Abstract
A case mounted bumper pad including a case contact region supporting a runner pad support; the case contact region is in operative communication with the case, the runner pad support is in operative communication with a runner pad, the runner pad is in operative communication with a sync ring of a variable vane; and a gap formed in the bumper pad proximate the case.
Claims17
A case mounted bumper pad comprising:
- a case contact region supporting a runner pad support;
- the case contact region is in operative communication with the case, the runner pad support is in operative communication with a runner pad, the runner pad is in operative communication with a sync ring of a variable vane;
- and
- a gap formed in the bumper pad proximate the case;
- wherein the gap is configured to prevent the runner pad from being heated to a predetermined temperature, the predetermined temperature comprises a thermal oxidation temperature of the runner pad;
- wherein the gap comprises dimensions tailored for a predetermined quantity of cooling air flow rate to cool the bumper pad;
- wherein the dimensions comprise at least one of a gap height, a gap width, and a gap depth configured for a predetermined quantity of cooling air flow through the gap.

A gas turbine compressor section case mounted bumper pad comprising:
- a compressor variable vane in operative communication with a sync ring;
- the sync ring mounted on the bumper pad;
- the bumper pad mounted on the case;
- a runner pad between the sync ring and the bumper pad;
- the bumper pad comprising a case contact region supporting a runner pad support;
- the case contact region is in operative communication with the case, the runner pad support is in operative communication with the runner pad, the runner pad is in operative communication with the sync ring of the variable vane;
- and
- a gap formed in the bumper pad proximate the case;
- wherein the gap is configured to prevent the runner pad from being heated to a thermal oxidation temperature of the runner pad.

A process of forming a gas turbine compressor section case mounted bumper pad comprising:
- placing a compressor variable vane in operative communication with a sync ring;
- mounting the sync ring on the bumper pad;
- mounting the bumper pad on the case;
- coupling a runner pad between the sync ring and the bumper pad;
- the bumper pad comprising a case contact region supporting a runner pad support;
- coupling the case contact region in operative communication with the case;
- coupling the runner pad support in operative communication with the runner pad;
- coupling the runner pad in operative communication with the sync ring of the variable vane;
- and
- forming a gap in the bumper pad proximate the case;
- forming the bumper pad with dimensions comprising at least one of a gap height, a gap width, and a gap depth configured for a predetermined quantity of cooling air flow through the gap.
