RD-103

Glushko LOx/Alcohol rocket engine. R-5. Out of Production. 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.
