ROCKET CRYOGENIC STAGE Russian patent published in 2005 - IPC

Abstract RU 2250861 C2

FIELD: rocketry and space engineering; upper stages of launch vehicles injecting payloads from reference orbit into working orbits.

SUBSTANCE: proposed cryogenic stage includes cruise engine, oxidizer tank, toroidal fuel tank, inter-tank compartment, truss for connection with payload and truss for connection with launch vehicle. Toroidal fuel tank is made in form of lens in cross section with bottoms changing to frames. Tank is coupled with said trusses and inter-tank compartment through outer frame forming load-bearing system for taking-up external inertial loads.

EFFECT: reduction of total longitudinal clearance and mass of cryogenic stage; increased zone of payload under launch vehicle fairing.
