Pulsejet Engine Vertical Launch - VTOL Pulse Jet Rocket

Pulsejet engine vertical launch - VTOL vertical take off and landing rocket

Pulsejet engines have been overlooked as a propulsion system because most people think they are low power and inefficient. Pulsejet engines actually have quite high power to weight ratios, comparable fuel consumption to RC turbines, and have few or no moving parts, meaning they cost about 1/10th as much as a hobby turbojet and rarely need any form of maintenance.

This is a video of an old demo we did, to show the potential of pulsejets. The engine is an old 1960's era dynajet, which is not anywhere near optimized, yet it still has impressive lift performance.

Sitting on the ground most people dont see the potential these engines have, and are content with saying they are useless, when that couldn't be further from the truth.

Pulsejets could be used on anything from RC hobby hovercrafts and RC VTOL planes, to small UAV's, and many other things.

the only problem with pulse jets in modern tech is that they get extremely hot on their outer surface, and are loud as hell.

[BeckTechnologies]

@cowsrock94 And rocket engines dont?

[magnum9987]

You should get gov't funding. Should be easy.

And couldn't you run two combustion chambers through a single exhaust like a Y-Pipe? And then time the pulses to coincide and use the venturi effect to get more thrust and efficiency?

[BeckTechnologies]

@magnum9987 You only get gov. funding if you give the politicians lots of $

[FireDropTechnologies]

Your forgetting heat exchange sir, when it hit's the air in your house it cool's drasticly. changing volume. That's why steam cars have a super heater befor the throughtle. But to use it in a combustion chambe of a rocket it only needs to hold super hot volume long enough to displace the air at the tail cone creating thrust, for a millisecond or two, then the rocket is past, and it can cool and shrick volume and no one will give a shit the rocket or you and I. And that 1400 volume at 0 preshure.

@FireDropTechnologies I'm gonna have to call BS, you quoted a volume expansion that could only occur in a vacuum pumped full of radiation, and are now googling you're way through steam references. Steam does not expand 5 million times in volume on earth, nor the vast majority of the universe.

@BeckTechnologies Think they could use that to put something in space? It would have to carry its own fuel and the payload... Which would probably mean lots of o2 for operation in a vacum. And Im not sure what that vibration would do to the payload while under the stresses of the atmosphere.

[MrMaxclip]

Could you also use it as a rocket engine in space?

[DynaDuctINC]

@BeckTechnologies But what about the Y pipe thing?

[arnold02000]

@BeckTechnologies True. Senators must be greased for favors, especially during election campaigns.

[TheNWONOW]

Install a gyroscope stabilization system and let that rip rip free air!

[cowsrock94]

@cowsrock94 I think theres a difference, the body of a pulse jet gets white hot and takes a long time to cool. it just looks like more of a burn hazard to me. And in my opinion rockets make a loud "whoosh" sound that doesn't have the same "oomf" as the noise from a pulse jet.

alright guys...it's time to go global and work as a community to get these innovations in the spotlight. our nations are way too busy trying to win a never-ending pissing contest...
