World's Worst Pulse Jet Engine: In Super Slow Motion

Using a high speed camera to study a primitive pulse jet engine to try to figure out its failures. Had the engine cycled longer it would have melted, but would have revealed the physics behind this simple engine. It's still interesting to watch.

Please comment. If you have any idea where I failed in my design, let me know.




This is filmed at 600 frames/second.

Now that's niftier than neat, and neater than nifty....No reason you couldn't make a simple valveless (or valved one using a dynojet haed) out of thick clear plastic tubing of various diameters. Yes it would melt, but I bet it'll run for while before self destruction. It may even use itself for fuel before collapse.

I probably have 4 or 5 design flaws with this setup for it to work correctly. (comb. chamber size, tube diameter, tube length, valve size, no additional fuel feed, etc) If I could get it to run for 2 seconds it would give me 40 seconds of footage- and that was all I was hoping for! I would think the first thing to fail would be the valve, and then it should stop cycling. I think it would be facinating to watch. Thanks for the comment.

My friend who makes valveless pulsejets would get a kick out of this! His YouTube is BeckTechnologies, check his site out, and send this video his way, I'm sure he could not only help you with the design, but may have some questions for you as well regarding the filming, since being able to slow thigns down may help him figure out how his engines are preforming! Cool music too for the vid by the way!

Thanks! I'll have to check that out. All I was hoping for was to get a few power cycles out of this before it melted down or ran out of fuel-

@jtp0321 Explain what a "reteard" is please.

[bored1980]

Interesting, yet boring.

[earsonsounds]

How about a ping pong ball for the valve?

wtf?

This music should only be used for: Warriors riding over rugged mountainside looking smug, a group of astronauts patting each other on the back, or a camera flying over a desert with some tribesmen riding camels.

This is at Least the best use of this type of music i have ever seen...

[janjan7203]

nice!! it could launch a missile and land it on the same spot!! A very PRECISE missile indeed!

[kussa]

The music is from the game Lineage 2, i think is from the load screen or the character selection screen.

lol if you get enough oxygen in there you could have a bomb, or cannon, or rocket :D

Did you get your deposit money back on your jug after this run LOL.....

[PernellDD]

I love the music, where can I find it? the video is so so... lol.
