Patent ID: 7950297

Claim:
A nondestructive inspection head system for the inspection of a turbine disk component on a turbine rotor assembly, comprising: means for raising and lowering an interchangeable inspection head along a Y-axis into a location to be inspected; the interchangeable inspection head configured to inspect a turbine disk component comprising; a Y-axis drive; a drive selected from the group consisting of an X-axis drive, a Θ-axis drive and a Φ-axis drive; a Z-axis drive, wherein the Z-axis drive includes a motor structured to drive the head in a first direction, and a spring structured to drive the head in an opposing direction, wherein a plurality of interconnected, substantially parallel slides adjacent to each other and structured to slide with respect to each other; an arm structured to actuate sliding motion of the slides; a spring structured to bias the arm in a first direction; and a motor-driven pulley structured to move the arm in the opposing direction; a sensor; and a coupling medium delivery/recirculation system structured to: dispense a coupling media between the sensor and the turbine disk, and recirculate the coupling media via a catch basin arranged below the turbine disk.
