Abstract: An inspection head for an air gap inspection device. The inspection head may include a pair of expandable shoes, an inspection device attached to the pair of shoes, and a transducer assembly attached to one of the pair of shoes.

Abstract: An inspection assembly adapted to traverse an inspection surface, the assembly includes: a crawler body including a first side and a bottom side, wherein the first side is adapted to face a first inspection surface and the bottom side is adapted to engage a second inspection surface separated from the first inspection surface by a gap; a suction module in the crawler body adapted to create a suction between the first inspection surface to bias the crawler body against the first inspection surface; at least one roller mounted in the crawler body adapted to engage the first inspection surface, and at least one mast having a mount to receive a sensor, wherein said mast extendable from the crawler body into the gap.

Abstract: The apparatus includes a track mounted in the inlet of a compressor. A manipulator is mounted for movement about the track and carries three modules, the last of which mounts a tool head for movement in a Cartesian coordinate system and about the track. A measuring head measures the location of the airfoil surface. An abrading tool mounted on the third module removes surface material from the airfoil. Subsequently, a shot-peening device, either a flapper with embedded shot or free shot is impacted against the abraded surface to strengthen the surface. Final inspection is performed by a light and camera head mounted on the third module.

Abstract: A borescope is received within a housing. The borescope includes a flexible end portion carrying the video head and a housing includes a flexible end portion comprised of ball-socket segments and a tip for following the movement of the flexible end portion of the borescope. Cooling air is provided in an annular passage between the borescope and housing for flow about the borescope to maintain the video head temperature below its temperature limitation. Two cables maintain the ball-socket segments and tip in contact with a transition piece and with one another to enable the flexible borescope end portion to follow the movement of the directionally controlled video head.

Abstract: The wedge removal apparatus includes an elongated frame having telescopic elements at opposite ends with cylinders to engage pads along opposite sides of the frame against diametrically opposed wedges of stator core slots. The frame mounts a linear drive assembly carrying a carriage for longitudinal movement relative to the drive assembly and frame. The carriage mounts diametrically opposed heads and a cylinder displaces the heads radially outwardly to engage the wedges and compress underlying ripple springs. Saws carried by the heads cut through the wedges as the carriage is displaced along the frame and without binding because of the force applied to the wedges compressing the ripple springs. The linear drive assembly is rotated to discrete circumferential positions to cut the wedges of additional diametrically opposed slots.
