Claim 10:
11. A mounting system for mounting an engine on an aerospace vehicle, the engine comprising a fan case, having an outer portion and an outer periphery, and an engine core arranged along a centerline axis, the mounting system comprising:
a pylon;
a lower forward element to couple a forward portion of the engine core with a lower forward portion of the pylon, and comprising a ring structure encircling the forward portion of the engine core to support the fan case and the engine core, wherein when the ring structure is attached to independently support the fan case and the engine core, one of the fan case or the engine core is removable without removing the other, with the lower forward element resisting an engine torque (Mx) during operation of the engine;
one or more lateral linkages extending from the lower forward element to extend laterally between the lower forward element and the forward portion of the engine core, with the one or more lateral linkages limiting side-to-side (yaw) deflections of the fan case with respect to the engine core during operation of the engine;
an upper forward element spaced laterally apart from the lower forward element, extending from an upper portion of the pylon to couple the outer portion of the fan case with the upper portion of the pylon;
an aft element spaced aftwardly apart from the lower and upper forward elements, extending from an aft portion of the pylon to couple an aft portion of the engine core to the aft portion of the pylon, and
an interconnect structure extending from the lower forward element to the upper forward element and extending along a forward surface of the pylon,
wherein the pylon, the lower forward element, the one or more lateral linkages, the upper forward element, and the aft element do not extend vertically beyond the outer periphery of the fan case when coupled to the engine.
