A machine gun is a gun powder engine. The recoil and/or gas from the explosion is used to drive the machine gun. Use blanks to drive a piston hooked to a fly wheel.
In the firework manufacturing industry the best charcoal was always made from willow. A good friend used to have a black powder licence for pyro experimentation and own use, (non commercial). Had some very interesting times making powder, metal salt stars, whistles and bangs. And some great firework parties. Still got all my fingers.😆
Willow makes fast powder. Pine is excellent for sparking and spritzel glitters, alder is excellent for rocket motors. Charcoal's role in black powder is varied when used in pyrotechnics.
Some airplanes had a starter that took shotgun style shells. A shell would be placed in a firing unit and the explosion would turn the engine. When the engine was spinning it would be fed fuel and normal combustion would commence. You can see this with the Fairchild cargo plane in the movie Flight of the Phoenix (1965 version). There are also youtube videos of this type of plane starting. It's pretty cool.
As a youngster (1960s), I would use weed killer and s*^$& spending many an hour in the garden mixing significant quantities of this stuff (stupid) for the production of my homemade cannons! On one occasion I made such an explosion with gravel as shot, that a lot of neighbours came out thinking it was an WW2 UXB gone off! I had also taken-out a section of next-door's fence, made a ground hole of about 5 footballs and made 1 of my ears bleed! Not so happy dad - holding fast the other ear, made me apologies to our neighbour and help repair damage! Only do this stuff with expert supervision, folks, and at 71 I still have an issue with that bloody ear!
As I understand it, the problem with using pure carbon (which is either going to be powdered graphite or some kind of amorphous carbon like lamp black) isn't so much the purity but the porosity and surface area of the powder. This is why charcoal made from wood is the usual source of carbon for gunpowder, because the pyrolysis (aka destructive distillation) process by which charcoal is made decomposes the cellulose and lignin fibres in the wood. These are primarily carbohydrates and polyphenolics, so the decomposition produces a fair amount of water vapour, along with a massive variety of small molecule volatile organic compounds, which also come out as vapours too. All wood produces some creosote, with dark wood producing the most. Light coloured wood tends to produce methanol (hence wood alcohol being an old name for methanol) and pine woods tend to produce turpentine. But most importantly, when all the water and organic compounds have been driven out, you are left with carbon chains with a lot of empty space in between. This is what makes wood charcoal so porous, which allows some of the powdered potassium nitrate and sulfur to be pushed into those pores, which makes the mixture more even and well mixed. The wet mixing and corning process completes this, because the water (or alcohol) partially dissolves some of the potassium nitrate - then when you dry it back out, every particle of carbon and sulfur is effectively coated with a layer of potassium nitrate: Every particle of fuel gets intimately coated with the oxidizing agent, you can't get the mixture any better mixed than that. Which is why gunpowder which has been subjected to wet mixing and then dried out again burns so much faster.
Used to call them polybombs at work. Rubber glove lots of Oxygen a whiff of acetylene then tie the glove up and wait for the unsuspecting victim. We also evolved to a 2" mortar that fired coke cans using a variation of this propellant. Obviously long before the advent of Safety Elves 😂😂
I have worked with highly skilled old timers who very carefully crafted powders specifically for cannons, and not just generically, but based on a whole load of variables. They would mix and press grains of many different sizes, not just for different cannons, but for different applications. Some powders were meant to burn much slower so that they could achieve maximum muzzle velocity for 'ball' rounds [ironically, these 'ball' rounds were what we would call a 'bullet' shape, and were not to be confused with actual 'cannon balls'] in extra long, taper barreled 'rifles' [what would later be known as 'naval guns', due to the USN knowing that precision was not only important to hitting the enemy, but because they were limited in capacity in their magazines, due to not being an immense fortress]. But also, for charges like 'grape shot', they would use much faster burning powders, some times even intentionally choosing short, smooth bore cannons. Grape shot was particularly good against lines of advancing troops, such as the British during the Revolutionary war, but this poor choice of tactics did not end to practically the end of the Civil war. Grape shot merely needs a wooden plug, and it need not be particularly accurate, and even some stacked leather or raw hide could serve, basically as a 'gas wadding' [shotgun users will know what this is], and the large shot was not so much meant to be accurate, as it was to get loaded and shot quickly when the enemy was getting dangerously close to you, because grape shot could never really be fired with any extent of accuracy, although some attempts in paper, wooden and even brass casings were attempted]. Therefore, a simple leather or cotton pouch, with the right amount of shot, could be loaded into the muzzle and shot. Nothing kept this from scattering as it left the barrel. But since it did not seal all that well, but also, could not actually plug the bore, it was actually much more practical, and safe, to use a faster burning, high surface area grain. It turns out that to this day, shotguns tend to employ this, faster burning powder, as much as precision rifles still tend to use slower burning powder. Science being science, very little has been done to change how this works. Probably the greatest advancements were in high purity nitrocellulose and cordite smokeless powders which were installed in measured off lengths [I have lit cordite, it looks like a little waxy stick, and it burns amazingly slow, but extremely clean, when not captured inside of a pressurized chamber. They eventually did make cordite for large naval guns, but as a whole they have gone on to much more advanced propellant grains for large naval guns which can be extremely precise in their metering out for an amazing number of different ballistic applications.
Interesting. Another idea is to use the pressure from the gasses emitted from dry ice and water . If a proper metal container is used to capture the gasses and a regulator added you can probably get a long run time from a motor or anything else that requires spin for generation . The whole assembly would take a-bit of engineering but could be done and I think the results would be very interesting as a source of power . Have not tried it but it is an idea I have had. Thanks for the share. :O)
Considering you wouldn't need to worry about cooling the metal down .....a modern engine block type approach could be used ( - the water jackets ) ! the retraction of the cylinder walls may cause a contact issue with the piston rings do to the extreme cold ( thereby losing compression) but that's probably easily solvable ! My question is , how much pressure is needed to run a motor that is the equivalent of a standard lawnmower ? I've had the same thought and plan to take a five hp motor and tinker with the idea !
Finally somebody did it. I had this idea a while back and even touched on a possible improvement. Instead of relying on the gas pressure of the gunpowder directly you could even go so far as to use flow entrainment to increase the volume of working fluid at the expense of temperature of course. Think steam eductor pumps. That same principle, everything else being exactly as I had described. I'm glad someone else got it to work though. Just shows that it can indeed be done.
Also one other little caveat instead of using granulated powder for firearms use a solid single grain so it's basically a rocket motor used as a gas generator.
@Slowly_Going_Mad rocket powering an expansion engine idea could be extended to liquid fuels.... Either a monopropellant like hydrogen peroxide. Or hydrogen peroxide +a fuel. Or maybe best.... Hydrogen+oxygen. extremely hot steam without faff/mass/inefficiencies of a boiler. Tank pressure would replace boiler feed pump. No need for seperate water to be carried...fuel plus oxidiser makes it as needed.
@@stevecummins324 I see this type of thing as a novelty more or less and having extremely niche practical applications. And it's not a bad idea. To be fair that's how they run the pumps on the main stage of a liquid rocket engine anyway. But to see someone get it to work with a really dirty fuel like BP that's phenomenal.
Mythbusters did a very interesting episode of household things like flour sugar etc that are no combustible but shot through an air cannon and ignited made them very combustable. Theres 1 common ingredient that was so explosive they still refuse to this day to divulge what that ingredient was. My thoughts were if enough air is in, given the right design an engine could be made that could run on almost anything. Like a dry ingredient version of the old diesel engines
Rudolf Diesel used coal dust in some of his early Diesel engines... So did GM, when they were experimenting with alternate fuel passenger car turbines.
Mythbusters MIGHT have actually busted some myths, but they were WRONG in claiming some things myths and some not. Their primary problem, was that they did not use the scientific method very well. They would use the Hillbilly method, and sometimes the Hillbilly method doesn't work, but it is USUALLY exciting. I am sure that that is why they used that method. Keep up the good work.
That car-with-a-cannon made me think of the "Nuclear pulse propulsion" concept for spacecraft - set off small atomic bombs at regular intervals behind the spacecraft! (See "Project Orion"). ps. The sulphur in black powder also reacts with the water produced during combustion to prevent it damping down the reaction, & improves the burn rate.
Can you explain a hydrogen engine? Doesn't the burning of hydrogen and oxygen result in an implosion instead of an explosion? This would cause a vacuum so an engine would work just the opposite of internal combustion engines, so how would it be constructed?
It evolves heat, check out the equation of state, the pressure times the volume is equal to the moles times the gas constant times the temperature. That's the idealised version that ignores the space the molecules take up. But it expands.
@@tonyguy9762I agree combustion products would initially be a at some combination of high temperature and pressure. A condenser after engine might be useful to add a vacuum pull to engine exhaust stroke. *yes the water needs pumped up to at least atmospheric pressure... but it takes less energy *per unit mass( to do such with liquid than it does for gas.
People ask me why I try to get food grade materials - what they don't realize is that the percentage of material that is not being used (90% iso/10% water, for example) has no guarantee of what that 10% water really is or what contaminants might be in it but that food grade has to test out to ppm or ppb of contaminants which means if you get something like neutral spirits (90% ethanol/10% water) at the liquor store that the 10% water is in fact nothing but water. This is why I use 190 proof ethanol (the highest legal to be sold for human consumption here) for cleaning up after I solder instead of isopropyl - iso always leaves contaminants behind that are sometimes difficult to remove but 190 proof ethanol leaves nothing but water, which when it dries leaves nothing visible.
Christopher Huygens looks like Luke! hahahaha! Nice, mate! Don't you agree? Please post a side by side comparison an have him act out a Huygens experiment in costumer! hahaha
Gets me thinking and almost forgot to comment regarding, the bummer in the advancements in the external combustion engines where those engines are the most diverse fuel source capable engines that come to mind. Almost seems like a cartel conspired to prevent the development and advancements in. Big three or other?

Gunpowder is so versatile, you can make it to burn at any speed, there is also medicinal Gunpowder which is brilliant for curing Gastroenteritis but is barely combustible.
All contemporary illustrations of Huygen's engine and Papin's version show the piston at the top driven down by air pressure. The diagram is wrong. I have found no mention of 15g powder charge. Potassium nitrate is not hygroscopic. Some moisture is always present in gunpowder and contributes to the complex chemistry of combustion. The 'watergas reaction' George Cayley's engine (two designs) worked. He recorded performance figures in his notebooks, available in the Farnborough archives. Medhurst's carriage was not propelled by the cannon but by the engine behind it. The engine is shown in the video but without comment. There have been many gunpowder engines, a few successful. Gustav Trouve produced one based on the Bourdon tube that successfully flew a small ornithopter. Graphite coating on gunpowder, and modern nitro powders, is to improve the flow as most are dispensed by volume. It has no effect on moisture absorption and gunpowder is not sensitive to ststic electricity.
Best charcoal is actually been tested as chard toilet paper. I fallow a channel that shoots black powder gun and he has done tons of testing. as a joke he made some from toilet paper and it was the best he had ever made
I like this wierd engines. Thought about the same as in video but it isnt practical at all because it can easily explode on higher loads and works only with black powder (which can be confusing for normal people, which can lead to health hazards). I think there is a use case in making super fast and super powerful engine that is based on air compressor engine + ar15 bolt action, and use pre assambled blanks, then we dont have to worry abut whole fuel exploading, but the device would have to be pretty sturdy not to explode. But for some emmergancy situations it would pork probably. Also i liked Cody's sodium + water jet engine lol.
There's legal precedents... and wonderful explosions when water and wind mills exploded on occasion. I thought it was 5lbs at one time? I guess if I had a mill I would not want it to be totally destroyed by some military demand.
It's lucky we didn't have tinternet when I was young and dumb! "armed" with this info I doubt if I would have made it to 56YO. Thinking back It's a surprise I have!

Daily uploads are key to staying relevant to the TH-cam ranking algorithm. I have trouble creating something new once a week, so... Sometimes it be like that. 🤷♂️
i dont really like mythbusters, i dont think they do it intentionally but its probably rushed to get to production so they have to move on instead of refining the process too far like when they did the hydrogen car and the used distilled water i think instead of making an electrolyte and they wondered why they didnt produce hydrogen and said it failed
You lost me at 'mythbusters'. As far from science as you could get, entertaining, but would not take anything they did as an actual decent investigation into anything.
Why does everyone pursue psychopathy, by negative judgment, instead of mentioning something positive? Does it make you feel smart, or better than those people?
They found a very explosive household ingredients when atomised in an air cannon. Which they still refuse to divulge. Many non combustible things burn when atomised.

like when they did the hydrogen car and the used distilled water i think instead of making an electrolyte and they wondered why they didnt produce hydrogen and said it failed
this is epic
be careful rob

Also please understand that Robert talks about how myth busters went at it the wrong way

Rubbish
They found a very explosive household ingredients when atomised in an air cannon. Which they still refuse to divulge. Many non combustible things burn when atomised.
mythbusters was GARBAGE
