IT WORKS ... :wink: :lol: This concept was at the base of Conceotion GLC PHS system, and trust me, we would not have sold any units if the concept would not have worked with...

Re: Cutting noise

Mike, Yes, sound and pressure synonymous. To this I ask, what drives mass acceleration? Why would we see peak +pressures near 30 psi in the CC and only +5 psi at the tail openings, dumping out as an overpressure? what happened to that other +25 psi? luc, Ok, got it i think. What would we like to se...

Re: Cutting noise

I think I can help illustrate what luc is talking about in a general sense with the attached illustration of basic methods. What got me deep into pulse-jets in the first place was the seeming impossibility of removing the noise from the pulsejet. Any way you care to look at it, you can't separate "...

Re: Cutting noise

We probably have our wires crossed so lets look at the example to clarify. I think this is what you had proposed a 1" pipe within a 2" pipe, each at 24" length and each with a closed end? Are the capped ends in the correct configuration? Nope ... Flip the 2" diameter tube to other way around ... :w...

Re: Cutting noise

That would reduce the pressure somewhere, pressure that was developed at the cost of fuel Nope ... Not at all ... When I say "Reaches the tail pipe", I mean "Reaches the Tail Pipe Outlet " and at this point, you have ALL the "Pressure" you could get from that "Fuel" and you're now back to "Ambient"...
