Abstract:
1. A system for internal inspection of a gas turbine, comprising: a mounting flange for affixation to a gas turbine inspection port; an inspection scope having an elongated body defining a central axis, a proximal end coupled to the mounting flange, and a distal end for insertion within a gas turbine inspection port; a linear drive for translating the inspection scope along its central axis, coupled thereto; a rotational drive for rotating the inspection scope about its central axis, coupled thereto; a camera head, having a field of view, coupled to the inspection scope body distal end; a camera coupled to the inspection scope, for capturing an image transmitted by the camera head; an articulation drive, coupled to the camera head and the control system, for articulating the camera head field of view relative to the inspection scope central axis proximal and distal ends; and a control system, coupled to the linear, articulation and rotational drives and the camera, for automatically positioning the inspection scope and field of view along a pre-designated navigation path within a gas turbine to an internal area of interest and for capturing a camera image thereof without human intervention.
