Abstract

A stator assembly, in accordance with various embodiments, is disclosed herein. The stator assembly comprises either a first bumper or a first tab. The first bumper or the first tab extends circumferentially outward from a mating portion of the vane towards a slot in a ring. The ring may be an outer diameter (OD) ring or an inner diameter (ID) ring. The mating portion of the vane may be coupled to the ring by a potting component. The potting component may prevent direct contact between the vane and the ring.

Claims (31)

1 . A stator assembly, comprising:

a vane comprising a suction side, a mating portion, and a first bumper, the first bumper disposed on the suction side and extending circumferentially away from the suction side;

a ring having a slot configured to receive the vane;

a potting component disposed between the mating portion of the vane and the slot of the ring, the potting component configured to join the vane and the ring.

2 . The stator assembly of claim 1 , wherein the first bumper extends substantially orthogonal to the suction side.

3 . The stator assembly of claim 1 , wherein the first bumper is disposed proximate a leading edge of the vane.

4 . The stator assembly of claim 3 , further comprising a second bumper disposed on the suction side of the vane.

5 . The stator assembly of claim 4 , wherein the second bumper is disposed proximate a trailing edge of the vane.

6 . The stator assembly of claim 1 , wherein the vane is a monolithic component.

7 . A stator assembly, comprising:

a vane comprising a suction side, a mating portion, and a first tab, the first tab disposed on the suction side and extending circumferentially away from the suction side;

a ring having a slot configured to receive the vane;

a potting component disposed between the mating portion of the vane and the slot of the ring, the potting component configured to join the vane and the ring.

8 . The stator assembly of claim 7 , wherein the first tab extends substantially orthogonal to the suction side.

9 . The stator assembly of claim 8 , further comprising a first circumferential recess disposed in the slot proximate the first tab, wherein the first circumferential recess is configured to receive the first tab.

10 . The stator assembly of claim 7 , wherein the first tab is disposed proximate a leading edge of the vane.

11 . The stator assembly of claim 10 , further comprising a second tab disposed on the suction side of the vane.

12 . The stator assembly of claim 11 , wherein the second tab is disposed proximate a trailing edge of the vane.

13 . The stator assembly of claim 12 , further comprising a second circumferential recess disposed in the slot proximate the second tab, wherein the second circumferential recess is configured to receive the second tab.

14 . The stator assembly of claim 7 , wherein the vane is a monolithic component.

15 . A gas-turbine engine, comprising:

a compressor section;

a stator assembly disposed aft of the compressor section, the stator assembly comprising:

a vane comprising a suction side, a mating portion, and a first tab or a first bumper, the first tab or the first bumper disposed on the suction side and extending circumferentially away from the suction side;

a ring having a slot configured to receive the vane; and

a potting component disposed between the mating portion of the vane and the slot of the ring, the potting component configured to join the vane and the ring.

16 . The gas-turbine engine of claim 15 , wherein the ring further comprises a first circumferential recess disposed in the slot proximate the first tab, wherein the first tab or the first bumper is the first tab.

17 . The gas-turbine engine of claim 16 , wherein the first tab is disposed proximate a leading edge of the vane, wherein the vane further comprises a second tab disposed on the suction side proximate a trailing edge of the vane, the second tab extending circumferentially away from the suction side.

18 . The gas-turbine engine of claim 17 , wherein the ring further comprises a second circumferential recess disposed in the slot proximate the second tab, wherein the second circumferential recess is configured to receive the second tab.

19 . The gas-turbine engine of claim 15 , wherein the first bumper or the first tab is the first bumper.

20 . The gas-turbine engine of claim 15 , wherein the vane is a monolithic component.
