The Rocketdyne F-1 engine remains the most powerful single-nozzle liquid-fueled rocket engine ever flown. The F-1 burned RP-1 (rocket grade kerosene) as the fuel and used liquid oxygen (LOX) as the oxidizer.
A turbopump was used to inject fuel and oxygen into the combustion chamber. Each turbo pump was as powerful as a Boeing 747 engine and combined a turbine with seperate RP-1 and LOX pumps. The fuel pump was able to deliver 58,000 litres per minute while the oxidizer pump delivered 93,000 litres of LOX.
One notable challenge in the construction of the F-1 was regenerative cooling of the thrust chamber, facilitated by routing the fuel in pipes on the outside to absorb heat. And designed without the benefit of modern computer modelling techniques.
The overall launch capability of the Saturn V (which used 5 F-1 engines for the first stage) also remains unmatched as of 2024, although the Falcon Heavy has closed the gap.
