METHOD FOR FORCING A DUAL-FLOW EJECTOR PULSE JET ENGINE AND FORCED DUAL-FLOW EJECTOR PULSE JET ENGINE Russian patent published in 2022 - IPC F02K7/67 

FIELD: engine building.

SUBSTANCE: group of inventions relates to equipment, primarily military, namely, to engines of aerial vehicles, and can be used, most likely, in engines of small unmanned aerial vehicles, such as surface-to-air, aviation, and tactical missiles, unmanned reconnaissance aircrafts, flying targets, etc. Forcing of a dual-flow ejector pulse jet engine (DFEPJE) consists in accelerating the combustion process by implementing the mechanism of oxidative methane pyrolysis forming acetylene. In order to implement the described process, coolable plates are installed in the second intake mixer pipe of the DFEPJE, and a coolable channel is installed in the back wall of the combustion chamber. Upon completion of the working cycle, burning gases containing methane, being cooled on the coolable plates and walls of the coolable channel, form acetylene further entering the combustion chamber at the suction cycle and causing acceleration of burning and growth of jet thrust.

EFFECT: claimed group of inventions allows for an increase in the jet thrust of the DFEPJE in the range of 15 to 20%.
