Glushko Lox/Alcohol rocket engine. 500 kN. R-5. Out of Production. Isp=243s. Final extrapolation of the V-2 rocket engine in Russia. First flight 1953.
Designer at OKB-456 was V A Vitkin. Glushko states 'thus ended the German page' of German engine technology in the USSR (this ignores the fact that the German ED-140 design provided the basis for the entire next generation of Soviet rocket engines). The engine introduced automatic thrust regulation in flight, a feature first advocated by Groettrup's German team for the G-1 engine.
Thrust (sl): 432.000 kN (97,117 lbf). Thrust (sl): 44,000 kgf. Engine: 870 kg (1,910 lb). Chamber Pressure: 23.90 bar. Propellant Formulation: Lox/Alcohol-92%. Thrust to Weight Ratio: 58.62.
AKA: 8D71; RD-103; 8D52.

Lox/Alcohol Liquid oxygen was the earliest, cheapest, safest, and eventually the preferred oxidiser for large space launchers. Its main drawback is that it is moderately cryogenic, and therefore not suitable for military uses where storage of the fuelled missile and quick launch are required. Alcohol (C2H5OH) was the fuel used for the German V-2 rocket, and the first derivative rocket engines in the United States, Soviet Union, and China used it as well. Better performance was achieved by increasing the alcohol concentration in the post-war engines. But after better-performance rocket-grade kerosene was developed by Rocketdyne in the REAP program of 1953, use of alcohol was abandoned. More...
