  • Casing assembly
    Patent number: 10196938
    Abstract: The present invention provides a casing assembly for a gas turbine engine comprising a radially inner casing and a radially outer casing. The assembly further comprises an axial mounting arrangement for mounting the inner casing and outer casing in a fixed axial relationship. The axial mounting arrangement allows radial movement of the outer casing relative to the inner casing such that distortion of the inner casing as a result of engine carcass loads on the outer casing is obviated as the inner casing is radially isolated from the outer casing.
    Type: Grant

  • Gas turbine engine casing and rotor blade arrangement
    Patent number: 6832890
    Abstract: An arrangement for a gas turbine engine comprises a compressor and its surrounding casing. The casing has a generally cylindrical inner surface, one cylindrical section of the inner casing being provided with a circumferential array of recesses. An axially adjacent cylindrical section of the inner casing surface is provided with an abradable lining. The tips of the rotor blades of the compressor are provided with a treated portion at least partly axially aligned with the recesses in the inner casing, the remaining untreated portion of the rotor blade tips being at least partly axially aligned with the lined section of the inner casing.
