Abstract
A large flow of high pressure fuel is supplied to a gas turbine engine by mounting a small modified vortex pump over or around a main high speed shaft. The pump includes a plurality of short, stubby impeller blades rotating at a very high speed within a fuel filled annular chamber having an axial fuel inlet and a tangential fuel outlet. A pump booster and priming system ensures the pump fills with fuel during operation.
