  • Deformed forging
    Patent number: 7536895
    Abstract: A method of manufacturing a forging for forming a split casing comprising the steps of creating a forging, for example, by a ring rolling process and then deforming the forging by compressing it along a first axis and/or extending it along a second axis.

  • Engine casing with slots and abradable lining
    Patent number: 6905305
    Abstract: An engine casing (16) encloses a rotor (15) and has a wall the inner surface (17) of which has slots (20) therein. An abradable lining (19) is attached to the inner surface (17) of the wall and extends across the slots (20). The abradable lining (19) is fluid permeable so that in operation a fluid passes through the lining (19) and recirculates in the slots (20). Recirculation of the fluid within the slots (20) increases the aerodynamic efficiency of the rotor (15).
