Tesla Pulsejet Engine [3D Printed]

Yeah my jamjar jet exploded as a kid too... don't tell mum. XD

"I didn't learn the first time" As a man who has already lost an eye in a work accident, I feel the need to point this out. SAFETY GLASSES. I learnt the first time.

Great work on this video! I think you had a chance of success with the Tesla valve intake, but it was way too small for a chamber that size. Would have needed 5-6 of them at least to feed air fast enough.

"I'm Portuguese, and he is a fake russian" Shots fired!

First time seeing this fella's vids. They're Pretty good. He's like a PG ColinFurze.

This is a special kind of humor, scientific fun and morbid danger; my kind of stuff!

My English is also bad - this is why I understand you so good

First time watching you. You’re like a funnier lower budget Bill Nye the Science Guy.

The "JarJet" needs a larger hole. On the extreme end, a completely open jar will burn continuously, but the flame will "flutter" as the air is (partially) evacuated by the flame and then rushes back in to fill the created vacuum. Burning a candle in a short but narrow tube can create the same flutter effect. As the open end of the jar decreases in size, the gas-air mixture is evacuated more energetically. The "flutter" will increase in frequency and become louder. At some point, as the hole size is decreased and depending on the volume of the gas mixture in the jar, the explosive ignition ejects ALL the air and gas inside, including the heat (flame) necessary to keep the process going. The highest fuel to thrust ratio is at that point just before the explosion extinguishes the process. One of the design considerations of a model pulse jet is the length of the exhaust tube. It not only controls the frequency of pulse, it also retains a portion of the flame from the previous pulse that travels back up the tube to the combustion chamber for the next ignition. The best pulse jet is one that pulses at a double harmonic of the tube length. The longer the engine runs, the more the ignition heat is retained and the engine runs more reliably. By it's manufacturing nature, a plastic pulse jet will self-destruct as it stabilizes because the stability of the jet depends on a buildup of heat. P.S. The reed valves in a model pulse jet are to prevent the back flow of air, not so much the fuel. The Tesla fluid valve for the fuel is mostly unnecessary since the fuel is under pressure anyway.

Nicely done and well produced! You mix the science with humor not unlike ElectoBoom. I predict your channel will grow rapidly, best of luck.

If you use the 3D printers to just create a scaffold for a plaster version, or something of similar heat resistance, I think it would work perfectly without being destroyed. Also, you could take calculations on the volume of the ignition area, the time it takes for each unit of that volume to fully ignite, and then program the spark to go off in those intervals, you might be able to optimize the whole setup to ignite the first time every time.

The way he said pulse at 1:11 was so satisfying

"I placed it inside the onion" i giggled a little too hard at that one

I forgot that i even subbed to this channel. But i am not disappointed.

Pulse jet engines only starts running right when in temperatures well beyond the melting point of that plastic, lol!

Gloves when working with "dangerous" Methanol, but no safety glasses when igniting stuff... Respect XD

New name for the resin printer : the resinator

The amount of jokes that can be taken multiple ways is amazing.

I just discovered your channel and I love it ! You make simple experiments just to see by yourself: it's a way of life. I like to beleive that if somebody already managed to do something I can do it too, nothing is impossible !

I respect your skill in animation, crafting and CAD. Really a maker.
