TURBOMACHINE BLADE CLEARANCE CONTROL SYSTEM

摘要

A turbomachine blade clearance system includes an actuator including an actuating portion that can be fixed to an interior surface of a turbomachine housing and a shaft for actuating movement relative to the turbomachine housing, a turbomachine blade seal operatively connected to the shaft of the actuator and configured to move relative to the turbomachine housing to adjust a distance from a turbomachine blade of a turbomachine to maintain a predetermined gap clearance between the blade seal and the blade, a waveguide disposed within the shaft, and at least one antenna disposed in electromagnetic communication with the waveguide such that a signal from the antenna can be directed by the waveguide.
