Combustor shell attachment
A combustor shell is provided. The combustor shell may include a first aperture at least partially defined by an inner wall of the combustor shell and passing from a diffuser-facing side of the combustor shell to a combustor-facing side of the combustor shell. The combustor shell may include a spacer comprising a first segment coupled to a first flange, wherein the first flange is disposed on the diffuser-facing side of the combustor shell, wherein an outer wall of the spacer is coupled with at least a portion of an inner wall of the combustor shell.
1. A combustor shell comprising:
a first aperture at least partially defined by an inner wall of the combustor shell and passing from a diffuser-facing side of the combustor shell to a combustor-facing side of the combustor shell; and
a spacer comprising a first segment coupled to a first flange, wherein the first flange is disposed on the diffuser-facing side of the combustor shell, wherein an outer wall of the spacer is coupled with at least a portion of the inner wall of the combustor shell, wherein the spacer comprises threads on a spacer inner wall of the spacer.
2. The combustor shell of claim 1 , wherein the first aperture of the combustor shell is an oblong shape.
3. The combustor shell of claim 1 , wherein the spacer is configured to engage an attachment feature of a combustor panel.
4. The combustor shell of claim 3 , wherein a contact length between the spacer and the attachment feature is greater than a distance between the diffuser-facing side of the combustor shell and the combustor-facing side of the combustor shell.
5. The combustor shell of claim 1 , wherein the spacer further comprises a second flange coupled with the first segment and disposed on the combustor-facing side of the combustor shell.
6. The combustor shell of claim 1 , wherein the spacer further comprises a spacer aperture at least partially defined by the spacer inner wall of the spacer.
7. A gas turbine engine comprising,
a combustor, the combustor comprising the combustor shell in accordance with claim 1 .
8. A method of mounting a combustor panel to a combustor shell, comprising:
inserting a spacer into the combustor shell, the spacer comprising a spacer aperture at least partially defined by an inner wall of the spacer, wherein the spacer comprises threads on the inner wall of the spacer;
engaging an attachment feature of the combustor panel through the spacer aperture; and
engaging a nut on the attachment feature.
9. The method of claim 8 , further comprising machining a first aperture into the combustor shell.
10. The method of claim 8 , further comprising torquing the nut.
11. A combustor shell comprising:
a first aperture at least partially defined by an inner wall of the combustor shell and passing from a diffuser-facing side of the combustor shell to a combustor-facing side of the combustor shell; and
a spacer comprising a first segment coupled to a first flange, wherein the first flange is disposed on the diffuser-facing side of the combustor shell, wherein an outer wall of the spacer is coupled with at least a portion of the inner wall of the combustor shell, wherein the spacer further comprises a second flange coupled with the first segment and disposed on the combustor-facing side of the combustor shell.
12. A gas turbine engine comprising, a combustor, the combustor comprising the combustor shell in accordance with claim 11 .
