Abstract: PURPOSE: A tracking system is provided to secure a stability of equipment by automating a turbine nondestructive inspection/evaluation. CONSTITUTION: A tracking system transfers a supersonic inspecting device to an inspected portion by adapting a radius of curvature in a turbine shroud band(100) and driving four magnetic wheels(70) toward a circumferential direction. The tracking system has the magnetic wheels composing of an opening washer and a washer for controlling an interval. The opening washer controls a width of a contacted face in the shroud band. A spring for buffering is installed in a wheel supporting portion to smoothly correspond to the radius of curvature. A turbine blade disk, a root portion and so on are nondestructively inspected by moving the supersonic inspecting device around the shroud band(100) toward the circumferential direction with the magnetic force through the magnetic wheels.
