MULTI-UNION DETACHABLE UNIT Russian patent published in 1999 - IPC

FIELD: manufacture of rockets. SUBSTANCE: unit includes on-board and ground plates with filling mains fastened by locking members, as well as separation mechanisms and drive. It is additionally provided with electrical connectors. Unions and electrical connectors are located symmetrically relative to central union. Ground part of central union is spring-loaded and is movable relative to ground plate in axial direction in uncoupled state by amount of stroke of uncoupling of other unions. head of central union is engageable with seal being collapsed over spherical surface. Force of spring in coupled opposition is more than or equal to uncoupling force. Tightness of other joints is ensured by seals over cylindrical surfaces. EFFECT: possibility of automatic coupling/uncoupling of filling mains and electric lines in case of reduced power action on flying vehicle at start.
