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.

First claim

What is claimed is:

1. A stator assembly, comprising:
a vane;
a ring having a slot configured to receive the vane, the ring defining a gas-path surface and a non-gas-path surface spaced apart radially from the gas-path surface;
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 component is at least one of a thermoplastic elastomer, silicone, silicone rubber, and a natural rubber,
the potting embedded component is at least one of a woven structure or a chain-link structure,
a first end of the potting embedded component is tangent to the non-gas path surface of the ring,
the first end is one of a radially inner end or a radially outer end, and
a second end of the potting embedded component is tangent to a pressure side of the vane.

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

3. The stator assembly of claim 1 , wherein the potting embedded component is disposed only on a pressure side of the vane.

4. 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 the ID 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 component is at least one of a thermoplastic elastomer, silicone, silicone rubber, and a natural rubber,
the potting embedded component is at least one of a woven structure or a chain-link structure,
the vane extends radially through the slot and includes an end spaced apart radially inward a radial distance from a non-gas path surface of the ID ring,
the non-gas path surface is spaced apart radially inward from a gas-path surface of the ID ring,
the potting embedded component is disposed only within the radial distance when measured radially from the non-gas path surface toward the end of the vane, and
the potting embedded component is disposed only on a pressure side of the vane.

5. 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 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 component is at least one of a thermoplastic elastomer, silicone, silicone rubber, and a natural rubber,
the potting embedded component is at least one of a woven structure or a chain-link structure,
the vane extends radially outward a radial distance from a non-gas path surface of the OD ring,
the non-gas path surface is spaced apart radially outward from a gas-path surface of the OD ring,
the potting embedded component is disposed within the radial distance when measured radially from the non-gas path surface toward the end of the vane, and
the potting embedded component is disposed only on a pressure side of the vane.
