  • Fan track liner designed to yield next to fan case hook
    Patent number: 10024191
    Abstract: A containment system for a gas turbine engine includes a fan track assembly for use with a containment case. The fan track assembly includes a body of collapsible material that is positioned within a cavity of the fan case, and voids are provided for providing space in the event of a catastrophic blade failure. Various configurations of the fan track liner assembly are provided along with various mounting methodologies for securing the track liner assembly to the fan case of a gas turbine engine.
    Type: Grant
    Filed: September 5, 2013
    Date of Patent: July 17, 2018
    Assignee: ROLLS-ROYCE CORPORATION

  • Aerodynamic fairings secondarily attached to nosecone
    Patent number: 9481448
    Abstract: An aerodynamic fan nosecone for a gas turbine engine is provided and includes a fan nosecone that may be made of composite material. To improve airflow transition to the blade members, aerodynamic fairings are provided and are secured to an exterior surface of the nosecone which enhances fuel economy. The fairings may be secured to the nosecone by various methods, including providing for the fairings to be changed out and replaced with other fairings on the same nosecone assembly.

  • Balance weight
    Patent number: 8322991
    Abstract: A balance weight adapted to be assembled to a nose cone assembly of a turbine engine for improving a balance of the nose cone assembly is disclosed herein. The balance weight is one-piece and formed from a plurality of different materials including at least first and second materials. The first and second materials are arranged substantially heterogeneously relative to one another such that said first and second materials are separate from one another and fixed together.
