Abstract: An apparatus for inspecting a selected target region in an interior cavity of a turbine engine rotor includes independent sources of ultraviolet and visible light for illuminating the selected target region, an arm having a working end translatable in a principal direction so that the working end is insertable into the rotor interior cavity, a primary camera mounted at the working end of the arm for capturing an image of the selected target region, a video monitor, and means for conveying the camera image from the primary camera to the video monitor. Ideally, the arm is also translatable in a secondary direction to facilitate positioning of the camera relative to the rotor. Suitable light guides convey the ultraviolet and visible light from their respective sources to the working end of the arm. A remote camera control, which is part of the camera electronics, allows an inspector to remotely focus the camera.

Abstract: An apparatus for inspecting feedwater piping in a steam generator having “J” nozzles. A camera and light source are coupled to a yoke mounted rotatable wheel adjacent the end of an elongated flexible conduit. Control cables, for rotating the wheel, extend through the yoke and the conduit and are fastened to a second rotatable wheel. Rotation of the second wheel causes rotation of the first wheel along with the camera and light source. Control cables for the camera and light source also extend through the yoke and the flexible conduit.
