PULSE COMBUSTION CHAMBER FOR A SPACE ENGINE Russian patent published in 2021 - IPC F02K7/02 F02K7/06 

FIELD: aviation.

SUBSTANCE: invention relates to engine building, and more specifically to a pulse rocket engine. Disclosed is a pulse combustion chamber of a space rocket engine, containing an inlet check valve of a frontal device for fractional injection of an oxidizer, a swirler, a spark plug, a pulse fuel injector, an outlet check valve preventing the outflow of the fuel mixture from the combustion chamber when it is filled with a fuel mixture and at the beginning of combustion. The outlet check valve is installed at the outlet of the combustion chamber in front of the traction axisymmetric Laval nozzle and has a saddle with profiled passages, a plate with a stem and a return spring. The outlet check valve operates in a fully automatic mode and prevents the outflow of the fuel mixture into the surrounding space and increases the degree of additional pressure increase in the process of explosive combustion.

EFFECT: invention ensures that the fuel mixture is prevented from flowing out of the combustion chamber at the moment of its filling with combustion products and the additional degree of pressure increase increases.
