Abstract : The purpose of this hydraulic-pump technology-development project was to investigate the feasibility and applicability and to demonstrate the capability of new vane-pump concepts to meet future aircraft hydraulic-system requirements. The specific objective was the development of a pressure-compensated hydraulic pump to deliver 45 gpm at 4000 psi while operating at 30,000 rpm with MIL-H-5606B hydraulic fluid. The new pump concepts were the product of previous Air Force programs and included a pivoting-tip vane for hydrodynamic load support and a two-lobed deformable cam ring for variable displacement. During this program both component experiments and pump evaluations were performed.
