ABSTRACT:
A static structure is provided such as that used as an engine structure30within a gas turbine engine. A structure30comprises a hub or core33with a concentric ring or casing32. The hub33and casing32are secured together through spoke or vane elements31which are sloped axially and tangentially relative to a principal axis X-X. In such circumstances any roll torque reaction caused by differentially rotating hub and ring motions is retained by the tangential inclination of the spokes or vanes whilst axial sloping of these spokes or vanes31and axially sloping of the struts34creates bracing in the direction of the principal axis X-X. In such circumstances essentially robust triangles are formed radially and longitudinally respectively each comprising spokes or vanes31and struts34secured at axially spaced locations on the hub or core33.
