History

The Rocketdyne-developed F-1 engine was the world's largest liquid fueled rocket engine. The F-1 was originally developed by Rocketdyne to meet a 1955 US Air Force requirement for a new very large rocket engine. The eventual result of that requirement was two different engines—the E-1 and the much larger F-1. The E-1, although successfully tested in static firing, was quickly seen as a technological dead-end and was abandoned for the larger and more powerful F-1. The USAF eventually halted research and development of the F-1 due to a perceived lack of requirement for such a large engine. However the recently created NASA realised the capability afforded by an engine with so much power and contracted Rocketdyne to complete the development of the F-1. The first static firing of a full stage developmental F-1 was performed in March 1959. (Earlier test firings of F-1 components had been performed as early as 1957.)

Early F-1 tests revealed serious combustion stability problems (mostly concerned with the design of the fuel injector plate) which led to a number of engine tests failing due to either engine flame-outs or rapid explosive combustion. These problems were addressed throughout 1959 and the next couple of years and eventually the engine's combustion was so stable that a bomb could be detonated inside a firing engine with no issues.

The F-1 burned two short tons (1.8 t) of liquid oxygen (LOX) and one ton (0.9 t) of RP-1 (kerosene) each second generating over 1.5 million pounds-force (6.7 meganewtons) of thrust. Five F-1 engines were used in the S-IC first stage of the U.S. Saturn V rocket. During their two and one-half minutes of operation, the 5 F-1s propelled the Saturn-V vehicle to a height of 52 km (32 miles) and a speed of 8,700 km/h (5,400 mi/h).

There were proposals to use eight F-1 engines on the first stage of the Nova rocket.

F-1 Developments

There was an uprating redevelopment of the F-1 undertaken by Rocketdyne during the 1960s which resulted in a new engine specification known as the F-1A. While outwardly appearing to be very similar to the F-1, the F-1A was actually lighter and yet significantly more powerful (9.1 MN compared to F-1's 6.7 MN) and would have been used on future Saturn V vehicles in the post-Apollo era. However, the Saturn V production line was closed prior to the end of Project Apollo and no F-1A engine ever flew on a launch vehicle.

The F-1 engine remains the most powerful liquid fuel rocket engine ever developed at 6.7 MN of thrust. However among solid-fuel engines, more powerful engines exist such as the Space Shuttle Solid Rocket Boosters, which each boast a thrust of 14.7 MN.
