The pulse jet engine is a gas turbine characterized by an intermittent isochore combustion. The permanent flow of compressor output is pumped over in the form of gas bursts (pulses) towards the turbine stages after combustion has taken place in one or several units of three combustion chambers operating according to a three-phase cycle: intake, combustion, expansion. The throttle valves for opening and closing the chambers are controlled by electromagnets monitored by a digital system. The adjustment of the frequency of pulse productions and harmonization of the units enable the operating lines and variable permeability levels in the compressor field. The structural architecture is applicable to any type of aircraft engine, on land or at sea. For the same power level the pulse jet engine consumes less fuel, and the pumped over air flow is less than that of gas turbines. |
