Abstract
Higher pump speeds and pressures with the consequent increase in output per pound is the surest way to meet the reduced pump weight required in future gas turbine engines (1).* This paper discusses problems associated with operating pumps at engine shaft speeds or on drives independent of the engine. Mechanical and hydraulic problems related to different fluids, contamination, and minimization of fluid temperature rise are covered.
In some recent engines, pumps have been operated successfully at higher speeds and pressures. Current pump speeds, however, are still far short of the smaller gas turbine shaft speeds.
The paper covers the present state-of-the-art, current development programs, and a projection of future developments toward higher pump speeds.
