SOLID-PROPELLANT ROCKET ENGINE

摘要

FIELD: engines and pumps.SUBSTANCE: rocket engine comprises housing with front and rear bottoms and channel charge secured with cylindrical part with collars distributed at the ends. Front bottom mouth flange is secured to perforate barrel circular ledge, said barrel being composed by a hollow cylinder of incombustible material arranged coaxially in charge channel with clearance. Barrel length makes at least the axial distance from front bottom mouth flange to half the projection of front end uncoupled part on charge channel axis. Barrel wall depth decreases towards rear bottom side. Barrel perforation represents slit cut-outs located over its generating surface facing the charge and circular holes made at the level of behind-the-collar clearance extending to charge channel.EFFECT: decreased tear-off contact strains in propellant edge zones.4 cl, 2 dwg
