Investigation of a 30,000-RPM Turbine-Speed Hydraulic Pump.

摘要

The general objective of the research program was to develop technology for high-temperature hydraulic pumps capable of being directly driven at bleed-air or auxiliary-power-unit turbine speeds. The specific goal was a pressure-compensated hydraulic pump rated at 4000psi with a rated flow of 50gpm at 30,000rpm. The pump was to operate with a chlorinated silicone fluid with inlet temperatures to 600F. A two-lobed vane pump having pivoting-tip vanes, a deformable cam ring,and rotor length approximately twice rotor diameter was the concept selected for development. (Author)
