| 20150068262 | APPARATUS AND METHOD FOR SHOT PEENING OF BLADE MOUNTING AREAS ON A ROTOR ARRANGEMENT DISC - An apparatus for shot peening blade mounting areas on a disc of a rotor includes a peening nozzle unit which streams shot peening media along a longitudinal axis. The unit includes a nozzle outlet which extends at least partially in a circumferential direction of the unit, and a deflection arrangement with a deflection area for the media. The deflection area is at least partially cone or half-hyperboloid shaped, such that the media passes the nozzle outlet over an angle range in circumferential direction after being deflected by the deflection arrangement. A method for shot peening the blade mounting areas positions the unit in a slot profile of a blade mounting area and guides the unit along the contour of the slot profile with the nozzle outlet facing the contour of the slot profile to approximately uniformly peen the contour of the slot profile. | 03-12-2015 |
