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 at least one ply formed in the cover.
Claims20
A process of tailoring vibratory characteristics of a cover for an open body hollow vane assembly comprising:
- forming the 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 at least one ply in the cover;
- disposing a dampener material between an outer layer and an inner layer of the cover to form the at least one ply in the cover;
- and
- brazing the cover to the open body.

A process for modifying a vibratory characteristic of a cover to an open body comprising:
- forming an 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 a cover, the cover being configured to couple with the open body proximate the pressure side to form at least one flow passage;
- forming at least one ply in the cover;
- layering a dampener material between an outer layer and an inner layer of the cover;
- and
- attaching the cover to the open body.
