  • Publication number: 20060168809
    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.

  • Publication number: 20060083612
    Abstract: The cleaning system includes a plurality of generally dovetail-shaped slot blocks having a slot along a radial inner side, an abrasive media or belt and a backing tube. Upon insertion of the blocks into the dovetail slots of a rotor wheel and aligning the block slots with the cooling slot, the abrasive media and backing tube are inserted in the cooling slot tunnel. The abrasive media may extend through end feeder blocks. With the backing tube applying pressure radially outwardly against the abrasive media, back and forth motion applied manually from outboard of the rim of the rotor cleans the surfaces of the cooling slot without disassembly of the rotor.
