DEVICE FOR DISCHARGE OF GAS FROM ROCKET CRYOGENIC STAGE (VERSIONS) Russian patent published in 2006 - IPC B64G1/52 F17D1/04 F16L3/01

Abstract RU 2290354 C2

FIELD: rocketry and space engineering; devices for discharge of gas from cryogenic stages.

SUBSTANCE: proposed device has two pipes interconnected by means of adapter. According to first version, adapter of these pipes is secured on inter-tank truss of rocket cryogenic stage. Free end of each pipe is secured on said inter-tank truss by means of support which includes cylindrical guide with adapter member arranged inside it. According to second version, adapter of pipes is secured on lower bottom of oxidizer tank of rocket cryogenic stage. Each pipe is provided with angular displacement compensator. Free end of each pipe is secured on inter-tank truss by means of support which has pin with sphere and limiter. Pin sphere is received by passage of pipe adapter member. Axis of adapter member passage is perpendicular to longitudinal axis of adapter member.

EFFECT: reduction of relative displacement of attachment areas; reduction of mass.
