The F-1 is a rocket engine developed by Rocketdyne. The engine uses a gas-generator cycle developed in the United States in the late 1950s and was used in the Saturn V rocket in the 1960s and early 1970s. Five F-1 engines were used in the S-IC first stage of each Saturn V, which served as the main launch vehicle of the Apollo program.
Dynetics and Aerojet Rocketdyne (AJR) also offered their AR1 hydrocarbon-fueled rocket engine as replacement of the RD-180. [ 21 ] [ 22 ] ULA CEO Tory Bruno said in early 2015 that both the AR-1 option and the US manufacture of the RD-180 by ULA under license were backup options to the primary option ULA was pursuing with the Blue Origin BE-4 ...

After World War II, North American Aviation (NAA) was contracted by the Defense Department to study the German V-2 missile and adapt its engine to Society of Automotive Engineers (SAE) measurements and U.S. construction details.

The F-1 engine was five years into its development at the time and still experiencing combustion stability problems. Rocketdyne eventually solved the F-1 instability problems by adding copper dividers as baffles, [15] but the RD-270 still had unsolved instability problems when the N1 program was cancelled in 1974, long after the F-1 problems ...
While tripropellant engines have been tested by Rocketdyne and NPO Energomash, no tripropellant rocket has been flown. There are two different kinds of tripropellant rockets. One is a rocket engine which mixes three separate streams of propellants, burning all three propellants simultaneously.
Pogo oscillation is a self-excited vibration in liquid-propellant rocket engines caused by combustion instability. [1] The unstable combustion results in variations of engine thrust, causing variations of acceleration on the vehicle's flexible structure, which in turn cause variations in propellant pressure and flow rate, closing the self-excitation cycle.
