Claim 1:
2. The gas turbine engine according to claim 1, wherein
the roll-torque transfer formation has a first torque link pivotally joined at a lower end thereof to one side of the core casing, a second torque link pivotally joined at a lower end thereof to the other side of the core casing, and a torque beam which extends across the top of the core casing and which is pivotally joined at opposite ends of the beam to respective upper ends of the first and second torque links;
the roll-torque transfer formation further has a support bracket which is configured to attach to the pylon at the mid attachment position, the support bracket pivotally connecting to the torque beam at two laterally spaced apart support positions between the opposite ends of the beam; and
a central portion of the torque beam between the support positions forms a hinge joint such that an upward vertical load transmitted through one of the torque links and a simultaneous downward vertical load transmitted through the other torque link are reacted at the support positions to transfer roll torque from the core casing to the pylon, whereas simultaneous movement of both torque links in the same vertical direction hinges the hinge joint to substantially prevent vertical loads being reacted at the support positions.
