The Apollo Saturn V-F1 engine was developed by Rocketdyne, and to this day remains one of the, if not, the most powerful single combustion chamber liquid-propellant rocket engine ever developed. This beast of an engine, in its later up-rated version, produced over 1.5 million lbs of thrust.

Five F-1 engines were used in the S-IC first stage of each Saturn V, and each one consumed a staggering 3 metric tons of fuel & oxidiser per second. Sixty-five F-1 engines were launched aboard thirteen Saturn Vs, and no flight failures were recorded making it an ultra-reliable part of the programme.

The turbo pump was the unit that supplied the thirsty engine with the propellant which comprised of fuel and oxidiser at the rates required to produce the prodigious amount of power. The propellant consumption for each engine was a mind boggling 3 metric tons per second. The 3 tons were made up of 2 tons of fuel (RP-1 which is a highly refined Kerosene), and 1 ton of oxidiser (liquid oxygen), Bearing in mind there were five of these engines working in tandem meant that a staggering 15 tons per second was consumed, and this was maintained for 2.5 minutes The pump was driven by burning an amount of the fuel and oxidiser, these hot gases spun an impellor fixed to the middle of a shaft, attached at either end were impellors. These two impellors were responsible for pumping each the fuel and oxidiser. The shaft spun at 5,500 RPM and generated 55,000 brake horsepower (41 MW).

The lox inducer fairing cap is a domed aluminium casting that was fixed over the nut that held the impellor to the shaft. It was there to smooth the flow of liquid oxygen as it entered the impellor. The cap in the collection is a used item that was removed from a test engine that had been hot-fired on numerous occasions.
