Abstract

A turbine engine component includes: a body bounded by an end face; and a seal slot having an opening communicating with the end face, the seal slot including a receptacle defining a boundary configured to receive and position a spline seal, and an open chamber communicating with the seal slot and extending beyond the boundary.

First claim

What is claimed is:

1. A turbine engine component, comprising:
a body bounded by a first end face and a second end face spaced from the first end face; and
a first seal slot formed in the first end face and having an opening with a closed, continuous perimeter on the first end face, the opening communicating with the first end face, the first seal slot including a receptacle having a first depth and defining a boundary configured to receive and position a spline seal, and an open chamber communicating with the receptacle and extending beyond the boundary;
the second end face including a second seal slot, the second seal slot having an opening communicating with the second end face, and including a receptacle defining a boundary configured to receive and position a spline seal, wherein the first and second seal slots are interconnected by the open chamber communicating with the receptacles.

2. The component of claim 1 wherein the first depth is measured from the first end face, and the open chamber defines a second depth measured from the first end face, wherein the second depth is greater than the first depth.

3. The component of claim 1 wherein the receptacle is defined by a pair of spaced-apart walls interconnected by an end wall, the end wall defining a rib flanked by the open chamber which is an extended recess.

4. The component of claim 1 wherein the receptacle is defined by a pair of spaced-apart walls, at least one of the walls having a tab extending therefrom.

5. The component of claim 1 wherein:
the open chamber extends beyond the perimeter of the opening in at least one direction measured parallel to the plane of the first end face.

6. A sealing apparatus for a turbine engine, comprising:
a component having a body bounded by a first end face;
a spline seal having a body and one or more standoffs extending outwardly from the body;
a seal slot having an opening communicating with the first end face, the seal slot including a receptacle defining a boundary configured to receive and position the spline seal therein, wherein the receptacle is defined by a pair of spaced-apart walls interconnected by an end wall, the end wall defining a rib flanked by an extended recess; and
wherein the spline seal is received in the seal slot, and wherein the seal slot and the spline seal are configured such that an open space is defined between the seal slot and the spline seal.

7. The apparatus of claim 6 wherein the boundary of the receptacle defines a first depth measured from the first end face, and the body includes an open chamber defining a second depth measured from the first end face, wherein the second depth is greater than the first depth.

8. The apparatus of claim 6 wherein at least one of the walls of the pair of spaced-apart walls has a tab extending therefrom.

9. The apparatus of claim 6 wherein:
the body is bounded by the first end face and a second end face spaced from the first end face;
the second end face including a second seal slot, the second seal slot having an opening communicating with the second end face, and including a receptacle defining a boundary configured to receive and position a spline seal, wherein the first and second seal slots are interconnected by the extended recess which is an open chamber communicating with the receptacles.

10. The apparatus of claim 6 wherein:
the opening defines a closed perimeter on the first end face; and
an open chamber extends beyond the perimeter of the opening in at least one direction measured parallel to the plane of the first end face.

11. A turbine engine component, comprising:
a body bounded by an end face; and
first and second seal slots each having an opening communicating with the end face, the first and second seal slots intersecting each other;
wherein each opening includes at least two spaced-apart walls defining a perimeter on the end face; and
wherein at least one of the walls includes an expanded area extending beyond the perimeter, the expanded area being a curved fillet formed at an inside corner of the intersecting first and second seal slots.

12. The component of claim 11 wherein each of the first and second seal slots includes a receptacle defining a boundary configured to receive and position a spline seal, and an open chamber communicating with the seal slot and extending beyond the boundary.

13. The component of claim 12 wherein the boundary of the receptacle defines a first depth measured from the end face, and the open chamber defines a second depth measured from the end face, wherein the second depth is greater than the first depth.

14. The component of claim 11 wherein a receptacle is defined by a pair of spaced-apart inboard and outboard walls interconnected by an end wall, the end wall defining a rib flanked by an extended recess.

15. The component of claim 11 wherein:
the opening defines a closed perimeter on the end face; and
the open chamber extends beyond the perimeter of the opening in at least one direction measured parallel to the plane of the end face.
