  • Piloted nut
    Patent number: 10267152
    Abstract: The present application relates generally to a piloted nut. The piloted nut may be used on a tie-shaft to apply an axial load to a rotor. A piloting feature on an exterior surface of the nut provides radial piloting to the rotor. The piloted nut may be used in a gas turbine engine to apply an axial load to a rotor.
    Type: Grant

  • Angled on-board injector
    Patent number: 8562285
    Abstract: A secondary flow system provides a compact injector cooling structure for turbine blades which includes an Angled On-board Injector (AOBI) that locates a metering throat at an inward angle relative to an engine centerline. The AOBI positions the metering throat at the inward angle relative to an engine centerline to communicate cooling airflow to an angled annular section of a turbine rotor disk coverplate.

  • Process to cast seal slots in turbine vane shrouds
    Patent number: 8276649
    Abstract: A process for casting a turbine engine component is provided. The process comprises the steps of placing a refractory metal core assembly comprising two intersecting plates in a die, encapsulating the refractory metal core assembly in a wax pattern having the form of the turbine engine component, forming a ceramic shell mold about the wax pattern, removing the wax pattern, and pouring molten material into the ceramic shell mold to form the turbine engine component.
