Aircraft frame elements are highly responsible elements. They are subject to stringent requirements for strength, stability, resource. Often these requirements contradict each other, especially if it is necessary to ensure the minimum mass of the product. However, it is necessary to improve the characteristics of aircraft. Nevertheless, the optimization of the frame has almost exhausted itself. The power frame consists of longitudinal and transverse elements. It is possible to improve the characteristics of structural arrangement by using polymer composite materials based on glass and carbon fibers. This will improve the design characteristics due to high specific properties. In addition, one of the directions is the development of new bioinspired structural layout based on natural analogues. The work is devoted to the actual task of searching and choosing new structural arrangement for the aircraft tail. The paper considers five variants of structural layout, including the classical original design. The advantage of the bioinspired variant in terms of mass and displacement is shown.

“…Проектирование силовой конструкции летательного аппарата (ЛА) всегда являлось сложной комплексной задачей, в которой необходимо учесть множество факторов и аспектов той или иной области науки [1]. Прочность, устойчивость, аэродинамика, влияние температур -это лишь часть основных направлений, затрагиваемых при проектировании [2]. Зачастую необходимо учесть одновременную оптимизацию переменных параметров, описывающих внешнюю форму, внутреннюю структуру, а также отдельные особенности материалов и внутренних механизмов [3].…”

To comply with efficiency in terms of strength, stability and weight of the aircraft, a complex problem for designing a structural layout should be solved. At the same time, it is essential to take into consideration optimization of the shape, quantity, component layout. Now, the main variant of a structural layout is a combination of longitudinal and transverse elements, optimization of which has virtually exhausted itself. The use of polymer composite materials based on glass and carbon fibers, possessing high specific performance compared to metals, makes it possible to improve the performance of a product and additionally optimize a frame structure due to anisotropy of material properties. However, fundamentally innovative structural layouts are needed for further improving properties. It has become practical to create new promising structural layouts due to the development of technologies for manufacturing products from composite materials, including additive manufacturing and 3D printing as well as developing methods of mathematical modeling and computer-assisted design. Bioinspired structures based on natural analogues such as insect wings are attributed to them. The paper is devoted to a highly topical problem of searching and selecting innovative structural layouts. The purpose of the article is to reduce aircraft fin mass while providing structural strength. The paper considers five variants of structural layouts inclusive of the conventional original structure. Aerodynamic loads on the structure were determined by modeling the flow-around process at an assigned flight mode. Stress-and-strain behavior of the structural layout was determined, and the optimal variant of the considered was chosen. The advantage of polymer composite bioinspired structures over conventional metal variants was established. The paper results will be taken into consideration and used in the subsequent optimization of structural layouts and the development of methods for choosing structural layouts.
