Ames Mach 10 Demonstrator

American manned spaceplane. Study 1957. Ames proposed in 1957 to air-launch a high-wing designed hypersonic glider from a B-36 bomber. Early versions would use an XLR-99-powered booster stage and be capable of reaching Mach 6.

The final version would be powered by a 68,000 kgf LR-89-NA-1 engine and reach Mach 10. The aircraft would be launched over the Atlantic Ocean off Cape Canaveral and then fly across the southern United States for a landing at Edward AFB in California.

Gross mass: 68,000 kg (149,000 lb).

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...
