摘要

A design study was conducted to determine the potential weight savings and performance increase from advanced matallic materials for wing skin panels. The materials included aluminum lithiujm 2090-T83, ARALL-3 (aramid-reinforced aluminum laminate) and GLARE-2 (glass-aluminum-reinforced epoxy). An executive business jtt airplane was taken as a baseline in the design rrade study. This wing has mechanically attached stringers to stiffen the panel against compressive and shear loaidng. The advanced skin materials were designed into an advanced wing box; advantage was taken of th eincrease in strength and stiffness. The design, fabrication, and testing of the test panels were done at Textron Aerostructures. Two 2090-T83 aluminum-lithium skins with 7075-T6511 extruded Z-shaped stringers bonded to them were used for the evaluation of the upper wing cover structure. One, panel had five bays, the other four. The respecive widths were 59.39 cm (23.38 in.) and 49.48 cm (19.48 in.). The overall length was 125.43 cm (49.38 in.) for all panels. Two ARALL-3 and two GLARE-2 compression panels with the same type of stringers were designed to evaluae the lower wing cover structure. The laminate panels were all five-stringer bays 78.74 cm (31 in.) in width.
