Abstract: Systems and methods of forming a ceramic matrix composite vane with profiled endwalls are provided using a multi-piece tooling. The multi-piece tooling includes core tools as well as profiled endwall tools having three dimensional contours formed in the tools that correspond to the three dimensional shape to be formed on the vane endwalls.

Abstract: A turbine assembly for use with a gas turbine engine includes a bladed wheel assembly and a vane assembly. The bladed wheel assembly is adapted to interact with gases flowing through a gas path of the gas turbine engine. The vane assembly is located upstream of the bladed wheel assembly and adapted to direct the gases at the bladed wheel assembly.

Abstract: A turbine vane assembly adapted for use with a gas turbine engine includes an airfoil and a spar. The airfoil is formed to define a cavity that extends into the airfoil. The spar is located in the cavity to define a cooling passage that extends around the spar between the spar and the airfoil. The turbine vane assembly includes cooling features to aid heat transfer of the turbine vane assembly during operation in the gas turbine engine.
