F-1 Turbo Pump Gas Generator
For small, liquid-fuel rocket engines, the pressurization of the fuel and
oxidizer tanks may be sufficient to feed the propellants into the combustion
chamber. This wasn't the case for the mighty F-1. It devoured propellants so
rapidly, another mechanism was needed to satisfy its appetite.
MSFC and Rocketdyne developed a turbo pump to force propellants into the F-1's
combustion chamber at a high rate (about three tons per second!). The turbo
pump machinery was driven by a gas generator – essentially another
rocket engine producing approx. 60,000 horsepower – mounted externally on the
F-1's main thrust chamber.
The sample on display is a piece of an injector plate from an F-1 turbo pump.
