METHOD FOR BOOSTING DOUBLE-FLOW EJECTOR PULSATING AIR-JET ENGINE AND FORCED DOUBLE-FLOW EJECTOR PULSATING AIR-JET ENGINE Russian patent published in 2021 - IPC F02K7/02 F02K7/67 

FIELD: military equipment.

SUBSTANCE: invention relates to military equipment, in particular to aircraft jet engines and can be used as rocket engines or unmanned aerial vehicles. Forcing a two-circuit ejector pulsating air-jet engine (TCEPuAJE) consists in accelerating the combustion process due to the preliminary implementation of the mechanism of pyrolysis of the initial working fuel of gasoline into propane, butane, ethylene and methane and then with the formation of acetylene from them. To implement this process, behind the fuel coil 6 for heating the fuel, outside the TCEPuAJE, a steam-air heat exchanger 7 is installed or a partial supply of fuel 9 to the fuel manifold 8 is carried out, leading to a sharp drop in the temperature of the fuel vapor and the release of acetylene. Acetylene in the resulting gas mixture, entering the combustion chamber of the TCEPuAJE, accelerates the combustion process, which leads to an increase in the amplitude of pulsations of the specific and frontal thrust.

EFFECT: invention allows to ensure a doubling of the specific and frontal thrust of the TCEPuAJE.
