's very true. I'm sure that there was something that was sold to the Russians in the 1950s that in retrospect was a massive mistake, but I can't remember what it was.
@@24934637 The Whittle jet engine technology was lost to the Russians in a pool game.
The DB 604 X-24 was an engine with an X shaped configuration from the same company. Always loved this engines crazy design.
A lot of great info here but also some major inaccuracies. Love the channel and the engine histories though!
Major innacuracies like what? - Be specific and give time stamps.
There are also videos on TH-cam of the DBs being rebuilt, very nice details on valve train/heads etc
Awesome detail.
Amazing videos !
Most interesting, thank you very much! Subscribed...
Funny that I sat with a Vader shirt in front of my screen hear you talking about the dark side :D
I love this old engines, would love to fly with an old WWII fighter in the future, but I think it will be a dream forever.
Greetz from Germany :)
new sub! Fascinating stuff.
I am so pleased I have discovered this link! Great content, well put together and objectively put! I get a bit tired of the rhetoric exposed by some that everything was about the Spitfire Engine and the Rolls Royce Merlin engine; so much history has been written by the Victors as it has always been throughout history! Once Again Thank You.....Regards From New Zealand
Not only so much history , but so many lies !!!
I LOVE the starting sound, Music of that engine. 😎❤️
Great video.
In regard to Rolls Royce Superchargers, it is interesting to read Sir Stanley Hooker's Book " Not Much of an Engineer" where he talks about his input to improve the design.
One of the best books I've ever read. Written by such a pivotal figure himself, no interpretations. Highly recommend it to anyone interested in aircraft engines, piston or turbine.
@@PMcKay00 if its british im not interested.
@@florencemodina6293 fair point. I mean, what did the British ever do for aero engines?
Have you seen TIK and his channel history has been written by the losses to make the Union against the USSR more palatable
@@gingernutpreacher TIK knows his stuff, he's dedicated his life pretty much towards his craft.
Nice work.
This was bad ass, very interesting
At 01.10 . The pilot is Adolph Galland who ended up in Charge if the Luftwaffe Fighter Command . He started flying ME 109’s in Spain in the mid 1930’s . My dad an RAF Mustang Pilot met him at a reunion he went to & Galland was the Guest Speaker.
+ Beagle76 The wreckage of an original Condor Legion Bf-109 was found in a dump in Spain way back in the 1980s. It has been under rebuild to fly and I think it will be stunning when it is complete not long from now.
Small boo-boo: you mention the development of electronically controlled direct fuel injection @13:00. The direct injection was of course mechanically controlled on the Bosch system, through the Genius Kommandogerat system. Electronics were only developped post WW2 with the invention of the transistor.
Nit picking of course, this remains an excellent video! Thanks for producing it.
Yep. That Bosch system is exactly the same as Bosch produced for the 1969-1973 Porsche 911, and also for race cars like the 917 and the 935.
the nazis were highly developing electronics based on the vacum tube
I always get a kick about the story of German pilots when they would inspect a fighter that had been downed and would say "what the fuck are all these levers for?" ha ha ha ha
@Alfred Wedmore you seem to not understand rotating comutators/slip rings etc and magnetic pick ups,all of which were used pre transistor
@Alfred Wedmore look fuckhead i worked on leyland buses and they used a mchanical commutator for tachometer and speedometer that turned 24 volts dc into a variable frequency 48 volt 3 phase output to ac motors in tacho or speedo,i dont know of any similar system in use today,i am a qualified H/D mechanic with an interest in historical machinery and cars,there were early race V8's which used 8 sets of points to trigger injection systems,you are very ignorant of the past alfred and dont know about what wuld now be considered "dead end" technologys that no longer exist,have you ever seen a buzz box or trembler coil on a vintage car?,didnt think so,STFU
Good stuff 😊
There was an article on this in our Mercedes club of America magazine, The Star. Some thing that always stayed with me was their observation that many of the engineers that were working on this had previously worked on their magnificent silver arrow Grand Prix cars of the 30s.
IIRC Rolls-Royce was considering an inverted design but abandoned it.
I don’t see any semblance of “evil“ in this engine, just magnificent engineering.
Better center of gravity, mechanics didn’t have to climb up on a ladder to do most of their work and stoop down, not to mention the innovative Bosch fuel injection system which continued as a basic design into Mercedes Benz gas cars through the 1960s.
The pinnacle of which was the fuel injection system used on the Mercedes-Benz 300 SL.
@@kristoffermangila IIRC the 300SL (for the civilians; the earlier race version was carbureted), had direct injection; subsequent Mercedes did not - but they all used that magnificent mechanical fuel injection pump from the DB600 - which resembled a miniature engine.
That's subscription from me. Love the bad guys 🏴☠️
Alright you have my attention. Subscribed.
An important omission in reporting the downside of straight vanes in the RR turbo was that flat, straight vanes created a definite pulse in the boosted air supply, making smooth fuel/air mix more difficult even with injection. Curved vanes delivered a more constant smooth supply of the concentrated air with even larger turbos being much more efficient than the straight vaned variety.
"The Secret Horsepower Race" is a MUST HAVE book.
Fascinating stuff.
You had me with your Star Wars references. :)
My BMW car is also awesome and so is my Mercedes car, reliable well-made and run forever
Excellent!
Good information please do more on other engines!
great vid
keep it up!
I have a German Ferryman V twin R30 diesel in my good ol' sailboat. Reminds me of a section out of a FW 190 radial.
Perciate it . Good vid kid.
I know nothing of engines and nothing of aircraft but really enjoyed the video.
most entertaining thx :)
My good lady wife got me that book for Christmas as you say it's a very worth while book to have. Also many thanks for this video.
Great presentation! Callum's book is amazing. There is sadly no book dedicated to the DB engines. Neither for the Maybach tank engines. There is a good BMW and another Junker book, the second one, even if very technical does not go deep in the development history or political background...and also both are in German.
It's kinda sad because if engines deserves a book, it's surely those. Well made and high technology.
Interesting. Is part two available?
605 had several problems with mainbearings and lubrication and oil foam when installed in BF109´s because Willy M. refused to enlarge (another bulge in the 109 cowling!) its oil tank which was clearly undersized from that what Merc was recommending ! In 110´s the 605 did last longer (more room for bigger oiltank and for defoaming device "Ölschleuder") but they were´nt flown such hard as a single fighterplane too.
Can’t tell a German he’s wrong….

Marvelous engineering skills
Great video! There was an inverted version of the American Liberty 12 engine coded the V-1650, but not to be confused with the Packard version of the RR Merlin. Not sure what year that was but I think it was before the DB600 series.
Chrysler developed an inverted V12 very powerful one toward the end of the war with No market for any more prop engines as they were going into the jet age. So it was already yesterday's news by the time it past the development stage.
Most likely a 1650-9 a merlin 101
@@tomstulc9143 most likely a copy of a merlin 101
The inverted Liberty was actually around 1100 or 1200 cubic inches. Built by Allison it was also air cooled.
Great program! Can I ask what the music was?
You should look into the Crystler IV 2200 prototype aircraft engine that was suppose to go into the P-47
Thanx for the excellent video, much needed to put some facts in order.
My read of this history is that Germany, especially in the wake of rearmament, made up for lost time, but quickly was brought to the reality that, due to the lack of sufficient quantities of strategic materials, it could not compete in exactly the same ways as the future Allies. So, as higher performance requirements brought higher engine stresses, the Germans couldn't access the necessary & sometimes exotic materials to resolve this, e.g. bearings. Therefore, maintaining roller bearings, and lower boost pressures were required. Yet remaining competitive--indeed, winning--was required, so other methods (larger displacements, GM1, MW50) were employed. I believe Germany was 1st to figure out the knock rating problems, and had more than adequate octanes, but didn't have adequate production capacities. At midwar & immediate postwar, Allies were "scratching their heads" that Germany was manufacturing avgas with octane ratings superfluous to the needs of their operational aircraft.
There's much more to be said regarding the competitive disadvantages with which the Nazis had to contend. Leaving the turbojet story aside, suffice it to say that by VE day, the production war was lost, but German aviation motor technology was evenly competitive with the Allies ( although this would have also have come to a screaming halt as, according to Speer, by May '45, Germany's total supplies of strategic materials would only fill a broom closet.).
Germany recognized before the war that larger displacement engines would be needed to operate at the Maximum potential of aerodynamic technology...
The Rolls-Royce Merlin was clearly too small to meet power demands of modern fighter designs like the Tempest.
Germany clearly had a major technology advantage with the widespread use of Gasoline Direct Injection and variable speed superchargers... this was vastly superior to carburators and fixed speed blowers in every way.
GDI allows lower octane fuels to be used without the risk of damage from "Knock"
*MW50* had another important advantage.. its extended the amount of *TIME* that WEP or emergency combat power (P-MAX) could be used... some Luftwaffe aircraft carried enough MW50 to extend WEP up to 20 minutes per flight, 400% more than a typical Allied aircraft (5 minutes max.)
It was the slotted exhaust ports down low instead of up high on the 109 that 1st fish hooked you. And then you realized it had no oil pan with its dry sump oiling system. And it would fly just fine inverted instead of konking out in a simple -G pushover like a Merlin. And the 20mil "Motorcanone" that fired between its cylinder banks and recoiled into the cockpit. And the ground crews cranking them over like lawnmowers. And the fires they built under them on the Eastern front so they would start. And the...
Fuel injected, inverted. 30mm cannon firing through it. This generation of DBs changed everything .
it´s fascinating in the time context..for some reason it´s more fascinating what they achieved back then considering the technology they had.... for some reason it seems easiert to me to build a stealth fighter with today´s technology than a lasting, powerfull piston engine back then.. .many things back then were designed by try and error
That would be because you have never built a stealth fighter and have no concept of what it takes to design, engineer and build one.
12:53 Small but important point: the fuel injection systems used in these planes were mechanical, not electronic. IINM the first electronic fuel injection system used in a production vehicle, was a Bendix system in the 1950s. It used thermionic valves, and wasn't successful.
Cool!
I had been under the impression that normally-aspirated engines benefitted from valve overlap, but supercharged engines risked pushing some of the air-fuel mixture out the exhaust before it could be burned, damaging range.
Yes thats why you can only do it if you have direct injection.
I have a war run engine at home and its pristine
