SOLID-PROPELLANT CHARGE FOR ENGINE Russian patent published in 2002 - IPC

Abstract RU 2178092 C2

FIELD: rocketry. SUBSTANCE: solid-propellant charge for rocket engine with star-like channel and cavities along generating lines on outer surface arranged on axes of symmetry of star-like channel projections is insert-type of all-round burning. Profile of charge channel sections between projections of star-like channel and outer surface between cavities are made with coinciding evolutes. Width of projections does not exceed thickness of charge burning arch. EFFECT: reduced discharge of digressive fuel remnants at end of engine operation, increased carrying capacity of combustion chamber in operation. 5 dwg
