More Information
Summary:A turbomachine blade clearance system includes an actuator (101) including an actuating portion (103) that can be fixed to an interior surface of a turbomachine housing (50) and a shaft (105) for actuating movement relative to the turbomachine housing, a turbomachine blade seal (107) 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 (60) of a turbomachine to maintain a predetermined gap clearance (70) between the blade seal and the blade, a waveguide (108) disposed within the shaft, and at least one antenna (106) disposed in electromagnetic communication with the waveguide such that a signal from the antenna can be directed by the waveguide.
