Patent number: 10208622Abstract: A gas turbine engine comprises an exhaust section member, a turbine section member, a heat shield and a spacer. The turbine section member is coupled to the exhaust section member. The heat shield is retained between the exhaust section member and the turbine section member. The spacer is positioned between the exhaust section member and the turbine section member to produce a gap for the heat shield. In one embodiment, the exhaust section member comprises a duct and the turbine section member comprises a bearing support.Type: GrantFiled: October 6, 2014Date of Patent: February 19, 2019Assignee: United Technologies CorporationInventors: Fernando K. Grant, Fabian D. Betancourt

Publication number: 20160341070Abstract: A gas turbine engine includes a containment ring to contain liberated compressor and turbine blades and blade fragments within a core assembly. The combination of a containment gap between the core case and the containment ring and a containment layer disposed in the gap helps dissipate the energy generated by loose body impacts on the core assembly. The containment layer deforms, deflects, and/or redirects the impact energy acting in a radial direction, thereby to improve containment.Type: ApplicationFiled: August 14, 2014Publication date: November 24, 2016Applicant: United Technologies CorporationInventors: Igor S. Garcia, Shu Liu, Robert Russell Mayer, Eric Baker, Stephanie Ernst, Fernando K. Grant, Andrew S. Miller, Peter Balawajder, Paul W. Palmer

Publication number: 20160341075Abstract: A gas turbine engine includes a core assembly with a core case having a containment section for containing liberated compressor and turbine blades and blade fragments. The containment section includes first and second containment layers and the containment section is configured to have a non-linear rate of energy dissipation across the first and second containment layers, thereby to improve containment of blades and blade fragments.Type: ApplicationFiled: August 15, 2014Publication date: November 24, 2016Inventors: Shu Liu, Robert Russell Mayer, Paul W. Palmer, Peter Balawajder, Igor S. Garcia, David C. Pimenta, Stephanie Ernst, Fernando K. Grant, Eric Baker, Andrew S. Miller

Patent number: 8893502Abstract: An augmentor for a gas turbine engine includes an augmentor spray bar with a spray bar outlet, and an augmentor spray bar tip. The spray bar tip includes a tip body, a tip bushing and a tip support strut. The tip body includes a first flow passage extending therethrough between a tip inlet and a tip outlet, wherein the tip inlet is connected to the spray bar outlet. The tip bushing includes a bushing bore. The tip body extends through the bushing bore defining a second flow passage between the tip body and the tip bushing. The tip support strut connects the tip body to the tip bushing across the second flow passage.Type: GrantFiled: October 14, 2011Date of Patent: November 25, 2014Assignee: United Technologies CorporationInventors: Andreas Sadil, Steven W. Burd, Bessem Jlidi, Dennis M. Moura, Christopher R. Brdar, Leong Ma, Fernando K. Grant, Jodie L. Herrmann, Kelly A. Vanston, Matthew J. Westergard, George F. Titterton, III

Patent number: 8567745Abstract: A flanged apparatus includes an apparatus body and a flanged mount, which includes a support pylon, a first mounting flange and a second mounting flange. The support pylon includes a first pylon segment, a second pylon segment and a routing notch. The first pylon segment is cantilevered from the apparatus body, and extends to the first mounting flange. The second pylon segment is cantilevered from the first pylon support, and extends from the first mounting flange to the second mounting flange. The routing notch extends vertically between the first pylon segment and the second pylon segment. The first mounting flange and the second mounting flange extend laterally from the support pylon, and the first mounting flange is separated from the second mounting flange by a longitudinal distance and a vertical distance.Type: GrantFiled: December 15, 2011Date of Patent: October 29, 2013Assignee: United Technologies CorporationInventors: Joey Wong, Constantino V.
