  • Fitting for mid-turbine frame of gas turbine engine
    Patent number: 9988943
    Abstract: A fitting according to an exemplary aspect of the present disclosure includes, among other things, a main body portion having a first axial end and a second axial end opposite the first axial end, an inlet provided at the first axial end, and an outlet adjacent the second axial end. The outlet includes a plurality of circumferentially spaced-apart slots formed through the main body portion, and each slot has an area within a range of 0.52 and 0.59 square inches.

  • Self-anti-rotating dual lock washer
    Patent number: 9945411
    Abstract: A disclosed lock washer includes a first opening spaced apart from a second opening for receiving fasteners and preventing rotation. A first set of tabs is associated with the first opening and a second set of tabs is associated with the second opening. Each of the first and second set of tabs are bendable to a lock position preventing rotation of a fastener received within a corresponding one of the first opening and the second opening.

  • GAS TURBINE ENGINE HAVING ENERGY DISSIPATING GAP AND CONTAINMENT LAYER
    Publication number: 20160341070
    Abstract: 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.

  • ENERGY DISSIPATING CORE CASE CONTAINMENT SECTION FOR A GAS TURBINE ENGINE
    Publication number: 20160341075
    Abstract: 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.
