ROCKET CRYOGENIC STAGE (VERSIONS) Russian patent published in 2005 - IPC

Abstract RU 2247063 C2

FIELD: rocketry and space engineering; cryogenic stages of space rockets.

SUBSTANCE: according for first version, oxidizer supply unit is shifted in transversal direction and is secured in lower point of convex part of lower head plate of oxidizer tank, thus forming additional space in inter-tank compartment in axial direction; this space is used for displacement of cruise engine together with fuel tank towards oxidizer tank. According to second version, oxidizer supply unit is secured on concave part of lower head plate of oxidizer tank. Full suction of oxidizer from tank is performed by means of passages of intake unit introduced into concave part of lower head plate of oxidizer tank and used for coupling the lower zone of oxidizer tank with oxidizer supply unit inlet.

EFFECT: improved mass characteristics due to reduction of overall dimensions in length.
