Ultralight structurally optimized carbon fibre reinforced polymer composite wing designing based on parametric modelling and topology optimization

The passenger aircraft wing is an extremely complex object, especially in design, in which it is necessary to take into account many different factors, physical processes and phenomena both in individual areas of science and engineering, and at their junction. The main enlarged areas and issues that are solved during the development of wings include aerodynamics, aeroelasticity, strength, stability, and manufacturability. All this causes significant time and labour costs, especially at the stage of design calculations. In this connection, the urgent task of compiling a universal integrated methodology for designing a wing of polymer composite materials, which allows to accelerate and facilitate the selection of design parameters at the stage of outline design. The methodology being developed is tested on the passenger aircraft wing and takes into account the choice of the geometric shape of the wing, taking into account optimal aerodynamics and minimizing the operating loads, determining the position of the main power elements providing the necessary structural strength, as well as calculating the main structural parameters of individual polymer composite elements.
