Abstract

A bracket assembly for a gas turbine engine includes a bracket base with a separation between a first bended feature and a second bended feature. A doubler is mechanically fastened adjacent to the separation. Another bracket assembly for a gas turbine engine includes a bracket base with a separation between a first bended feature and a second bended feature. A cushioned tube support is welded to the bracket base. A doubler is mechanically fastened adjacent to the separation. A method of assembling a bracket assembly for a gas turbine engine includes mechanically fastening a doubler to a bracket base adjacent to a separation between a first bended feature and a second bended feature.

Claims

1. An assembly for a gas turbine engine, comprising:

a bracket base with a separation between a first bended feature and a second bended feature;

a doubler fastened adjacent to the separation;

a cushioned tube support welded to the bracket base; and

a buffer tube supported by the cushioned tube support,

wherein the doubler is “

L”

shaped, and

wherein the doubler is fastened to the bracket base and the cushioned tube support.

2. The assembly as recited in claim 1, wherein the doubler bridges the separation.

3. The assembly as recited in claim 1, wherein the doubler includes a doubler separation adjacent to the separation.

4. The assembly as recited in claim 1, wherein the first bended feature and the second bended feature are directed in generally opposite directions on either side of the separation.

5. The assembly as recited in claim 4, wherein the first bended feature and the second bended feature each include at least one fastener aperture.

11. The assembly as recited in claim 1, further comprising:

a second cushioned tube support welded to the bracket base; and

a second buffer tube supported by the second cushioned tube support.

12. The assembly as recited in claim 1, wherein the doubler is mechanically fastened adjacent to the separation, and wherein the doubler is mechanically fastened to the bracket base and the cushioned tube support.

6. An assembly for a gas turbine engine, comprising:

a bracket base with a separation between a first bended feature and a second bended feature, the bracket base including a crack in proximity to the separation;

a cushioned tube support welded to the bracket base; and

a doubler fastened adjacent to the separation,

wherein the doubler is “

L”

shaped,

wherein the doubler is fastened to the bracket base and the cushioned tube support, and

wherein the crack is a result of a stress riser formed in the bracket base due to the separation.

7. The assembly as recited in claim 6, wherein the doubler is riveted to the bracket base.

8. The assembly as recited in claim 6, wherein the doubler is riveted to the bracket base and the cushioned tube support.

9. The assembly as recited in claim 6, wherein the first bended feature and the second bended feature are directed in generally opposite directions.

10. The assembly as recited in claim 9, wherein the first bended feature and the second bended feature each include at least one fastener aperture.
