Abstract
A hollow vane assembly including an open body including an interior; at least one cover support structure formed in said open body proximate the interior; a cover brazed to the open body to form at least one flow passage; and the open body and the cover configured as two piece substantially symmetrical halves.
Claims20
A process of creating a hollow vane assembly comprising:
- forming an open body, the open body including an interior;
- forming at least one cover support structure in said open body proximate the interior;
- forming a cover, the cover being configured to attach to the open body to form at least one flow passage;
- forming the open body and the cover as symmetrical halves;
- and
- brazing the cover to the open body, wherein the hollow vane assembly is a gas turbine engine hollow vane assembly.

A process for improving the stress capability between a cover and an open body for a hollow vane assembly comprising:
- forming the open body, the open body includes a leading edge opposite a trailing edge, the open body includes a pressure side and suction side opposite the pressure side, the open body including an interior;
- forming the cover, the cover being configured to couple with the open body proximate a centerline of the hollow vane assembly to form at least one flow passage;
- configuring the open body and the cover as symmetrically divided halves;
- and
- attaching the cover to the open body, wherein the hollow vane assembly is a gas turbine engine hollow vane assembly.
