NASA/SP-8109, NASA SPACE VEHICLE DESIGN CRITERIA (CHEMICAL PROPULSION): LIQUID ROCKET ENGINE CENTRIFUGAL FLOW TURBOPUMPS (DEC-1973)

NASA/SP-8109, NASA SPACE VEHICLE DESIGN CRITERIA (CHEMICAL PROPULSION): LIQUID ROCKET ENGINE CENTRIFUGAL FLOW TURBOPUMPS (DEC-1973)., Design criteria and recommended practices are discussed for the following configurations selected from the design sequence of a liquid rocket engine centrifugal flow turbopump: (1) pump performance including speed, efficiency, and flow range; (2) impeller; (3) housing; and (4) thrust balance system. Hydrodynamic, structural, and mechanical problems are addressed for the achievement of required pump performance within the constraints imposed by the engine/turbopump system. Materials and fabrication specifications are also discussed.
