Abstract

An improved stator assembly for use in a gas-turbine engine is disclosed. The stator assembly may comprise a vane, an inner diameter (ID) ring, an outer diameter (OD) ring, a vane disposed between the ID ring and the OD ring, a potting component coupling the vane to at least one of the OD ring or the ID ring, and a potting embedded component disposed within the potting component. The potting embedded component may prevent disbond of the potting component during operation of the gas-turbine engine.

Claims (21)

1. A stator assembly comprising:

a vane comprising a suction side and a pressure side;

a ring having a slot configured to receive the vane;

a potting component disposed between the vane and the ring, the potting component configured to join the vane and the ring;

a first potting embedded component disposed on the suction side of the vane, the first potting embedded component disposed within the potting component; and

a second potting embedded component disposed on the pressure side of the vane, the second potting embedded component disposed within the potting component, wherein the first potting embedded component comprises a first flange and a second flange disposed radially outward from the first flange, the second flange defining a groove, and wherein the groove receives a wall defined by the slot of the ring.

2. The stator assembly of claim 1 , wherein the first potting embedded component comprises a plurality of fingers, each finger in the plurality of fingers extending from the second flange toward the vane and radially away from the second flange.

3. The stator assembly of claim 2 , wherein each finger in the plurality of fingers includes a convex surface opposite the vane.

4. The stator assembly of claim 1 , wherein the first potting embedded component and the second potting embedded component are deformable.

5. The stator assembly of claim 1 , wherein the first potting embedded component and the second potting embedded component are configured to receive the vane during assembly of the stator assembly.

6. A gas-turbine engine comprising:

a stator assembly, comprising:

an inner diameter (ID) ring;

an outer diameter (OD) ring disposed radially outward from the ID ring;

a vane disposed between the ID ring and the OD ring;

a slot disposed in at least one of the ID ring or the OD ring;

a potting component disposed in the slot, the potting component coupling the vane to the slot;

a first potting embedded component disposed within the potting component on a pressure side of the vane; and

a second potting embedded component disposed within the potting component on a suction side of the vane, wherein the first potting embedded component and the second potting embedded component each comprise a first flange and a second flange disposed radially outward from the first flange, the second flange defining a groove, and wherein the groove receives a wall defined by the slot of one of the ID ring and the OD ring.

7. The gas-turbine engine of claim 6 , wherein the first potting embedded component and the second potting embedded component each comprises a non-metallic material.

8. The gas-turbine engine of claim 6 , wherein the first potting embedded component and the second potting embedded component each comprises a plurality of fingers, each finger in the plurality of fingers extending from the second flange toward the vane and radially away from the second flange.
