F-1 Engine

85. Thrust chambers of the F-1 rocket engine on the manufacturing line.

Five F-1 engines powered the first stage of the Saturn 5 launch vehicle that launched the manned Apollo spacecraft to the Moon. These engines developed a total thrust of 3.5 million kilograms (7.6 million pounds). They burn liquid oxygen and a form of kerosene at a rate of 13,475 liters (3560 gallons) per second.

The propellants are supplied to the thrust chambers by turbopumps driven by gas generators that use a fuel-rich mixture ratio of the same propellants used in the engine.

The F-l was developed and produced by Rocketdyne, a division of Rockwell International, under the technical direction of the National Aeronautics and Space Administration, Marshall Space Flight Center, Huntsville. Alabama.

The engine on exhibit is from the National Aeronautics and Space Administration.
