EJECTION-VORTEX ENGINE Russian patent published in 2024 - IPC F02K7/67 

FIELD: machine building.

SUBSTANCE: invention relates to engine building, in particular, to air-jet engines (AJE), and can be used as power plant of aircraft, for example, unmanned aerial vehicle (UAV), as well as gas generator. Engine design includes: (1) - ignition plug, (2) - combustion chamber, (3) - gas-dynamic apparatus, (4) - vortex chamber - Ranque tube, (5) - ejector with adjustable nozzle throttle. Main unit of the engine is gas-dynamic apparatus (3). It consists of ejection-nozzle unit (6) and gas-dynamic diode (7) with supplied air and fuel lines (8). Design of ejection-nozzle apparatus includes hollow cooled blades (10) with cavity outlet to outer surface and outlet edge of blade, through which air is ejected and compressed by combustion products passing through gas path of ejection-nozzle apparatus from combustion chamber. Mixture of gases with intensive swirling, passing along the vortex chamber, is divided into cold and hot vortices, besides, the hot vortex enters the atmosphere through the controlled nozzle, and the cold vortex enters the combustion chamber through gas-dynamic diode (7).

EFFECT: efficiency of the AJE is increased due to a denser filling of the combustion chamber with a fuel-air mixture.
