1. A gas turbine engine including a support structure for attaching the engine to an aircraft pylon at front, mid and rear attachment positions thereof;
wherein the engine further includes:
an engine core comprising a turbine, a compressor, and a core shaft connecting the turbine to the compressor; and
a core casing surrounding the engine core; and
wherein the support structure includes:
a front mount joined to the engine and configured to attach to the pylon at the front attachment position and a rear mount joined to the core casing and configured to attach to the pylon at the rear attachment position, each of the front and rear mounts being configured to transfer lateral and vertical loads from the engine to the pylon, and the rear mount being spaced from the front mount such that yaw and pitch torques are also transferred from the engine to the pylon through the front and rear mounts;
an axial load transfer formation configured to transfer axial loads from the engine to the pylon; and
a roll-torque transfer formation joined to opposite lateral sides of the core casing and configured to attach to the pylon at the mid attachment position to transfer roll torque from the core casing to the pylon.
