TWO-CIRCUIT EJECTOR PULSATING AIR-JET ENGINE Russian patent published in 2021 - IPC F02K7/06 

FIELD: military equipment.

SUBSTANCE: invention relates to equipment, mainly to military equipment, namely to aircraft engines, and can be used, most likely, as an engine of small unmanned aerial vehicles, such as anti-aircraft, aviation and tactical missiles, unmanned reconnaissance aircraft, flying targets, etc. A two-circuit ejector pulsating air-jet engine (TEPuAJE) has a combustion chamber, a resonator tube, the first inlet mixing tube, in which an aerodynamic valve is installed, the second inlet mixing tube, a gas supply nozzle, a gas heating coil and a spark plug. The first inlet mixing tube is located inside the pipe of the combined air duct, hermetically fixed on the second inlet mixing tube adjacent to the end, which, in turn, is fixed on the front end wall of the combustion chamber. While a petal mechanical valve is installed inside the combined air duct at the entrance to the second inlet mixing tube.

EFFECT: increased thermodynamic efficiency is achieved by reducing unproductive fuel consumption.
