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 (20)

1. A stator assembly, comprising:

a vane;

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; and

a potting embedded component disposed within the potting component, the potting embedded component configured to reduce internal tension in the potting component, wherein:

the potting embedded component comprises a sheet configured in a serpentine shape,

the potting embedded component is disposed around a perimeter of the vane, and

the potting embedded component contacts a portion of the vane and a portion of a wall of the slot.

2. The stator assembly of claim 1 , wherein the potting embedded component is non-metallic.

3. 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; and

a potting embedded component disposed within the potting component, the potting embedded component comprising a non-metallic material, wherein:

the potting embedded component is configured in a serpentine shape, and

the potting embedded component contacts a portion of the vane and a portion of a wall of the slot.

4. The gas-turbine engine of claim 3 , wherein the potting embedded component comprises a sheet disposed around a perimeter of the vane in the slot.
