The high-pressure turbopumps are designed for use in the Space Shuttle's main engine. Together, a pair of turbopumps delivers liquid hydrogen and liquid oxygen to the shuttle engine's main combustion chamber for ignition. The discharge pressure for the fuel turbopump is 6,400 psi, while it is 7,250 psi for the oxidizer turbopump. The shaft horsepower is 72,900 hp for the fuel model and 25,850 for the oxidizer pump. Turbine inlet temperature for the fuel and oxidizer turbopump is 2,000 R and 1,700 R, respectively.
