Abstract
A vane assembly may include a vane comprised of a composite material. An outer shroud segment may be disposed at radially outer end of the vane. An inner shroud may define an aperture. A radially inner end of the vane may be disposed within the aperture.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A vane assembly, comprising:
a vane comprising a composite material; an outer shroud segment disposed at radially outer end of the vane; and an inner shroud defining an aperture, wherein a radially inner end of the vane is disposed within the aperture.
2 . The vane assembly of claim 1 , wherein the outer shroud segment comprises the same composite material as the vane.
3 . The vane assembly of claim 2 , wherein the outer shroud segment is integrally formed with the vane.
4 . The vane assembly of claim 1 , wherein the composite material includes at least one of carbon fiber, glass fiber, aramid fiber or para-aramid fiber impregnated with a resin.
5 . The vane assembly of claim 1 , wherein the vane is cantilever mounted to the inner shroud.
6 . The vane assembly of claim 5 , further comprising a flexible material disposed within the aperture and between the vane and the inner shroud.
7 . The vane assembly of claim 6 , further comprising an abradable material formed on an inner diameter surface of the inner shroud.
8 . The vane assembly of claim 1 , wherein the inner shroud comprises at least one of a composite material or a metal.
9 . A gas turbine engine, comprising:
an engine section comprising at least one of a compressor section or a fan section, the engine section comprising:
a vane comprising a composite material,
an outer shroud segment disposed at radially outer end of the vane, and
an inner shroud defining an aperture, wherein a radially inner end of the vane is disposed within the aperture.
10 . The gas turbine engine of claim 9 , wherein the outer shroud segment comprises the same composite material as the vane.
11 . The gas turbine engine of claim 10 , wherein the outer shroud segment is integrally formed with the vane.
12 . The gas turbine engine of claim 9 , wherein the composite material includes at least one of carbon fiber, glass fiber, aramid fiber or para-aramid fiber impregnated with a resin.
13 . The gas turbine engine of claim 9 , wherein the vane is cantilever mounted to the inner shroud.
14 . The gas turbine engine of claim 13 , further comprising an engine case structure disposed radially outward from the vane, wherein the vane includes a forward axial flange configured to couple within the engine case structure.
15 . The gas turbine engine of claim 14 , further comprising a flexible material disposed within the aperture and between the vane and the inner shroud.
16 . The gas turbine engine of claim 9 , further comprising an abradable material formed on an inner diameter surface of the inner shroud.
17 . A method of manufacturing a vane assembly, comprising:
forming a vane integrally with an outer shroud segment from a composite material; disposing a radially inner end of the vane in an aperture defined by an inner shroud; forming a flexible material within the aperture; and forming an abradable material over a radially inner surface of the inner shroud.
18 . The method of manufacturing a vane assembly of claim 17 , further including cantilever mounting the vane to the inner shroud.
19 . The method of manufacturing a vane assembly of claim 17 , wherein the forming the vane integrally with the outer shroud segment includes injection molding the vane and the outer shroud segment.
20 . The method of manufacturing a vane assembly of claim 19 , wherein the composite material includes at least one of carbon fiber, glass fiber, aramid fiber or para-aramid fiber impregnated with a resin.Join the waitlist — get patent alerts
