Patent ID: 7950605

Claim:
An engine mounting system for use in rotorcraft having a rotor, an engine, a pylon assembly, and a gear box operably associated with the engine and the rotor, the engine mounting system comprising: a forward mount for coupling the engine to the gear box, the forward mount comprising: an annular base portion having a first attachment flange, the first attachment flange configured for coupling to the engine; an annular input housing having a second attachment flange, the second attachment flange configured for coupling to the gear box; and an integral flexure region forming a transition between the base portion and the input housing; an aft mount for coupling the engine to the pylon assembly, the aft mount comprising: a fitting disposed in a plane generally transverse to a longitudinal axis of the engine; wherein the aft mount is configured to avoid reaction of induced rotor torque, such that only the forward mount reacts torque, thereby eliminating torsional redundancy in the engine mounting system, so as to thereby eliminate torque from the rotor from being induced into the engine by the aft mount; wherein at least one physical characteristic of the forward mount is selectively tailored to tune a dynamic response of the engine.
