Microcosm 356N

Microcosm Lox/Kerosene rocket engine. 356 kN. First stages. Hardware. Funded under AFRL SBIR Phase 1 contract of 2006. Ablative chamber, LOX/Jet A propellant engines designed for very low-cost, robust design margins.

In 2006 Microcosm began development of a new 356,000-newton engine under an AFRL SBIR Phase 1 contract. Both the 20,000-pound-force and 80,000 pound-force engines were follow-on developments to the successful 5,000-pound-force engines. All were ablative chamber, LOX/Jet A propellant engines designed for very low-cost, robust design margins, moderate chamber pressures, high reliability, and expendable applications.

Application: First stages.


Propellant Formulation: Lox/Jet A.

Status: Hardware.
Thrust: 356.00 kN (80,031 lbf).
First Launch: 2000-2004.

  • 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...
