The sign accompanying the injector. It reads


F-1 Engine Injector Plate

This piece from one of the first-stage engines of Apollo 11's Saturn V rocket was recovered from the bottom of the Atlantic Ocean in 2013.

The injector plate sprayed liquid oxygen and kerosene fuel into the combustion chamber. The propellants passed through the hundreds of small holes visible on the plate. The baffles protruding upward (bent by the force of the first stage crashing into the ocean) helped regulate the flow of the hot gases during the 2 1/2 minutes of combustion.

44 in. (111.8 cm) diameter; 1,200 pounds (544.3 kg)

Transferred from NASA


There are actually 1,428 oxidizer orifices and 1,404 fuel orifices on the injector, for a total of 2,832 propellant injection holes on the injector.
