METHOD OF WITHDRAWING ROCKET CARRIER SEPARATED SECTION (RCSS) FROM PAY LOAD ORBIT AND POWER PLANT TO THIS END Russian patent published in 2010 - IPC F02K9/42 B64G1/26 

FIELD: engines and pumps.

SUBSTANCE: rocket carrier separated part (RCSS) is revolved about lengthwise axis to stabilise its angular position in space. Residual liquid fuel and oxidiser components are gasified to generate braking pulse by combusting them in gas rocket engine chamber and due to high-rate efflux of combustion products into space. Power plant (PP) comprises oxidiser and fuel tanks and tanks pressurisation system. PP additionally incorporates powder rocket engines to spin-up RCSS, at least, gas rocket engine with feed system and residual fuel-and-oxidiser gasification system. Said feed system comprise gas bleed devices incorporating pyro membranes connected to gas rocket engine manifold. Residual fuel-and-oxidiser gasification system comprises compressed gas cylinder, a ball, communicated via electropneumatic valve and reducing valve with fuel and oxidiser expansion tanks, and gas generator fed from said expansion tanks and communicated with devices to force gas into fuel tanks.

EFFECT: reduced contamination of outer space.
