Laser Velocimeter Axial Plane Data Reduction computer program computes circumferentially averaged velocities, total pressures, and other flow quantities from laser-velocimeter measurements in turbopump.
Slanted radial slots at tandem positions along approximate streamlines incorporated into swept inducer blades in turbopump, according to proposal. With suitable design, slots suppress low-frequency oscillations induced by cavitation, without causing excessive loss of inducer head. Slots cut into solid blades by wire electrical-discharge machining.
Brief report proposes use of jet boost pumps in conjunction with main pumps supplying liquid hydrogen and liquid oxygen to main engine of Space Shuttle. Main part of pump has no moving parts. Benefits include increased reliability, simplified ducts, and decreased weight.
