MAIN BENEFITS OF PRO-COMPOSITE LAYOUTS FOR WING AND FUSELAGE PRIMARY STRUCTURE UNITS

摘要

Novel structures for high-loadedwing/fuselage sections based on pro-compositelayouts allow to obtain weight benefits incomparison with conventional metallic andcomposite structures. These benefits are basedon the four basic principles allowing toharmonize these structure layouts with physicalproperties of current CFRP. Robust designingof pro-composite structures requires novelapproach to design based on solvingmultidisciplinary tasks of different stages ofdesign within the one integrated procedure. Themultilevel algorithm developed in TsAGI on thebasis of this approach allowed to get reliableand promising results for a number ofperspective aircraft wing and fuselagestructures based on frame/lattice pro-compositeconcepts.
