  • Turbine wheel with clamped blade attachment
    Patent number: 10689991
    Abstract: A turbine wheel for use in a gas turbine engine having a plurality of blades attached to a rotor disk. Each blade is formed from a composite comprising ceramic matrix material. The blades each include a root that fits within dovetail slots of the rotor disk and cooperates with a blade retention assembly to couple the blades to the rotor disk.
    Type: Grant
    Filed: July 30, 2018
    Date of Patent: June 23, 2020
    Assignees: Rolls-Royce North American Technologies Inc., Rolls-Royce Corporation

  • Turbine blisk including ceramic matrix composite blades and methods of manufacture
    Patent number: 10280768
    Abstract: In some embodiments, an apparatus includes a disk, a coupling member and a set of blades. The coupling member has a first surface and a second surface, and defines a set of openings between the first surface and the second surface. The first surface is configured to be coupled to the outer surface of the disk. A portion of each blade from the set of blades is disposed within an opening from the set of openings when the first surface of the coupling member is coupled to the outer surface of the disk such that the blade is coupled to the disk.
