ABSTRACT:
An active blade clearance control system for a gas turbine engine. The clearance between the tip of a rotatable blade and an inner surface of a blade track is adjusted by moving the blade track relative to the tip of the blades. A split control ring is manipulated to adjust tension therein and a resulting force is transmitted to an inner member. The plurality of blade tracks are coupled to the inner member and move in response to the force transmitted from the split control ring.
