PULSED TURBOJET ENGINE Russian patent published in 2018 - IPC F02C5/12 

FIELD: engines and pumps.

SUBSTANCE: pulsating turbojet engine is equipped with the inlet diffuser, compressor, gas turbine, output jet nozzle and the pulsating combustion chambers block, direct current electric motor with the gearbox. Pulsating combustion chambers block contains stationary horizontal pulsating combustion chambers, two rotating valve discs. Combustion chambers are equipped with the air inlet and gas outlet openings. Rotating valve discs are connected by the common shaft, the first of them, installed in front of the combustion chambers, has air, and the second one, installed behind the combustion chambers, has gas openings. Valve discs axes coincide with the combustion chambers block horizontal axis. Combustion chambers block contains located around this block circumference four pulsating combustion chambers, with angles between the combustion chambers radial axes equal to 90°. First valve disc has four air holes, which radial axes are located at angles of 45°, 135°, 225° and 315°. Second valve disc has four gas holes, which radial axes are located at angles of 0°, 90°, 180° and 270° relative to the combustion chambers block central vertical axis.

EFFECT: invention allows to increase the pulsating turbojet engine power, jet thrust, efficiency and reliability.
