“…The fuselages of various aircraft and their components are being developed [2]. Various optimization methods [3], including topological [4][5], are used to determine the configuration of the force set and the main elements from metal-matrix [6] and polymer [7] composite materials. Various loading conditions [8] and features in experiments [9] are taken into account.…”

Currently, the industry of unmanned aerial vehicles (UAV) is actively developing. They perform a wide range of different civilian and military tasks. Depending on the task, stringent requirements are imposed on the design, but the key ones are low weight, high strength and survivability. Satisfying these requirements will increase the payload mass and extend the life of the product. This can be ensured by the use of polymer composite materials (PCM) based on carbon fibers and new structural arrangement. This is especially true for the main element of the UAV frame –the fuselage. The work is devoted to an urgent task –the development of a new UAV composite structural layout. Structural-optimized structures are considered: bioinspired, auxetic, grid structures. A comparison of the developed options with the classical structure of the frame is carried out. A variant that exceeds the classical layout in terms of mass and strength up to 25% is selected. Main layout parameters are determined.

“…However, fundamentally new design solutions, bioinspired structures based on natural structures [7], became possible only with the development of manufacturing technologies in the field of additive manufacturing and 3D printing [8][9][10]. Methods of mathematical modeling [11], interdisciplinary design [12], and topological optimization [13,14]. For one of the main aggregates of the aircraft -the wing, approaches to the creation of periodic structures based on topological optimization are being formed [15].…”

Developing trends in designing and manufacturing products made of polymer composite materials allow us to create previously unattainable structures. These include bioinspired structural layouts inspired by objects of nature, for example, the wings of insects, plants, and others. In turn, the structural layout of the wings of aircraft has reached its limit in terms of optimization in its classic form. The work is devoted to an urgent task –the choice of a bioinspired layout for an aircraft wing. A comparison of classic structural arrangement with a bioinspired structure is carried out. The total number of options considered is 14. The structure of the bioinspired wing was chosen based on the action of the load and stress distribution according to the results of preliminary calculations inspired by insect wings. The advantage of wings of a bioinspired design over classical ones by weight up to 32% is shown. The results of the initial stage of studies of bioinspired wings are presented.
