Rocketdyne Lox/Alcohol rocket engine. Development cancelled 1955. Launch thrust 533.7 kN. Planned engine for the booster of the Navaho II test vehicle. Gas generator, pump-fed.
Thrust and specific impulse values are at sea level. Two would have been installed per booster. Cancelled in favor of a version of it burning kerosene instead of alcohol fuel, the LR-83.
Application: Navaho II booster.
Thrust (sl): 533.700 kN (119,981 lbf). Thrust (sl): 54,422 kgf.
Status: Development cancelled 1955..

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...
