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. http://rapidshare.com/files/299024703/Introduction_Of__Post_Combustion_Valve_in_Pulse_Jet.ppt"
