Patent ID: 7654075

Claim:
A static structure for a gas turbine engine, the structure comprising: a ring and a hub aligned along a principal axis X-X, the hub being disposed radially within the ring; a plurality of vane elements and strut members between the ring and the hub, wherein at least some of the vane elements are angled in a first direction so as to be sloped with respect to the principal axis and also in a second direction so as to have a tangential inclination between the ring and the hub, the ring and the hub being subject to differential rotation in use causing roll torque and the tangential inclination of the vane elements being arranged to restrain said roll torque, and at least some of the strut members being sloped with respect to the principle axis so as to oppose and at least in part brace a differential axial movement associated with the axial lean of the vane elements in use.
