ENGINE Russian patent published in 2018 - IPC F02K9/78 F02C7/08 

FIELD: engines and pumps.

SUBSTANCE: invention relates to an engine used in the aerospace field. Engine contains rocket combustion chamber for combustion of fuel and oxidant, an air-reactive combustion chamber for the combustion of fuel and oxidant, an air compressor to create air pressure for supply to the air-jet combustion chamber, the first fuel supply system to supply fuel to the rocket combustion chamber, the second fuel supply system for supplying fuel to the air-jet combustion chamber, the oxidizer supply system for supplying the oxidant to the rocket combustion chamber, the air-reactive combustion chamber and the rocket combustion chamber are made with the possibility of independent operation, the specified engine is made with the ability to switch from air-jet mode in full rocket mode, the engine further comprises a first heat exchanger device having an inlet and outlet installed to cool the air supplied to the compressor using a heat transfer medium, before being compressed by the compressor, heat transfer medium circuit for heat transfer medium, the second device of the heat exchanger, made with the possibility of cooling the heat transfer medium due to the fuel supplied by the first or second fuel supply system. Method of operating the engine, as well as the aircraft, is considered.

EFFECT: invention provides increased performance of a rocket engine, increased payload and fuel economy.
