Abstract

The present disclosure provides a wear liner for a stator vane that has a first hook and a second hook that are connected by a base, providing in a generally S-shaped channel. The wear liner includes an outer surface that is adapted to lie against a first component and an inner surface that is adapted to lie against a second component. The first hook of the wear liner includes a first engaging end that is adapted to engage a first component, while the second hook is adapted to engage the second component. The first component may comprise a vane foot and the second component may comprise a slot for receiving and securing the vane foot.

First claim

What is claimed is:

1. An assembly comprising:
a vane foot comprising a forward end, an aft end, and a recess on at least one of the forward end and the aft end; and
a wear liner for the vane foot, the wear liner comprises a sheet of material comprising a first hook and a second hook connected by a base;
wherein the first hook comprises a first engaging end and the second hook comprises a second engaging end;
the first engaging end defines a first terminus of the sheet of material and the second engaging end defines a second terminus of the sheet of material, and the first terminus is opposite the second terminus;
the sheet of material comprises an outer surface adapted to lie against the vane foot, the first engaging end of the first hook configured to press against, and seal to the vane foot;
the first hook is configured to receive the vane foot;
the first engaging end comprises a first curve and extends into the recess, and the first engaging end terminates at the recess.

2. The assembly of claim 1 , wherein the sheet of material comprises a single sheet.

3. The wear liner of claim 1 , wherein the first hook is disposed about the vane foot.

4. The assembly of claim 1 , wherein the wear liner further comprises an inner surface adapted to lie against a second component, the second engaging end of the second hook is configured to press against and seal to the second component.

5. The assembly of claim 4 , wherein the second component is a case including a slot.

6. The assembly of claim 5 , wherein the second engaging end comprises a second curve intersecting the slot.

7. The assembly of claim 1 , wherein the first engaging end extends in a first direction and the second engaging end extends in a second direction perpendicular to the first direction.

8. A method of installing a wear liner within a gas turbine engine comprising:
inserting the wear liner into an inner diameter of a fan case, the wear liner comprising a sheet of material comprising a first hook and a second hook connected by a base;
wherein the first hook comprises a first engaging end and the second hook comprises a second engaging end;
the first engaging end defines a first terminus of the sheet of material and the second engaging end defines a second terminus of the sheet of material, and the first terminus is opposite from the second terminus;
the wear liner having an outer surface pressed against a vane foot, the first engaging end of the first hook engaging the vane foot;
the first engaging end terminates at the vane foot;
the vane foot is received by the first hook;
the vane foot comprises a forward end, an aft end, and a recess on at least one of the forward end and the aft end;
the first engaging end comprises a first curve and extends into the recess, and the first engaging end terminates at the recess.

9. The method of claim 8 , wherein the sheet of material is formed from a single sheet.

10. The method of claim 8 , wherein the wear liner further comprises an inner surface pressed against a second component, wherein the second engaging end of the second hook is engaging the second component.

11. The method of claim 10 , wherein the second component is a case including a slot.

12. The method of claim 11 , wherein the second engaging end is formed to include a second curve intersecting the slot.

13. The method of claim 8 , wherein the first engaging end extends in a first direction and the second engaging end extends in a second direction perpendicular to the first direction.
