LIQUID ROCKET PROPULSION SYSTEM OF A SPACE VEHICLE Russian patent published in 2021 - IPC B64G1/00 

FIELD: engine building.

SUBSTANCE: invention relates to liquid rocket engines (LRE) on cryogenic components, equipped with an orientation and launching system (OLS). The OLS comprises blocks of low-thrust rocket engines (LTRE), electric pumps (1, 2) at the outlets of the low-pressure tanks of the cryogenic components, in communication with the receivers (8, 9) of the working fluid for the LTRE by pressure mains through gasifier heat exchangers (3, 4). The receivers are refilled by signals from the pressure sensors (11(1), 11(2)). The heat transfer paths of the gasifiers (3, 4) are in communication at the input with the main for high-temperature combustion products of the gas generator (5) and at the output with the exhaust nozzles (10(1), 10(2)) included in the structure of the LTRE blocks, the axes whereof are parallel to the longitudinal axis of the LRE. Output mains of the heat-receiving paths of the gasifiers (3, 4) are connected to the inputs of the gas generator (5) through electric valves (7(3), 7(4)).

EFFECT: reduction in the mass of the LRE structure with the maintained functionality of the OLS.
