Re: Variable frequency valveless pulsejet

Your best bet is to go with a thermojet I think, because you can realy abuse those and they'll keep running. You can change frequency by one, or a combination of, the following (some are already mentioned above): Make the exhaust tube variable in length; Make the intake(s) variable in length; Make ...

Variable frequency valveless pulsejet

I'm assessing the feasibility of the following: A "valveless" pulse jet that can run at several discrete pulse-per-minute rates, in a range from 110hz to 220hz, or 220hz to 440hz, understanding that the operational frequency changes with the engine temperature. This is a boondoggle, by the way. I am...

I'm assessing the feasibility of the following: A "valveless" pulse jet that can run at several discrete pulse-per-minute rates. It doesn't have to fly, so weight, aerodynamics, and thrust ar...
