A turbopump is a propellant pump with two main components: a rotodynamic pump and a driving gas turbine, usually both mounted on the same shaft, or sometimes geared together. They were initially developed in Germany in the early 1940s.

Almost all existing rockets have centrifugal turbopumps. These deliver more ∆ P per stage than axial flow pumps, with only slightly less efficiency.

Mar 13, 2020 · In a liquid rocket engine, the pump avoids any type of cavitation while pumping, thus allowing high-density fluids to come inside at low inlet pressures. As soon as the high-density fluids start flowing in, the pump delivers them to its thrust chamber at excessively high pressure.

Dec 10, 2021 · Turbopumps help rockets achieve high power to weight ratio by feeding pressurized propellant to the rocket's combustion chamber. The success of rocket launch missions is heavily influenced by the design of inducers in the turbopumps.

rocket engine is a complete system in itself. It consists of many elements, some of which are themselves subsystems (e.g., pump and turbine). The turbopump consists of seven basic elements: 1) pump, 2) turbine, 3) bearings, 4) seals, 5) housings, 6) thrust piston, and 7) spline/couplings (Anon., 1974a).

Barber-Nichols (BN) has successfully developed the Propellant turbopumps for Virgin Orbit’s LauncherOne booster and upper stage liquid rocket engines, the 74,000lb f thrust NewtonThree and 4900lb f thrust NewtonFour.

This pump was used on the F-1 liquid fuel rocket engine, the powerplant for the first stage of the Saturn V launch vehicle that took the first astronauts to the Moon for six successful landing missions from 1969 to 1972 in the Project Apollo program. The F …

The liquid rocket engine turbopump is a unique piece of rotating machinery in comparison to turbo-jets, turbo-fans and turbo-props, since it is typically pumping cryogenic liquids while being driven by high temperature gases, posing large temperature differentials between …

The turbopump system, from preliminary design through rocket engine testing is examined. Selection of proper system type for each application and integration of the components into a working system are dealt with.

Developed in the 1970s by Marshall Space Flight Center in Huntsville, Ala., the Space Shuttle Main Engine is the world’s most sophisticated reusable rocket engine. NASA fuels discoveries that make the world smarter, healthier, and safer.
