Rocketdyne F-1

The F -1 is a rocket engine, which was developed by the American manufacturer Rocketdyne. It was developed in response to a request of the U.S. Air Force in 1955 for a very powerful liquid rocket engine. The engine was eventually used in the first stage of the Saturn V rocket.

History

There were initially two designs. The E-1 has been tested, but not pursued because it harbored no technological potential. F- 1 should be operated with liquid oxygen, and RP -1. The development was initially stopped by the Air Force, because there is no need for such a powerful engine was seen.

However, the newly established NASA allowed the development to continue. The first complete test engine was fired in March 1959. The tests showed instability of the combustion process in the combustion chamber, which could be overcome through a lengthy development process, however. Except for the use in the first stage the Saturn V should be used in even greater Nova rocket.

On F- 1, a further development was made ​​during the 1960s. The so-called F -1A engine was easier and yielded 9.1 MN a 30% greater thrust. However, it was not used.
