How that tiny engine made that metal rod glow and bend is insane. Imagine this little engine being 100x the size.

Maybe you need to add an aerospike so the detonation has something to spin around. The Miles-Bach-Michalski engine has a central spike though it was truncated. Another thought is to move the primer to the back of the device instead of the exit port and angle it to induce rotation. The MBM engine had their starter in that position. Also being in the Northern hemisphere you will want to spin anti-clockwise so you aren't fighting the Coriolis Effect.

The gunpowder in the shotgun shell won't explode until its confined. Pistol powders burn faster than shotgun powders. The explosive in a modern primer is usually a combination of things based around Lead styphnate. As alternative sources for detonation; You might be able to use something like Armstrong's mixture (usually available premade in pull string fireworks, kids capgun toys, either the red paper strips or the little red plastic 'loads'). Or, the mercury fulminate from party poppers, snap pops, adult crackers, ie the fireworks you throw against the ground.

But rocket engines don't have that, so simply replacing props with rocket engines will result in a hover-only drone. Instead it would be best to do it the way NASA did with their Project Morpheus; a single rocket engine to provide hover thrust and smaller engines to stabilize it and provide side thrust. Which brings up the point that NASA's already doing that. Also, don't beg for likes.

Plus, geometrical bump from the initiator might disturb the shockwave. You don't want to have shockwave echoing around especially because it doesn't have guiding inner cylinder in this case.

Hey there Mr. Integza!!! I just wanted to say that gun powder does explode. It just needs to be put into a container. When you ignite the powder it quickly turns into gas (keywork: quickly). When the container can no longer hold the pressure of the gas released by the gun powder then the container rips apart allowing the gas to be expelled forcefully in all directions. That's an explosion.

You can make a suitably sensitive primer type powder using Armstrong mixture from matches. The gun powder you used is actually smokeless powder, it’s nitro based and burns slowly at stp but burns much faster under pressure.

This is an old video but it needs to be said that you must be EXTREMELY careful when removing live primers if they sre old or just particularly soft or sensitive they can detonate when you are punching them out and its a good way to lose an eye or really burn or injure your hand or fingers especially when tapping out shotgun primers as the punch acts like a firing pin in a firearm be safe and be careful and mindful when you are removing live and unspent primers

For a second i thought you were going to attach the jet to the RC car...

Primers used to be mercury fulminate, but now they can differ between brands in their composition. The main thing is the powder, it must be compressed very tightly to itself and in a confined chamber to achieve the reaction speed you want just like it is when the shotgun shell is put together. It can also be rather hard to ignite properly which is why the primer is used for repeatability.

If he uses some kind of burst disk to momentarily contain the powder, he might achieve detonation

The "Centerfire ammunition" article on wikipedia goes into detail in the primer chemistry. Short form: mecury is not used anymore, modern compounds are really complex and contain lead, although some "green" ones are starting to get more popular.

Yeah, it's funny how they switched from Murcury Fulmenide when they figured out how bad Mercury was... But what they changed it to was Lead Azide, because they didn't know how bad lead was yet... Now the standard is some kind of weird organic compound I can't remember the name of. Well, unless you got ammo made in the third world, then it probably still uses lead and mercury compounds.

After all these engines, I'd like to see you build a generator! A turbine gen like a jenbacher would be pretty cool.

As improvements to the project Add a bigger tank as used with paintball guns Add additional cylinders and better air injector valves.

this engine is just so cool. from the looks of things, it seems to be very similar in design to an aerospike jet engine, but instead of just having linear air pressure, it spirals it! at least ti'm pretty sure that's what it's doing. from how their design looks, i think they aren't just using high pressured air, i think they're actually spiraling the air around the central cone to create that high speed shock wave needed for detonation to actually be useful. otherwise it would just go straight no matter how powerful the detonation is. basically, i think the thing needed to cause the spiraling effect to occur consistently, would be to angle the extremely high pressured air tubes either clockwise, or counterclockwise around a fixed central cylinder, like an aerospike. that way the high pressured air actually spins the fuel, rather than just pushing it out faster. At times like these, I wish i were better at 3d modeling.

I kind of want to see more from this RDE guy. Super interesting subject and he's very engaging! Also that setup is absolutely rad!

A very neat test! I don't think you got to actually make a rotating PDE - but that is a descent attempt. I would love to see either form of 3D printed PDE actually taking off up in the air. It probably will have to be a theathered flight test... But I am doing more than just asking - community effort, right? - I'm also offering - I am more than willing to machine parts for the project too!

It’s like spinning water to get it to drain faster, you spin the detonation to get more thrust through the same size hole. It’s not that complicated.

You know if you build a simple wire EDM lathe you can make parts with tungsten, and I hear that handles heat pretty well

Tungsten is about $100-$350 per kilo on average. And tungsten is *heavy.* A 4 inch cube of the stuff weighs 41lbs. (18.597kg)

tungsten is extremely expensive, heavy and hard to machine, and EDM lathes aren't exactly mainstream equipment. even just upgrading to aluminium and brass would allow him to do so much more, and if he gets the equipment to use aluminium and brass he could also use some steel. let's not skip half the ladder and go straight from 3D printing to actual rocket science, that would be a bit silly.

Unfortunately, tungsten is also very brittle. Tends to crack and handle pressure and vibration not very well. Even so, an alloy containing tungsten maintains many of its thermal properties without inheriting brittleness.

You’re a massive inspiration. You make high level research accessible and understandable. Part of me wishes I was still in physics.

Thank you for your time and effort in this.

This is something straight out of science fiction, like some alien spaceship thruster

I believe if you add a little bit of restriction to the nozzle of the engine, like the metal one in the lab, it will allow for a little bit of pressure to build on the inside which might help promote better detonation. It seemed that you had an original detonation followed by deflegration

I don't think you need restrictions on RDE. Whole point of RDE is that the exhaust is already supersonic without use of nozzle.

@@3ch0_17 I guess that would make a pressurized fuel mixture judging by the flowrate they use. Which would help greatly if your goal is to make a lot of thrust. But would the 3d printed part of integza withstand that kind of pressurized explosion...?

I like how much he never lets anything get him down, he keeps saying n trying.. it’s great!

The lab engine used a metal cap over the tube which forced the engine to decide it's rotation. With your engine you might get some rotation but you can't see it since the exit is a hole. you probably should try to restrict the exit point but then get ready to run. It will be like a bomb for real if you make the opening too small. I suggest trying to use the worse quality air for combustion so that it might have less force but you can abuse the cylinder more.

I like your way to explain every thing

I love watching the evolution of your content from your first engine tests, keep it up and the quality keeps getting better!
