Abstract

There is disclosed a turbo-machine assembly configured to facilitate improved blade clearance management. In a disclosed arrangement, there is provided a turbo-machine assembly comprising: a casing (2); a fan or turbine including a blade (6) and mounted rotatably within the casing; and a detector (10) for measuring the clearance between the blade and a portion of the inner surface of the casing, wherein: the detector is configured to generate an output by interacting with the blade; and the blade (6) and detector (10) are configured so that a portion of the output from the detector that can be used to generate a measure of the clearance is independent of the axial position of the blade over a predetermined range of axial positions.
