I want to build a quad pressure jet engine! But I'd try to go for a straight cut and not a perpendicular layout. But these are still fantastic. Have you got any blueprints? Also... Could you please be so kind as to tell me what music this is?
These engines aren't running at full power, also this must have been the maiden run of these two judging by the pretty color of that stainless correct? I don't think you'll see these babies run at their full potential however...Not to be an ass but I can tell proportions of the combustion chamber fore and aft of the 3rd stage are off. Plus that nose cone not being parabolic and at the proper proportions will inhibit proper wave propagation in these engines. Other than that nice build!
It's not a pulsejet at all. It may sound like one, but the principle of operation is completely different. Basically it's a ramjet that uses it's fuel to create the ram pressure rise.
It uses the high velocity of the incoming fuel to induce atmospheric air into the combustion chamber. The fuel is pre-heated first then sprayed at extremely high velocity into an air duct. This "drags" the air into the engine instead of sonic pulses or a mechanical compressor.
The compression (intake pressure) of these engines is actually formed from acoustic compression. The 2nd and 3rd stages of the intake ducted are sonically tuned to boost intake pressure.
would you care to try running these through a Y pipe?

I've got the plans for the helli. and the jets I should give those things a look at again!

OMG.. how long before the stainless steel melts to a blob ??

where's the turbine part? just 2 (nicely build btw) pressure jets
1metiz 2 years ago
@1metiz theres no turbine on these, because they are pulsejets. they operate on aerodynamic compression

@MrBobman360
I know so why does it say pressure jet turbine in the discription?

@1metiz good point hmm idk

I can`t see the turbine anywhere....

what is the difference to a normal pulsejet?
