Gas turbine engine with ceramic panel
A gas turbine engine ceramic panel assembly includes a ceramic liner that has a slot and includes a hole. An insert is received in the slot and provides a female fastening element aligned with the hole. A method of manufacturing a ceramic panel assembly includes the steps of forming a ceramic liner with a slot, installing an insert into the slot, and securing the ceramic liner to a structure using a fastening assembly.
1. A gas turbine engine ceramic panel assembly comprising:
a combustor housing;
a ceramic liner having a slot and including a hole, wherein the ceramic liner is provided by laminated ceramic matrix composite (CMC) layers, the laminated CMC layers arranged about the slot;
an insert is received in the slot and wherein a threaded bushing is secured to the insert to provide a female fastener in the slot aligned with the hole;
an anti-rotation feature is provided between and prevents relative rotation between the threaded bushing and the insert; and
a male fastener securing the ceramic liner to the combustor housing.
2. The gas turbine engine ceramic panel assembly according to claim 1 , wherein the insert is a metallic material.
3. The gas turbine engine ceramic panel assembly according to claim 1 , wherein the insert is slidably received within the slot.
4. The gas turbine engine ceramic panel assembly according to claim 1 , wherein the slot forms a rib in the ceramic liner.
5. The gas turbine engine ceramic panel assembly according to claim 1 , wherein the ceramic liner circumscribing the male fastener.
6. The gas turbine engine ceramic panel assembly according to claim 1 , wherein the insert is constructed from a ceramic material.
7. A gas turbine engine ceramic panel assembly comprising:
a combustor housing;
a ceramic liner having a slot and including a hole, wherein the ceramic liner is provided by laminated CMC layers, the laminated CMC layers arranged about the slot;
an insert is received in the slot and wherein threaded bushing is secured to and slidingly received within the insert to provide a female fastener in the slot aligned with the hole, the threaded bushing being structurally distinct from the insert; and
a male fastener securing the ceramic liner to the combustor housing.
8. The gas turbine engine ceramic panel assembly according to claim 7 , wherein the insert is a metallic material.
9. The gas turbine engine ceramic panel assembly according to claim 7 , wherein the insert is slidably received within the slot.
10. The gas turbine engine ceramic panel assembly according to claim 7 , wherein the slot forms a rib in the ceramic liner.
11. The gas turbine engine ceramic panel assembly according to claim 7 , wherein the ceramic liner circumscribing the male fastener.
