Abstract
An endwall assembly for an airfoil of a gas turbine engine includes a first fiber layer, a second fiber layer forming a gas path surface, and a contoured insert disposed between the first and second fiber layers, wherein the second fiber layer conforms to a contoured surface of the contoured insert such that the contoured surface defines a geometry of the gas path surface.
Claims9
An endwall assembly for an airfoil of a gas turbine engine, the endwall assembly comprising:
- a first fiber layer;
- a second fiber layer forming a gas path surface;
- and
- a first contoured insert and a second contoured insert, the first and second contoured inserts disposed between the first and second fiber layers, wherein the second fiber layer conforms to a contoured surface of the first contoured insert and the second contoured insert such that the contoured surface defines a geometry of the gas path surface;
- wherein the contoured surface of each of the first and second contoured inserts comprises a protrusion and/or a depression;
- and
- wherein the first contoured insert is disposed adjacent to the second contoured insert and comprises a first mating edge having a geometry configured to mate with a corresponding second mating edge of the second contoured insert.
