  • Kestrel SpaceX Lox/Kerosene rocket engine. 30.7 kN. Upper stages. Hardware. Isp=320s. Pintle architecture, designed to be a high efficiency, low pressure vacuum engine. Fed only by tank pressure, ablatively cooled First flight 2006. More...

Associated Launch Vehicles
  • Falcon 1e Version of Falcon 1 with stretched first stage and much more powerful Merlin engine. More...
  • Falcon 1 American low cost orbital launch vehicle. Falcon I was a two stage, reusable, liquid oxygen and kerosene powered launch vehicle. A single engine powered the first stage. It was designed for cost-efficient and reliable transport of satellites to low Earth orbit. First launch of the Falcon I was scheduled for mid-2004 from Vandenberg, carrying a US Defense Department communications satellite. Development delays and problems with USAF clearances for launch from Vandenberg resulted in the first launch attempt being made in 2006 from a private facility at Omelek near Kwajalein atoll in the Pacific. Success was achieved on the fourth launch in 2008. The Falcon 1 was to be superseded by the Falcon 1e, with an extended-tank first stage, from 2010. More...

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...
