Abstract

Abstract: The frame (truss) layout based on the hybrid metal‐composite rod elements is proposed for weight saving of the primary aircraft structures. It is proposed to provide the durability of rod elements by protection system against impacts and environment. The algorithm of designing the structure with frame layout has been developed on the basis of 2‐level approach. Fast strength analysis methods based on automated numerical models have been developed. The results of comparative weight estimations of frame and conventional wing box structure of prospective civil aircraft are presented.
