DISK PUMP FEASIBILITY INVESTIGATION,
Abstract
The disk pump was investigated at the Air Force Rocket Propulsion Laboratory (AFRPL) to determine the feasibility of using a novel viscous pumping system as an inducer and/or mainstage pump for liquid rocket applications. This investigation consisted of the analysis, design, and test of a disk pump primarily for application as an inducer. The disk pump differs drastically from conventional pumps because of the following major factors: (1) The pumping action is a function of the viscous properties of the pumped fluid. (2) The pump does not require the conventional pump lifting forces. (3) The pump inlet relative velocity is equal only to the through flow velocity between the disks. Therefore, there is good indication that the disk pump will operate stably with excellent suction pump performance characteristics. The maximum suction specific speed reached was 55,400 in 70F water, with no apparent head deterioration. The representative maximum suction specific speed at a 3% head drop was never reached. The pump demonstrated unusual stability characteristics throughout all tests even at ultra low NPSH values of 4.7 ft. (Author)
