Advances in gas turbine engine technology have made possible small, lightweight, very high-speed engines. Plans for future units promise a continuation of this trend. Accessory technology has not made comparable advances to date. The low-speed capability of presently available accessories threatens to severely penalize the specific weight and volume of anticipated small engine packages. This paper describes the design analysis and laboratory evaluation of a vane-type fuel pump designed to operate at gas-turbine-shaft speed. Techniques required to attain these speeds without sacrificing endurance in the vane-type pump are discussed.
