“…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]. Fundamentally new mesh schemes [16], as well as structurally optimized curved elements [17] are proposed to meet the stringent requirements for strength, resource, reliability, and minimum weight [18]. Methods and calculations are being developed that take into account numerical optimization [19], the effect of external forces and stress distribution in the structure [20], as well as other parameters.…”

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.

“…In addition, the use of polymer composite materials [11][12] can significantly improve the specific characteristics of the part and the structure as a whole [13]. Structural arrangement with rectilinear loadbearing elements, longitudinal and transverse directions of installation become possible to replace with new curvilinear schemes [14][15] and biosimilar structures [16]. Complex layouts are created using parametric [17], topological optimization [18] methods and are made by 3D printing [19].…”

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.

“…1 -6. Some of these papers adhere to conventional orthogonal layouts of ribs, spars, and stiffeners, 3 others blend the roles of these components through angled and/or curved members, 2,5,6 and others abandon this convention entirely with a complex network of fulland partial-depth members. 1,4 Regardless of how the layout design is conducted, sizing design must be included as well, by optimizing the thickness distribution of the various shell components: ribs, spars, stiffeners, and skins (cover panels).…”

The goals of this work are to 1) develop an optimization algorithm that can simultaneously handle a large number of sizing variables and topological layout variables for an aeroelastic wingbox optimization problem and 2) utilize this algorithm to ascertain the benefits of curvilinear wingbox components. The algorithm used here is a nested optimization, where the outer level optimizes the rib and skin stiffener layouts with a surrogate-based optimizer, and the inner level sizes all of the components via gradient-based optimization. Two optimizations are performed: one restricted to straight rib and stiffener components only, the other allowing curved members. A moderate 1.18% structural mass reduction is obtained through the use of curvilinear members.
