20120134834 | ASYMMETRICAL ROTOR BLADE SLOT ATTACHMENT - A gas turbine engine includes a disk having an annular hub circumscribed about a centerline with an annular web extending radially outward from the hub to an annular rim. A multiple of slots extend generally axially through the rim and at least one of the multiple of slots having an asymmetric slot root for lower stress and higher service life. | 05-31-2012 |
20120177485 | COVER PLATE WITH INTERSTAGE SEAL FOR A GAS TURBINE ENGINE - An air seal assembly for a gas turbine engine includes a first cover plate with a radially extending knife edge seal defined about and axis of rotation. The first cover plate is mountable to a first rotor disk for rotation therewith, the first radially extending knife edge seal interfaces with a vane structure. A second cover plate with a second radially extending knife edge seal defined about the axis of rotation, the second cover plate mountable to the second rotor disk for rotation therewith. The second radially extending knife edge seal interfaces with the vane structure. | 07-12-2012 |
20120177495 | MULTI-FUNCTION HEAT SHIELD FOR A GAS TURBINE ENGINE - A rotor disk assembly for a gas turbine engine includes a rotor disk with a circumferentially intermittent slot structure that extends radially outward relative to an axis of rotation. A heat shield has a multiple of radial tabs engageable with the circumferentially intermittent slot structure to provide axial retention of the cover plate to the rotor disk. | 07-12-2012 |
20120244004 | COMPONENT LOCK FOR A GAS TURBINE ENGINE - A lock assembly includes a lock body with an undercut slot which receives a retaining wire of a polygon shape. | 09-27-2012 |
20130336785 | ROTOR ASSEMBLY WITH INTERLOCKING TABS - A rotor assembly includes a first rotor having first tabs and a second rotor that is arranged coaxial with the first rotor and that includes second tabs that are interlocked with the first tabs. A retainer locks the first tabs and the second tabs together. | 12-19-2013 |
20140000084 | TOOL FOR ROTOR ASSEMBLY AND DISASSEMBLY | 01-02-2014 |
20140109548 | HIGH PRESSURE ROTOR DISK - A rotor disk for a gas turbine engine is disclosed and formed to enable operation at high rotational speeds in a high temperature environment. The rotor disk is formed to include a bore, a live rim diameter and an outer diameter related to each other according to defined relationships. | 04-24-2014 |
20140290021 | TOOL FOR ROTOR ASSEMBLY AND DISASSEMBLY - An apparatus includes a body, a driver, a plurality of shafts, and a plurality of arms. The body is configured for insertion into a component and the driver is adapted for movement relative to the body. The plurality of shafts extend through the body and are connected to the plurality of arms. The tool is configured such that contact by the driver against the shaft rotates the plurality of shafts to pivot the plurality of arms. | 10-02-2014 |
