An outstanding accomplishment by our space program. This is one of the best clips, up close, I have ever seen. If you guys have seen better please link me. The F-1 engine is a single-start, 1500000-pound fixed- thrust, bipropellant rocket system. The engine uses liquid oxygen as the oxidizer and RP-1 (kerosene as fuel. The engine is bell-shaped, with an area expansion ratio the ratio of the area of the throat to the base of 16:1. RP-1 and LOX are combined and burned in the engine's thrust chamber assembly. The burning gases are expelled through an expansion nozzle to produce thrust. The five-engine cluster used on the first stage of the Saturn V produces 7500000 pounds of thrust. All of the engines are identical with one exception. The four outboard engines gimbal; the center engine does not. The fuel pump supplies fuel to the thrust chamber and gas generator at a flowrate of 15471 gpm. The turbine, producing 55000 brake horsepower, drives the fuel and oxidizer pumps. It is a two-stage, velocity-compounded turbine consisting of two rotating impulse wheels separated by a set of stators. The turbine mounts on the fuel pump end of the turbopump so that the two elements of the turbopump having the greatest operating temperature extremes (1500 Fahrenheit for the turbine and -300 Fahrenheit for the oxidizer pump) are separated. Hot gas from the gas generator enters the turbine at a flowrate of 170 pounds per second through the inlet manifold and is directed through the first ...
