Abstract: In a mounting for a gas turbine engine, the engine is pivotally mounted about its center of gravity to an aircraft support structure by means of a pair of radially outwardly extending trunnions. Each trunnion is connected to a central conical section of engine casing by means of an axially extending intermediate support member. The support member is secured to the downstream end of the conical casing section at an axial location offset from the trunnion. During operation distortion of the less stiff conical section is reduced by virtue of the resultant shear force distribution across the casing.
