Abstract
A stator vane assembly is provided. The stator vane assembly may comprise a stator vane, an outer shroud, and a spring. A first end of the stator vane may be fixed to an inner diameter (ID) surface of a vane platform. A slot may be disposed in a surface of the outer shroud, wherein a portion of the stator vane is configured to be located within the slot. In various embodiments, the stator vane may be configured to translate in a radial direction in response to a force between the stator vane and a rotor. In various embodiments, the spring may be configured to be coupled to an outer diameter (OD) surface of the vane platform, wherein the spring is configured to bias the ID surface of the vane platform toward the outer shroud.
Claims19
A stator vane assembly, comprising:
- a stator vane, wherein a first end of the stator vane is fixed to an inner diameter (ID) surface of a vane platform;
- an outer shroud, wherein the outer shroud comprises a slot extending radially through the outer shroud, wherein a portion of the stator vane is configured to be located within the slot, wherein the stator vane is configured to translate relative to the outer shroud in a radial direction in response to a force between the stator vane and a rotor;
- and
- a spring, wherein the spring is configured to be coupled to an outer diameter (OD) surface of the vane platform, wherein the spring is configured to bias the ID surface of the vane platform toward the outer shroud
- wherein the outer shroud is configured to be coupled to a case located radially outward from the outer shroud.
A compressor section, comprising:
- a stator vane, wherein a first end of the stator vane is fixed to an inner diameter (ID) surface of a vane platform;
- an outer shroud, wherein the outer shroud comprises a slot extending radially through the outer shroud, wherein a portion of the stator vane is configured to be located within the slot, wherein the stator vane is configured to translate relative to the outer shroud in a radial direction in response to a force between the stator vane and a rotor;
- a case, wherein the outer shroud is located radially inward of the case, wherein the outer shroud is coupled to the case;
- and
- a spring, wherein the spring is coupled between an outer diameter (OD) surface of the vane platform and an inner diameter surface of the case, wherein the spring is configured to bias the ID surface of the vane platform toward the outer shroud.
A gas turbine engine, comprising:
- a compressor section, comprising:
- a stator vane, wherein a first end of the stator vane is fixed to an inner diameter (ID) surface of a vane platform;
- a rotor, wherein the rotor is located radially inward of the stator vane assembly;
- an outer shroud, wherein the outer shroud comprises a slot extending radially through the outer shroud, wherein a portion of the stator vane is configured to be located within the slot, wherein the stator vane is configured to translate relative to the outer shroud in a radial direction in response to a force between the stator vane and the rotor;
- a case, wherein the outer shroud is located radially inward of the case, wherein the outer shroud is coupled to the case;
- and
- a spring, wherein the spring is coupled between an outer diameter (OD) surface of the vane platform and an inner diameter surface of the case, wherein the spring is configured to bias the ID surface of the vane platform toward the outer shroud, wherein the spring is configured to at least one of compress and decompress in response to the translating.
