Selection and justification of polymer composite wing structural arrangement using parametrical modeling

Abstract

Abstract Currently, due to the increase in air traffic, the need for modern reliable airliners is increasing, the requirements for which are constantly growing. One of the options for meeting these requirements is the use of polymer composite materials (PCM) in the structure, in particular in the wing. This article is devoted to the urgent task of designing a polymer composite wing power circuit within the framework methods of designing developing. The modeling, calculation and analysis of ninety variants of the wing structural and power schemes. The rational geometric parameters of the primary structural member arrangement are established, including the step and installation direction of ribs, stringer, spars, providing the greatest margin of safety factor. The skin power element is considered in detail. The stringer shape and material based on the calculations made are justified. The work is part of the methodology for designing a polymer composite wing.
