摘要: In accordance with at least one aspect of this disclosure, a pump includes a housing having one or more fluid inlets and one or more fluid outlets. The housing is configured to act as a pump housing for passing a fluid from the one or more fluid inlets to the one or more fluid outlets and configured to act as a stator for a motor. The pump also includes a cylinder encased within the housing and mounted on a shaft for rotation within the housing. The cylinder is configured to act as an impeller to drive fluid from the one or more fluid inlets through the housing to the one or more fluid outlets and configured to act as a rotor for the motor.

摘要: A impeller for a centrifugal pump has an inducer section. The inducer section has first and second pluralities of blades, each having a plurality of polygonal cross-sections defined by a plurality of vertices. The pluralities of vertices are defined by tables of vertex locations. A method of making a centrifugal pump includes forming an impeller that has an inducer section, as described above, and an impeller section. The impeller is fluidly connected downstream of the inducer section and has third, fourth, and fifth pluralities of blades, each having a plurality of polygonal cross-sectional areas defined by a plurality of vertices. The pluralities of vertices are defined by tables of vertex locations.

摘要: A two stage fuel delivery system for an aircraft includes a first stage pump including an inlet connected to a source of fuel and an outlet connected to a combustor assembly, and a second stage pump including an inlet portion connected to the source of fuel and an outlet portion connected to the combustor assembly. A bypass valve is connected between the source of fuel, the inlet, and the inlet portion. The bypass valve selectively disconnects the second stage pump from the source of fuel. A metering valve is connected to the inlet and the inlet portion. The metering valve includes a metering valve inlet and a metering valve outlet. A pressure regulating valve is connected to the metering valve. A stage monitoring system is configured to detect a change in operation of the second stage and control the bypass valve.
