Pulse Jet engine - A new design concept!

[aryanscarlet]

I`ve had a new idea in designing a pulse jet by adding a valve in it... According to my intuition and logically this increases the output many folds and I`ve given sufficient reasons for suggesting it. I have a powerpoint of my idea that I have made and I request any of you to please go through it and suggest whether it is viable or not!

Thank you.

Many years ago, a friend of mine tested a ram-jet (I think a type of pulse jet) in his garage. I could hear it from two miles away. Are you talking about a silent pulse-jet?

It wasn't a ramjet unless his garage was traveling at supersonic speeds.

Must have been a pulse detonation jet. See
http://en.wikipedia.org/wiki/Jet_engine#Types
I know we had to start the engine with applied compressed air and (maybe) continuous spark plug ingition. Both the pulse jet and the pulse detonation jet are described in the above URL as "extremely noisy". What the world needs is a silent jet engine.

My point is sirs, that it is already used only in very few applications like military and experimental applications. I know pulse jets are noisy! I just say that my project can increase its efficiency and so it will still continue to be used in missiles etc where it is already been used, just with better efficiency and higher thrust.

I need to know if my project is workable or not??? Will it work???


Please help me! May be some CFD analysis would give us the result but I don know how to do it. If any of you know how to do one, I beg you all to just give it a try. That's the only thing that is making my project weak. You can have the dimensions of the existing pulsejet from something called Pulsejet calculator 1.4. Its an xl file you can get just by a google search!

Please try it!

Believe it or not, pulse jets and pulse detonation engines are still an active area of research. I know of one program in particular.

I'm aware of research going on! I want you to please download my presentation and review my project idea. Please tell me if its feasible or not! :confused:
