    Abstract: An airframe for a tiltrotor aircraft (10) includes a wing airframe (24; 106) including a rib (20a, 20b; 124a, 124b), a fuselage airframe (26; 102) including a fore-aft overhead beam (28a, 28b; 126a, 126b) and a cradle support assembly (56a, 56b; 110a, 110b). The cradle support assembly (56a, 56b; 110a, 110b) includes a forward wing support (146a, 146b) coupled to the fore-aft overhead beam (28a, 28b; 126a, 126b) and the wing airframe (24, 106) and an aft wing support (148a, 148b) coupled to the fore-aft overhead beam (28a, 28b; 126a, 126b) and the wing airframe (24, 106). The rib (20a, 20b; 124a, 124b), the fore-aft overhead beam (28a, 28b; 126a, 126b), the forward wing support (146a, 146b) and the aft wing support (148a, 148b) are substantially aligned to form a wing-fuselage integrated airframe beam assembly (32a, 32b; 108a, 108b) to support the wing airframe (24, 106).

    Abstract: In one aspect, there is a method of making a pre-cured laminate having a total number of plies in a mold (190), the mold (190) having a periphery (198) defined by a forward edge (198a), an aft edge (198b), and outboard ends (198c, 198d). The method includes selecting a first plurality of resin impregnated plies (173) that continuously extend beyond the periphery (189) of the mold (190), the first plurality of resin impregnated plies (173) includes at least 50 percent of the total number of plies; laying the plies in a mold (190); compacting the plies in a mold (190); and pre-curing the plies to form a pre-cured laminate, which can extend beyond the periphery (198) of the mold (190). In an embodiment, a pre-cured laminate includes a first plurality of resin impregnated plies (173) that continuously extend beyond the periphery (198) of the mold (190), the first plurality of resin impregnated plies (173) includes at least 50 percent of the total number of plies.
