KS-50


Glushko Lox/Kerosene rocket engine. Experimental. Development 1948. Subscale versions of a radical new engine design. This featured a flat-plate injector, cylindrical combustion chamber, and a 60 atmosphere chamber pressure.

From 1947 the German team at Khimki was completing build of ten KS-59 'Lilliput' subscale versions of a radical new engine design. This featured a flat-plate injector, cylindrical combustion chamber, and a 60 atmosphere chamber pressure. The first engine was completed at the end of 1948. These were conceived by the Germans to test the design planned for the G-4/R-14. From the summer of 1949 to April 1950 100 tests were made of the engine. Although primarily intended to prove the use of Lox/Kerosene propellants, a wide range of propellants were tested, including exotic fluorine compounds and suspended beryllium hydride fuels. The Lilliput endured them all.

Application: Experimental.

Characteristics

Chamber Pressure: 61.00 bar.

Status: Development 1948.

Associated Propellants
  • Lox/Kerosene 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. In January 1953 Rocketdyne commenced the REAP program to develop a number of improvements to the engines being developed for the Navaho and Atlas missiles. Among these was development of a special grade of kerosene suitable for rocket engines. Prior to that any number of rocket propellants derived from petroleum had been used. Goddard had begun with gasoline, and there were experimental engines powered by kerosene, diesel oil, paint thinner, or jet fuel kerosene JP-4 or JP-5. The wide variance in physical properties among fuels of the same class led to the identification of narrow-range petroleum fractions, embodied in 1954 in the standard US kerosene rocket fuel RP-1, covered by Military Specification MIL-R-25576. In Russia, similar specifications were developed for kerosene under the specifications T-1 and RG-1. The Russians also developed a compound of unknown formulation in the 1980's known as 'Sintin', or synthetic kerosene. More...
