Abstract
An assembly is disclosed for adjusting the radial position of a blade track relative to a blade of a turbine stage in a gas turbine engine. The assembly comprises a static turbine casing, a blade track carrier, a blade track support assembly, an actuator, and a blade track. The blade track carrier comprises a pair of radially extending flanges each defining at least one bore in radial and axial alignment with each other forming a pair of bores. The blade track support assembly comprises a portion extending through each bore in a pair of bores, and one or more cam-shaped portions rotatable about an axis of rotation. The blade track has an arcuate flange and a support flange, the support flange being carried by the cam-shaped portion of the blade track support assembly such that rotation of the cam-shaped portion effects radial movement of the blade track.
