Patent number: 10792771Abstract: Disclosed is a method of making an integrally bladed rotor. According to the method, a rotor disk comprising a radially outer rim surface is provided. A portion of the disk outer rim surface is removed, leaving a protrusion on the rotor disk outer rim surface. The disk with material removed is subjected to thermal processing. A blade comprising an airfoil and a base is positioned such that a base surface is in contact with the protrusion, and heat, pressure, and motion are applied between the blade and the disk to friction weld the base surface to the protrusion.Type: GrantFiled: September 12, 2017Date of Patent: October 6, 2020Assignee: RAYTHEON TECHNOLOGIES CORPORATIONInventors: Michael F.

Publication number: 20200122233Abstract: A powder metallurgy method includes a canister that has canister walls that define a hermetic chamber that circumscribes an open central region. A metallic alloy powder is inserted into the hermetic chamber, followed by evacuating the hermetic chamber. The canister with the metallic alloy powder is then subjected to a hot isostatic pressing process that includes heating the canister and the metallic alloy powder and applying isostatic pressure to the canister. The heating and the isostatic pressure causes fusion and consolidation of the metallic alloy powder to form a solid workpiece.Type: ApplicationFiled: October 2, 2019Publication date: April 23, 2020Inventors: Daniel A. Bales, Andrew L. Haynes

Publication number: 20200122234Abstract: A powder metallurgy method for producing a non-molybdenum-segregated article is disclosed. The method includes use of a Ni—Mo—Cr powder that has a composition in which Ni is the base element and the Mo and Cr are alloy elements. The composition comprises, by weight, at least 20% of the Mo, and the Mo is dispersed in the Ni—Mo—Cr powder. The Ni—Mo—Cr powder is inserted into a hermetic chamber of a canister, followed by evacuating the hermetic chamber. The canister with the Ni—Mo—Cr powder in the hermetic chamber is then subjected to a hot isostatic pressing process that includes heating the canister and the Ni—Mo—Cr powder and applying isostatic pressure to the canister. The heating and the isostatic pressure causes fusion and consolidation of the Ni—Mo—Cr powder to form a solid article. The Mo remains dispersed such that the solid article is non-molybdenum-segregated. The canister is then removed from the solid article.Type: ApplicationFiled: October 2, 2019Publication date: April 23, 2020Inventors: Daniel A. Bales, Ted A. Asare, Andrew L. Haynes

Patent number: 9694440Abstract: An example method of attaching an airfoil for an integrally bladed rotor includes placing a support collar in an installed position around at least a leading edge and trailing edge of an airfoil stub to be repaired in an integrally bladed rotor. The support collar and the airfoil stub together have a midline that is positioned between opposing, laterally outer surfaces of the airfoil stub when the support collar is in the installed position. The method performs linear friction welding to add a replacement airfoil to the airfoil stub.Type: GrantFiled: October 22, 2010Date of Patent: July 4, 2017Assignee: United Technologies CorporationInventors: James J.

Patent number: 9587857Abstract: Polymeric sheets suitable for use as solar concentrators in solar thermal devices are provided. Also provided are solar thermal devices incorporating the polymeric sheets. The polymeric sheets have two oppositely facing surfaces. A first pattern is defined in the first surface and a second pattern is defined in the second surface. The first pattern is designed to reduce the reflectance of light incident upon the first surface relative to the first surface in the absence of the first pattern and to channel incident light through the sheet onto the second surface. It does so by redirecting photons incident upon the first surface over a broad range of incident angles into transmittance angles that are more closely aligned with the surface normal of the polymeric sheet. The second pattern is designed to focus the photons transmitted to the second surface of the sheet onto a focal surface, such as a receptacle containing a heat-transfer medium.Type: GrantFiled: April 24, 2012Date of Patent: March 7, 2017Assignees: Morningside Technology Ventures Ltd, ZinniaTek LimitedInventors: David J. Bates, Andrew L. Haynes, Ashton C. Partridge

Patent number: 8616852Abstract: A method of repairing a rotor blade, for example on an integrally bladed rotor, includes preparing a surface on a damaged area of the blade. The blade has first and second airfoil surfaces adjoining the prepared surface that are spaced apart a distance. An edge of a patch abuts the prepared surface to provide a weld interface defining a welding plane. First and second cover sheets respectively overlap the first and second airfoil surfaces. The first and second cover sheets adjoin the edge and the first and second airfoil surfaces. The blade, patch and first and second cover sheets are welded along the welding plane providing a welded joint at the weld interface. The first and second cover sheets are substantially unsecured to the first and second airfoil surfaces subsequent to the welding operation.Type: GrantFiled: November 25, 2009Date of Patent: December 31, 2013Assignee: United Technologies CorporationInventors: Wangen Lin, Robert W.

Patent number: 8613138Abstract: A method is provided for repairing a damaged rotor blade on an integrally bladed rotor by removing a damaged portion of a damaged blade leaving a blade stub extending outwardly from the disk and performing a linear friction welding operation to attach a replacement blade segment to the blade stub. The rotor may be disposed operation using a linear friction welding apparatus. The method includes disposing a support collar about the blade stub and securing the support collar to the linear friction welding apparatus prior to a commencement of the bonding operation. A lower surface of the support collar is contoured to mate with a portion of an outer circumference surface of the rotor disk.Type: GrantFiled: March 19, 2010Date of Patent: December 24, 2013Assignee: United Technologies CorporationInventors: Herbert A.

Publication number: 20120279066Abstract: A method is disclosed for welding a first metal to a Ti-6246 alloy airfoil. The method consists of depositing weld metal by fusion welding and reshaping the airfoil to predetermined dimensions. A post weld heat treatment is applied to relieve residual stresses. Surface treatment such as laser shock peening introduces residual surface compressive stresses to enhance the mechanical integrity of the airfoil.Type: ApplicationFiled: May 6, 2011Publication date: November 8, 2012Applicant: UNITED TECHNOLOGIES CORPORATIONInventors: Herbert A.
