This work depicts about the design of a valveless pulse mode combustor. Since the combustion process in a pulse jet engine occurs at a constant rate, a stepper motor running at that same rate should be able to open and close both valves at the right time. They have all the advantages (and most of the disadvantages) of conventional valved pulsejets, but without the reed valves that need frequent replacement - a valveless pulsejet can operate for its entire useful life with practically.
