Patent number: 11673227Abstract: A method for deep roll peening a workpiece includes deep roll peening a workpiece by moving the workpiece along a feed path through multiple groups of opposed rollers that are arranged in series. Each group of opposed rollers includes a rim that defines a workpiece engagement surface that exerts a deep roll peening force on the workpiece. A deep roll peening system includes multiple groups of opposed rollers. Each of the opposed rollers is rotatably mounted and has a rim that defines a workpiece engagement surface. The workpiece engagement surfaces are spaced apart from each other by a gap. The groups are arranged in series such that the gaps define a feed path for receiving a workpiece into serial contact with the workpiece engagement surfaces.Type: GrantFiled: March 30, 2020Date of Patent: June 13, 2023Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Andrzej Ernest Kuczek, Joseph C. Rampone, Tahany Ibrahim El-Wardany, Paul R. Faughnan, Jr.

Patent number: 7967659Abstract: A method of manufacturing an integral bladed rotor is disclosed. The method includes calculating a cutting path in an area of a blank between adjacent blade locations to approximate contours of adjacent blades. A cutter is plunged into the area at an initial angle and depth that extends from an outer perimeter to the blank to an inner perimeter of the blank, in one example. The blade roots extend from the inner perimeter, and the blade tips terminate near the outer perimeter. The cutter is plunged into the area at an original angle that, in one example, is different than the initial angle. The cutter is rotated about an axis in a spiral-like fashion as the cutter extends further into the blank, along the cutting path.Type: GrantFiled: May 15, 2008Date of Patent: June 28, 2011Assignee: United Technologies CorporationInventors: Robert E. Erickson, Paul R. Faughnan, Jr.

Publication number: 20090094831Abstract: An integrally bladed rotor includes a central hub and a plurality of airfoils or blades. The blades are repaired by rebuilding their surfaces beyond the original shape, such as by adding weld material.
