TRANSPORTATION SPACE SYSTEM Russian patent published in 2001 - IPC

FIELD: rocketry and space engineering; single-stage facilities for injection of payloads into Earth satellite orbit. SUBSTANCE: system includes payload bay and launch vehicle arranged in tandem. Launch vehicle is provided with liquid-propellant engine plant with central body and modular combustion chambers which are secured on the outside of bearer frame inside fairings which are mounted at spaced relation to central body. Gaseous hydrogen rings heated to high temperature are admitted to active leg into external atmosphere from combustion chambers (from screen of their internal cooling). Excessive hydrogen is burnt finally in incoming flow of air where fairing with chambers are introduced. EFFECT: increased specific impulse of lox/liquid hydrogen engines; increased mass of payload. 5 dwg, 1 tbl
