Abstract

Claims (17)

1. A method for cooling a radial stack joint comprising:

providing a first part and a second part as a radially stacked joint, the first part including a radially inward facing surface contacting a corresponding radially outward facing surface of the second part over an extent, and one of the contacting radially inward facing surface and the radially outward facing surface being a tongue extending from an associated one of the first and second parts, with a fastener extending through the radially inward facing surface of the first part and the radially outward facing surface of the second part in the extent and configured to maintain the relative positions of the first and second part; and

providing cooling air from at least a first cooling air source to a channel within the radial stack joint, the channel being defined on at least one mating surface of the radial stack joint;

providing the channel between the tongue and another of the first and second parts; and

wherein the channel is formed into the tongue.

2. The method of claim 1 , wherein a non-mating surface of at least one of the first and second parts is cooled via a plurality of cooling holes connected to the channel.

3. The method of claim 1 , wherein the channel vents the cooling air through an interface gap of the radial stack joint.

4. The method of claim 1 , wherein the channel includes at least one corner.

5. The method of claim 1 , wherein the first and second parts are panels in a gas turbine engine combustor.

6. The method of claim 1 , wherein the tongue protruding from an edge of the associated one of the first and second parts, with the edge extending for a first distance that is greater than a second distance through which the tongue extends.

7. The method of claim 6 , wherein the channel is between the fastener and the edge.

8. A method for cooling a radial stack joint comprising:

providing a first part and a second part as a radially stacked joint, the first part including a radially inward facing surface contacting a corresponding radially outward facing surface of the second part over an extent, and one of the contacting radially inward facing surface and the radially outward facing surface being a tongue extending from an associated one of the first and second parts, with a fastener extending through the radially inward facing surface of the first part and the radially outward facing surface of the second part in the extent and configured to maintain the relative positions of the first and second part;

providing cooling air from at least a first cooling air source to a channel within the radial stack joint, the channel being defined on at least one mating surface of the radial stack joint;

wherein the tongue protruding from an edge of the associated one of the first and second parts, with the edge extending for a first distance that is greater than a second distance through which the tongue extends; and

wherein the channel is formed into the tongue.

9. The method of claim 8 , wherein the channel is between the fastener and the edge.
