Patent number: 11421555Abstract: A flange includes a flange body and a scallop feature. The flange body is annularly disposed about a longitudinal axis. The flange body includes a first radial side and a second radial side radially opposite the first radial side. The flange body defines a first fastener hole and a circumferentially adjacent second fastener hole. Each of the first fastener hole and the second fastener hole are formed through the flange body. The scallop feature is formed through the flange body and disposed circumferentially between the first and second fastener holes. The scallop feature extends radially from the first radial side through at least a portion of the flange body. The scallop feature includes a first side and a second side, parallel to the first side.Type: GrantFiled: December 7, 2018Date of Patent: August 23, 2022Assignee: Raytheon Technologies CorporationInventors: Michael C. Weber, Konstantinos P. Giannakopoulos, Robert B. Fuller, Bill Nguyen, Alexei T. Marqueen

Patent number: 11085322Abstract: A borescope plug system includes a housing, a driver, and a spring. The housing includes a first housing end and a second housing end. The housing further includes a longitudinally extending centerline extending between the first housing end and the second housing end. The driver is disposed at least partially within the housing along the longitudinally extending centerline and includes a first driver end and a second driver end. The spring is disposed within the housing and couples the housing to the driver. The driver is configured to move within the housing, along the longitudinally extending centerline, to engage the first driver end with a borescope plug of a borescope plug port, and to install or remove the borescope plug from the borescope plug port based on a rotation of the driver about the longitudinally extending centerline.Type: GrantFiled: October 4, 2018Date of Patent: August 10, 2021Assignee: Raytheon Technologies CorporationInventors: Joon Ha, Konstantinos P. Giannakopoulos

Patent number: 11067090Abstract: An apparatus is provided that includes a rotor bore and a bore basket. The bore basket extends axially between a first and second axial ends. The bore basket includes an engagement panel, and cylindrical inner and outer radial panels. The inner and outer radial panels extend substantially between the first and second axial ends. The inner radial panel is disposed radially inside of and separated from the outer radial panel, defining an annular passage disposed there between. The bore basket includes a plurality of inlet apertures in fluid communication with the annular passage at a first axial position, and a plurality of exit apertures in fluid communication with the annular passage at a second axial position. The second axial end of the bore basket is attached to an inner radial hub of the rotor bore, and the rotor bore and bore basket are a unitary structure.Type: GrantFiled: February 21, 2020Date of Patent: July 20, 2021Assignee: Raytheon Technologies CorporationInventor: Konstantinos P.

Patent number: 8888458Abstract: A turbine rotor balancing system comprises a circumferential array of mounting features. One or more balance weights are each mounted to the respective associated said mounting feature. Each balance weight comprises: a front wall along the forward face of the mounting feature; an aft wall along the aft face of the mounting feature; and a radially inboard wall. One or more fasteners each extend at least partially through holes of the front wall and rear wall of an associated said balance weight and through a hole of the associated said mounting feature. An abutment surface of the rotor is positioned to engage an outboard end of at least one of the front wall and aft wall of each said balance weight to resist outward radial movement of the weight.Type: GrantFiled: March 12, 2012Date of Patent: November 18, 2014Assignee: United Technologies CorporationInventors: Scott C. Billings, Zhen Wu, Konstantinos P. Giannakopoulos
