Aircraft engine pylon to wing mounting assembly

An aircraft wing assembly comprising an aircraft wing having leading and trailing edges and a pylon mounting assembly for mounting an engine to the aircraft wing, wherein the pylon mounting assembly comprises:

• an upper pylon connection member which extends forwardly of the leading edge of the aircraft wing relative to an aircraft travel direction, and
• a lower pylon connection box having an elongate axis along the aircraft travel direction, wherein
• the upper pylon connection member and the lower pylon connection box respectively include a forward opposed upper and lower forward connection lobes, and wherein
• the wing box of the aircraft wing and the lower pylon connection box respectively include at least one additional opposed pair of upper and lower additional connection lobes rearwardly positioned relative to the forward pair of opposed upper and lower connection lobes, and wherein
• the forward and additional opposed pairs of upper and lower connection lobes are aligned with the elongate axis of the lower pylon connection box;
• and wherein
• the upper forward connection lobe of the upper pylon connection member is positioned at and extends forwardly of a terminal end of the upper pylon connection member;
• and wherein
• the lower forward connection lobe of the lower pylon connection member extends upwardly from the lower pylon connection member;
• and wherein
• at least a first one of the forward and additional pairs of upper and lower connection lobes includes a pin connection to restrict degrees of freedom thereat along an x-axis and a mutually perpendicular z-axis, and wherein
• at least a second one of the forward and additional pairs of upper and lower connection lobes includes a connection rod to restrict degrees of freedom thereat along the z-axis, and wherein
• each of the pin connection and the connection rod comprises a fuse pin capable of rupturing and breaking away in response to a separatory force exceeding a nominal design force to thereby allow separation of the lower pylon connection box from the upper pylon connection member and the wing box of the aircraft wing.
