METHOD FOR BOOSTING DOUBLE-FLOW EJECTOR PULSATING AIR-JET ENGINE AND FORCED DOUBLE-FLOW EJECTOR PULSATING AIR-JET ENGINE Russian patent published in 2020 - IPC F02K7/67 

FIELD: military equipment.

SUBSTANCE: group of inventions relates to military equipment, particularly, to aircraft engines. Forcing of double-flow ejector pulsating air-jet engine consists in fuel supply to aerodynamic valve of the second circuit, its further jet mixing with fuel in combustion chamber and ignition. Supply of fuel to engine at suction cycle is performed simultaneously through two circuits of aerodynamic inlet valves – with further arrangement of intensive mixing in combustion chamber by jet blowing of combustion zone with formation of annular vortices. Besides, additionally braking of back emission of gases through inlet system is performed due to installation of triangular channel into the first mixer and annular shell at the inlet of the second mixer and return flow to resonator pipe due to performance of partial diffuser opening.

EFFECT: claimed group of inventions makes it possible to increase thermodynamic efficiency by increasing amplitude of pressure pulsations occurring at increase of volume of cyclic blowdown of combustion chamber.
