30,000-RPM Vane-Pump Demonstration

Abstract

An answer to the start-up problem involving the pivoting tips and the soft indium-lead-silver-plated cam surface was confirmed experimentally. Changes include antirotation stops on the vanes and a chamfer on the leading edge of the pivoting tip. Successful speed runs were conducted with the variable-displacement pump to 29,000 rpm, but were interrupted by bearing failures. The high-speed drive was redesigned to eliminate the cause of the bearing failures. Considerable progress has been achieved with electron-beam welding and lamination-wrapping studies in the program to evolve a technique for developing deformable cam rings.
