Swirler mount interface for gas turbine engine combustor
A swirler for a combustor of a gas turbine engine includes a swirler outer body with a male snap component and/or female snap component of a snap-fit interface defined around a swirler central longitudinal axis. A bulkhead assembly for a combustor of a gas turbine engine includes a swirler mounted to a bulkhead support shell through a snap-fit interface.
1. A forward assembly for a combustor of a gas turbine engine, the forward assembly comprising:
a bulkhead support shell;
a swirler mounted to said bulkhead support shell through a snap-fit interface; and
a cowl mounted to said bulkhead support shell,
wherein said cowl includes a circumferentially distributed hood port to extend into contact with said swirler to apply an axial load to said swirler, and said snap-fit interface is located along a frustro-conical surface of said swirler.
2. The forward assembly as recited in claim 1 , wherein said swirler includes a male snap component.
3. The forward assembly as recited in claim 2 , wherein said bulkhead support shell includes a female snap component around a swirler central longitudinal axis.
4. The forward assembly as recited in claim 3 , wherein said male snap component extends radially outward with respect to the swirler central longitudinal axis.
5. The forward assembly as recited in claim 1 , wherein said snap-fit interface is located along a swirler outer body.
6. The forward assembly as recited in claim 5 , further comprising a swirler inner body mounted within said swirler outer body along a swirler central longitudinal axis.
7. The forward assembly as recited in claim 6 , further comprising a guide housing mounted to said swirler inner body.
8. The forward assembly as recited in claim 7 , further comprising a capture plate mounted to said guide housing to retain a nozzle guide such that said nozzle guide is movable with respect to said guide housing.
9. The forward assembly as recited in claim 1 , wherein said frustro-conical surface of said swirler is defined along a swirler outer body.
10. The forward assembly as recited in claim 9 , further comprising a guide housing mounted to a swirler inner body mounted at least partially within said swirler outer body, and a capture plate mounted to said guide housing to retain a nozzle guide such that said nozzle guide is movable with respect to said guide housing.
11. A method of assembling a swirler into a bulkhead support shell of a gas turbine engine, the method comprising:
snap fitting at a snap-fit interface the swirler into the bulkhead support shell along a swirler axis; and
mounting a cowl to said bulkhead support shell,
wherein said cowl includes a circumferentially distributed hood port that extends into contact with the swirler to apply an axial load to the swirler, and the snap-fit interface is located along a frustro-conical surface of the swirler.
12. A forward assembly for a combustor of a gas turbine engine, the forward assembly comprising:
a bulkhead support shell;
a swirler mounted to said bulkhead support shell through a snap-fit interface located along a frustro-conical surface of said swirler.
