    Rocket Engine, Liquid Fuel, Jupiter Missile

    Tubular at top of combustion chamber with large bell-shaped nozzle flaring out below and pumps and other plumbing joined to the top of the chamber and thrust mounting. The engine also features regenerative-cooling through the "spaghetti" configuration in which the cooling tubes form the longitudinal walls of the chamber thereby both strengthening the chamber as well as cooling it with the flow of fuel prior to injection. A series of horizontal bands further strengthen the chamber.

Shown here is the S-3 engine that powered the U.S. Army's Jupiter intermediate range ballistic missile (IRBM), the first missile of its type put into service by the United States. Developed and built by the Rocketdyne division of North American Aviation, the S-3 was a modified version of the engine that powered the Army's Redstone missile. The S-3 used liquid oxygen to burn the RP-1 fuel, a type of kerosene. During flight, the engine burned for 178 seconds and produced a thrust of 150,000 pounds.

NASA transferred this engine to the Museum in 1966.
