Designing the wing of a modern airliner made of polymer composite materials (PCM) is considered a complex task that requires taking into account not only operating conditions, engine placement features, but also anisotropy of material characteristics, production technology. The use of PCM makes it possible to increase the mass efficiency of the airliner structure, but it leads to an increase in the complexity and duration of the preliminary design stages, which, due to high competition, is highly undesirable. The universal technique developed by the authors allows not only to facilitate the design process of the ultralight wing, but also to reduce time costs. The work based on the proposed methodology shows the process of developing the geometric appearance of an ultralight carbon fiber wing, taking into account operational loads, substantiating the structural-arrangement and individual load-bearing elements made of carbon fiber. |
