Part of an axial turbopump designed and built for the M-1 rocket engine. 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.

2021年12月10日 · 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.

2020年3月13日 · There are two ways in which liquid rocket engines work: either with pump feeding or with pressure feeding. The variant you choose depends on the purpose for which you are using the engine. For example, if you work on a project that requires low payload and low velocity, the turbopump will feed propellants into the thrust chamber by pressurizing ...

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

Here at NASA Glenn Research Center, as the starting phase of a rocket engine design, specifically a Nuclear Thermal Rocket Engine design, we adopted the approach of using a high level system cycle analysis code (NESS) to obtain an initial analysis of the operational characteristics of a turbopump required in the propulsion system.

2024年7月29日 · A rocket engine turbopump receives liquid propellants from vehicle tanks at relatively low pressure and supplies the same to its combustion chamber at a specific injection pressure and flow rate....

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. Details are also given on the design of various components including inducers, pumps, turbines, gears, and bearings.

The function of the rocket engine turbopump is to receive the liquid propellants from the vehicle tanks at low pressure and supply them to the combustion chamber at the required flow rate and injection pressure.

High speed propulsion employing turbojets, turbofans and variable cycle engines is interpreted here as propulsion for supersonic air vehicles with flight Mach numbers up to the technical limits of the gas turbine. This limit is somewhere between flight Mach numbers of 3 to 4.

Space Shuttle Main Engine Turbopump 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. In 1983, NASA began undertaking major improve-
