American liquid rocket engine
TheRocketdyne S-3D (Air Force designationLR79 )[ 1] [ 2] liquid rocket engine produced byRocketdyne (a division of North American Aviation) between 1956 and 1961. It was a gas generator, pump-fed engine, using a liquid oxygen (LOX ) andRP-1 (kerosene) propellant combination, capable of producing 134,908 pounds of thrust (600.1 kN) at sea level.[ 3]
The S-3 was based on theRedstone engine,[ 4] [ 5] [ 6] [ 1] [ 2] PGM-19 Jupiter andPGM-17 Thor missiles,[ 7] [ 4] [ 8] Juno II rocket.[ 3] [ 9] [ 10] [ 11] XLR89-1 , MB-3-1, X-1, LR83-NA-1, H-1,LR89-5 ,XLR89-5 , S-3,LR89-7 , MB-3-J, MB-3, MB-3-3,RZ.2 , H-1c, H-1b,RS-27 ,RS-27A R ,RS-56-OBA andRS-27C .[ 5]
A second stage with four S-3 engines was considered for theSaturn A-2 study.[ 12]
