Patent number: 8613590Abstract: An article of manufacture has a body formed in part of a first metal alloy and in part of a second metal alloy, the second metal alloy having a thermal coefficient of expansion that is less than the thermal coefficient of expansion of the first metal alloy. A BOAS segment for a gas turbine engine is disclosed wherein the formation of cracks due to thermal mechanical fatigue in the body of the disclosed BOAS segment is minimized, if not eliminated, through a unique construction of the disclosed BOAS segment, whether original equipment manufacture or a repaired blade outer air seal. A method for manufacture of a BOAS segment and a method for modifying a BOAS segment are disclosed.Type: GrantFiled: July 27, 2010Date of Patent: December 24, 2013Assignee: United Technologies CorporationInventors: Philip R. Belanger, Susan M. Tholen

Patent number: 8299389Abstract: A method of repairing an aperture and adjacent defect wherein one or more defects proximate an aperture are removed from the base material proximate the aperture in an arc shape. An insert containing a profile that corresponds to the arc shaped section of the base material removed is welded to the base material. The weld is accomplished with a single curved path. Next, the insert is removed to create a repaired aperture and a surrounding section that has essentially the same dimensions as the aperture and surrounding section prior to the repair.Type: GrantFiled: October 11, 2010Date of Patent: October 30, 2012Assignee: United Technologies CorporationInventor: Philip R. Belanger

Patent number: 8153922Abstract: A method of repairing an aperture and adjacent defect in a part which is started by removing one or more defects adjacent an aperture in a base material. The material is removed to create a weld seam that extends past an area of high stress concentration on the aperture. An insert of material containing a profile that corresponds to the profile of the base material removed adjacent the aperture and a combination top and runoff plate that encompasses the insert of material are provided. A backing plate is inserted underneath the combination top and runoff plate and insert such that there remains an air space between the backing plate and the combination plate which prevents the combination plate from becoming fused to the backing plate during a welding process. The insert is welded to the base material, and the backing plate is removed. Excess material is removed from the insert to obtain an aperture containing a profile essentially the same as the profile of the aperture prior to initiating the repair.Type: GrantFiled: October 11, 2010Date of Patent: April 10, 2012Assignee: United Technologies CorporationInventor: Philip R.

Patent number: 8100640Abstract: A blade outer air seal for a gas turbine has an abradable coating with a substantially uniform thickness during service use. Prior to being placed in service, the abradable coating has a central portion with a greater thickness than leading and trailing portions. When placed in service, the blade outer air seal is positioned so that the central portion of the abradable coating with the greater thickness is located in a blade rub path of the turbine blades. As a result of abrasion in the blade rub path, the thickness of the central portion of the abradable coating is reduced so that it becomes substantially similar to the thickness of the leading and trailing portions.Type: GrantFiled: October 25, 2007Date of Patent: January 24, 2012Assignee: United Technologies CorporationInventors: Christopher W.
