Advanced Thermalpulse "Chinese" Valveless Pulsejet Engine

Check out our new website at http://www.PulseJetEngines.com Advanced chinese-style valveless pulsejet engine, running on propane, it gets so hot that the stainless steel starts to burn!

A valveless pulsejet is a type of jet engine with no moving parts. It can run statically and be throttled over a wide range. Unlike turbojet / turbine engines they do not have any spool up time, and can be throttled to back and forth from minimum to maximum throttle many times a second.

While they do get extremely hot, they are surprisingly efficient compared to hobby RC turbine engines. Pulsejets have no moving parts, and they use sound waves to compress the fuel air mixture. This natural compression is very efficient, compared to mechanical compression of turbines and turbojets. Because of this a good valveless engine will actually be more fuel efficient than the average hobby turbine, and if you use a thrust augmenter duct with the pulsejet, the efficiency can easily jump to twice that of a turbine.

When you combine this, with the fact that they have no moving parts, require no complex precision machining required by extremely high RPM parts, you have a very attractive engine, that costs 10 times less than a cheap hobby turbine. No moving parts also means no real maintenance.

Hobby turbines should be taken apart and inspected each run, and many parts like the bearings need frequent replacement, most hobby turbines need a complete overhaul of all moving parts after 20 hours.

For not much more than the cost of a ducted fan system, you can have your own real high speed jet, for a tiny fraction of the cost of a RC turbine engine alone.

these engines where designed in germany during the second world war you fuckwit not america

[BeckTechnologies]

@willa5000 Nope. This engine along with the rest of the engines on this channel were designed and built in America.

[Helge129]

@BeckTechnologies Comprehension fail. He's saying Pulsejets as in the technology behind them were invented in Germany, not the engines on your channel.

[BeckTechnologies]

@Helge129 Its pretty clearly stated in multiple places that these engines are designed and built in America, and though the Germans designed and built many in WWII thats not where they were originally invented.

[Helge129]

@BeckTechnologies Russians actually invented them I just found out, not Germans, but the Germans were the first to actively use it. America had nothing to do with the invention of the Pulsejet.

[BeckTechnologies]

@Helge129 You're still forgetting that this started because some ignorant fool went off about how pulsejets weren't invented in America, which they were never claimed to be. The engines on this channel were DESIGNED and BUILT in America, by an American, although an American of German descent. The automobile may have been invented in Europe, but obviously not all cars are European.

[BeckTechnologies]

@JC4crs There are other countries that call themselves the United States, before you go on a power trip maybe you should do some reading. If we all agree America is a land mass, then how is saying "made in america" any different than saying "made in europe" or "made in asia" considering its distinguishing two different land masses on opposite sides of the planet. I look forward to you response as soon as the bus drops you off from school.

was this not the type of jet used in the greman v1-buzz bombs?

[jordanherrmann]

So... It was made in china? haha. riddle: how tall is a chinese man? .... yes he is. haha get it? how tall. Like How Tall. That's his name. He's a chinese man. Get it? How long is a china man :D how mean is a china man? hahaha I crack myself up. Cool. I've yet to seen a video of this powering anything realistic.

[mrbishi1000]

@BeckTechnologies I get it, not as thick as some, nice jet aye:)

[programme1111]

@Lucifer9387 Ahhh nope...

[Lucifer9387]

@programme1111 You really think $5 will cover the hospital bill?..

[1stap02]

Thanks, that video was really quiet

[mexburnning]

beautiful colors.



[programme1111]

$5 to touch it

[llorttaf]

@XStarss Valveless pulse jets have no "membrane"...hence the "valveless"

[XStarss]

Pulse jet is not interesting to me, it has short life because of intake membrane, and low performance, i recomend you building turbo jet engine, it is not hard at all, almost all parts you can take out of turbo charger which you can remove from some car in scrap yard for free or small fee.
