Korolev LOx/Kerosene rocket engine family. High-performance upper-stage engine developed for N1 lunar crasher stage, but saw general use as restartable Block D upper stage of Proton launch vehicle. First flight 1967. Also proposed for N12RA, Proryv, LM, 315GK for Zenit, Angara, Energia-M.
Kerosene changed from T-1 to RG-1 to achieve sufficient chamber cooling.
Engine: 300 kg (660 lb). Chamber Pressure: 78.00 bar. Area Ratio: 189. Propellant Formulation: Lox/RG-1. Thrust to Weight Ratio: 28.33.
