METHOD OF PULSE JET ENGINE DOUBLE-FLOW BLOWING AND DOUBLE-FLOW PULSE JET ENGINE Russian patent published in 2017 - IPC F02K7/06 F02K7/67 

FIELD: engines and pumps.

SUBSTANCE: method of pulse jet engine double-loop blowing consists in air supply through valve, its subsequent mixing with fuel and ignition. Pulse jet engine blowing at suction cycle is performed simultaneously via two circuits of different-type inlet valves, aerodynamic and mechanical, with subsequent arrangement of intensive mixing in combustion chamber by means of combustion zone jet blowing with formation of annular vortices. Besides, additionally performing blowing towards gas jet main flow from ejector prechamber, located at combustion chamber end wall. Double-flow pulse jet engine comprises combustion chamber, resonator pipe, inlet pipes, gas supply nozzle, gas heating coil and ignition plug. Combustion chamber front wall is made with mechanical lamellar valve. Combustion chamber rear end wall is made with ejector prechamber.

EFFECT: invention allows increasing thermodynamic efficiency by increasing pressure pulsations amplitude, occurring with increase in volume of combustion chamber cyclic blowing.
