SOLID-PROPELLANT ROCKET ENGINE Russian patent published in 2004 - IPC

Abstract RU 2221159 C2

FIELD: rocketry. SUBSTANCE: proposed solid- propellant rocket engine contains nozzle unit and combustion chamber accommodating channel charge burning over outer surface and channel. Projections are made on inner surface of combustion chamber over its length. Projections are located in middle and/or rear of combustion chamber. Bushing of noncombustible material rigidly connected to surface of charge channel is fitted in channel of charge from side of front end face. EFFECT: improved weight characteristics of engine owing to reduction of thickness of combustion chamber wall, improved reliability of engine owing to increase of strength margin of combustion chamber. 4 cl, 1 dwg
