Abstract

The present study aimed at obtaining torsional stiffness, bending stiffness and stiffness center position of full composite wing using thin wall structure mechanics theory. The influence of stringer layout on wing integer structure stiffness was furthermore investigated. It was found that wing section stiffness was influenced by stringer layout and dimension. The best spacing of stringer was within the range from 130 mm to 150 mm, at the same time, stringer stiffness had more change by the differences of its numbers. The study of this paper provided important support for structural design and aeroelastic analysis on composite wing.
