Abstract

A liner panel for a combustor of a gas turbine engine is provided that includes a first attachment and a second attachment that extends from a cold side of the liner panel. The first attachment is different than the second attachment. A combustor of a gas turbine engine is provided that includes an inner combustor wall assembly with an inner support shell and a multiple of inner liner panels. At least one of the multiple of inner liner panels includes a first inner attachment to the inner support shell and a second inner attachment to the inner support shell. The first inner attachment is different than, and upstream of, the second inner attachment. An outer combustor wall assembly is spaced from the inner combustor wall assembly to define an annular combustion cavity therebetween.

First claim

What is claimed is:

1 . A liner panel for a gas turbine engine, comprising:
a first attachment; and a second attachment that extends from a cold side of the liner panel; wherein the first attachment is different than the second attachment.

2 . The liner panel as recited in claim 1 , wherein the first attachment includes a stud and a clip engageable with the stud.

3 . The liner panel as recited in claim 2 , wherein the first attachment is upstream of the second attachment.

4 . The liner panel as recited in claim 3 , wherein the second attachment includes a threaded stud and a nut.

5 . The liner panel as recited in claim 5 , wherein the first attachment includes a stud and a clip engageable with the clip.

6 . The liner panel as recited in claim 3 , wherein the second attachment includes a trapped interface.

7 . The liner panel as recited in claim 1 , wherein the first attachment includes a trapped interface.

8 . The liner panel as recited in claim 7 , wherein the second attachment includes a stud and a clip engageable with the stud.

9 . The liner panel as recited in claim 8 , wherein the first attachment is upstream of the second attachment.

10 . The liner panel as recited in claim 1 , wherein the liner panel is manufactured of a ceramic.

11 . A combustor of a gas turbine engine, comprising:
an inner combustor wall assembly with an inner support shell and a multiple of inner liner panels, at least one of the multiple of inner liner panels including a first inner attachment to the inner support shell and a second inner attachment to the inner support shell, wherein the first inner attachment is different than, and upstream of, the second inner attachment; and an outer combustor wall assembly spaced from the inner combustor wall assembly to define an annular combustion cavity therebetween.

12 . The combustor as recited in claim 11 , wherein the first inner attachment includes a stud and a clip engageable with the stud.

13 . The combustor as recited in claim 12 , wherein the second inner attachment includes a threaded stud and a nut.

14 . The combustor as recited in claim 12 , wherein the second inner attachment includes a trapped interface.

15 . The combustor as recited in claim 11 , further comprising a bulkhead assembly mounted to the inner combustor wall assembly and the outer combustor wall assembly.

16 . The combustor as recited in claim 15 , wherein the first inner attachment includes a trapped interface with a bulkhead panel of the bulkhead assembly.

17 . The combustor as recited in claim 16 , wherein the multiple of inner liner panels are manufactured of a ceramic.

18 . The combustor as recited in claim 17 , wherein the bulkhead panel is manufactured of a metallic alloy.

19 . The combustor as recited in claim 11 , wherein the outer combustor wall assembly includes an outer support shell and a multiple of outer liner panels, at least one of the multiple of outer liner panels includes a first outer attachment to the outer support shell and a second outer attachment to the outer support shell, and the first outer attachment is equivalent to the second outer attachment.

20 . The combustor as recited in claim 11 , wherein the first outer attachment and the second outer attachment each includes a threaded stud and a nut.
