Abstract
A variable outer air seal support system according to an exemplary aspect of the present disclosure includes, among other things, a case having a plurality of slots, and an extension of a variable outer air seal segment. The extension provides at least one extension aperture. A connector pin is configured to move within the slot to move the variable outer air seal segment from a first position to a second position. The variable outer air seal segment overlaps a circumferentially adjacent variable outer air seal segment more in the first position than in the second position.

A variable outer air seal support system, comprising:
- a case having plurality of slots;
- an extension of a variable outer air seal segment, the extension providing at least one extension aperture;
- and
- a connector pin extending through both one of the plurality of slots and the at least one extension aperture, the connector pin configured to move within the slot to move the variable outer air seal segment from a first position to a second position, the variable outer air seal segment overlapping a circumferentially adjacent variable outer air seal segment more in the first position than in the second position.
A variable outer air seal connector pin, comprising:
- a connector pin having a first portion and a second portion, the linkage configured to couple a segment of a blade outer air seal to an actuator arm,
- a first portion having a bore that is threaded and extends from a leading surface along an axis;
- and
- a second portion having an extension that is threaded, wherein the bore longer than the extension such that the leading surface contacts the second portion when the first portion is secured relative to the second portion.
A method of actuating a variable outer air seal system, comprising:
- moving a connector pin within a slot to move a variable outer air seal segment from a first position to a second position, the variable outer air seal segment overlapping a circumferentially adjacent variable outer air seal segment more in the first position than in the second position.
