Abstract
A hollow vane assembly including an open body including an interior; a cover brazed to the open body to form at least one flow passage; and at least one surface feature on an interior surface of the cover.
Claims13
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 a cover, the cover being configured to attach to the open body to form at least one flow passage;
- forming at least one surface feature on an interior surface of the cover prior to brazing the cover to the open body, the surface feature configured to be proximate the interior;
- 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 surface feature on an interior surface of the cover prior to attaching the cover to the open body;
- and
