Abstract

Modification or retrofit components for an aircraft having wing mounted engines. A replacement wing torque box has thickened spar webs machined with raised bosses around holes in the web to lower stress concentration. The spar caps have the vertical web of their T-shape smoothly tapered spanwise to reduce stress concentration. The spar caps are attached to the webs and wing skins with interference fit rivets. An engine mount has a first space frame attached to the front of the wing torque box, or front spar with a first engine nacelle former disposed at the leading edge of first space forward and extending downwardly below the front spar. A second space frame formed of tension compression tubes extends forward from the first former to a second engine nacelle former. A tension-compression strut connects the first former to the rear spar to spread the loading on the torque box.
