The Redstone was a direct descendant of the German V-2 rocket, developed primarily by a team of German rocket engineers brought to the United States after World War II. The design used an upgraded engine from Rocketdyne that allowed the missile to carry the 6,900 lb (3,100 kg) W39 and its reentry vehicle to a range of about 175 miles (282 km).

The Redstone family of engines was the first large rocket engine produced by North American Aviation's Propulsion Section to enter service (the Propulsion Section would later become the Rocketdyne Division of North American Aviation).

The Redstone family of rockets consisted of a number of American ballistic missiles, sounding rockets and expendable launch vehicles operational during the 1950s and 1960s. The first member of the Redstone family was the PGM-11 Redstone missile, from which all subsequent variations of the Redstone were derived.

This is the Redstone rocket engine and was the U.S.'s first operational large-scale rocket engine. Development began in 1950 by North American Aviation. The engine used liquid oxygen and alcohol and developed 75,000 pounds of thrust.

2016年9月16日 · Derived from the Hermes C-1 project and building upon German experience with the V-2, the Redstone utilized the XLR43 engine from the Navaho project. The Redstone was designed as surface-to-surface ballistic missile with an original range of 500 miles that was later reduced to 200 miles.

The Redstone engine produced 77,200 pounds of thrust at liftoff utilizing a 780-horsepower turbopump with a precision cutoff mechanism. Trajectory was controlled by four vanes which were attached to four fixed fins at the base of the missile.

2016年7月8日 · Redstone was the first large liquid rocket developed in the US using German V-2 technology. Originally designated Hermes C. Redstones later launched the first US satellite and the first American astronaut into space. AKA: Hermes C;M8;M9;PGM-11;PGM-11A;PTM-11B;SSM-A-14;SSM-G-14. Status: Retired 1967. First Launch: 1953-08-20.

Its A-7 engine generated 334 kilonewtons (75,000 pounds-force) of thrust for 110 seconds burning the same combination of propellants used by the A-4 rocket: liquid oxygen and a mixture of 75% ethanol and 25% water.

This engine was the ancestor of all future North American Aviation (later Rocketdyne) engines. Thrust chamber and nozzle film cooling was achieved by fuel jets from the injector instead of the more complex rings of holes used on the V-2 engine.

The Redstone was powered by a Rocketdyne North American Aviation 75-100 A-7 engine gulping ethyl alcohol and liquid oxygen as its fuel of choice. This engine had a thrust of 350 kN and later engine iterations would see other fuel mixtures such as Hydyne.
