ANALYTICAL INVESTIGATION OF THE EFFECT OF TURBOPUMP DESIGN ON GROSS-WEIGHT CHARACTERISTICS OF A HYDROGEN-PROPELLED NUCLEAR ROCKET

Axial-flow, mixed-flow, and centrifugal pumps driven by single- and twin- turbine drive systems were investigated for application in a high-pressure bleedtype turbopump unit. The effects of turbopump weight and turbine flow rate required for each type are shown in terms of the ratio of rocket gross weight to payload for a fixed mission (auth)
