Abstract
A high bypass turbofan engine is coupled to a wing strut by a spaceframe thrust linkage. The linkage transfers the axially oriented thrust-induced loads to the strut along the axial horizontal centerplane of the engine. The inlet to the engine is supported by a combined triangular and tetrahedral linkage system which suspends the inlet and transfers axial, vertical, and side loads directly from the inlet to the strut. The inlet is coupled to the engine fan case via a plurality of fluid-filled piston and cylinder assemblies that transmit only axially oriented loads from the inlet to the fan case. Additionally, the linear actuators for the annular thrust reverser are coupled to the inlet so that the axial thrust reversing loads are first transferred to the inlet, from which the axial loads are effectively transferred to the fan case along the engine centerline and hence to the strut via the spaceframe linkage.
