Abstract
A gas turbine engine component (50, 100, 150, 160, 174, 206, 236), including: a surface (54) subject to loss caused by a wear instrument during operation of the component in a gas turbine engine and a performance feature (80, 82, 102, 152, 162, 172, 200, 230) associated with the surface. The surface and the performance feature interact in a manner that changes with the loss such that a change in performance of the gas turbine engine resulting from the loss is mitigated.
Claims4
A gas turbine engine component, comprising:
- a surface subject to loss caused by a wear instrument during operation of the component in a gas turbine engine;
- and
- a performance featured associated with surface;
- wherein the surface and the performance feature interact in a manner that changes with the loss such that a change in performance of the gas turbine engine resulting from the loss is mitigated,
- wherein before any loss the performance feature is disposed entirely below the surface subject to the loss,
- wherein the performance feature comprises a flowable material that is released upon exposure and which flows onto the surface upon the exposure, wherein the gas turbine engine component comprises a seal element, wherein the wear instrument comprises a sealing surface of an adjacent component, wherein the interaction comprises physical contact between the seal element and the sealing surface, and wherein the flowable material comprises a sealant.

A gas turbine engine component, comprising:
- a component material subject to loss during operation caused by a wear instrument, the component material comprising a substrate surface subject to the loss;
- a performance feature disposed entirely below the substrate surface subject to the loss to become exposed upon the loss,
- wherein the gas turbine engine component and the wear instrument together perform a function;
- wherein, before the loss, the function occurs via the substrate surface and at the substrate surface,
- wherein, after the loss, the function occurs via the performance feature and at a location above the substrate surface,
- wherein the performance feature comprises a sacrificial casing that sacrifices upon exposure, thereby releasing a flowable material onto the substrate surface.
