Research in the field of improving the performance of aircraft and the search for new fundamental solutions to meet stringent requirements is an actual task. Consideration of three design levels is a possible solution: development of new aerodynamic arrangement, structural frame and individual components. The paper considers the study of the blended-wing-body aircraft and its internal structural frame. The aerodynamic loads were determined, according to which structural layout will be calculated in the future. Classical and curved structural layout are considered, the elements of which are represented by sheet bodies of zero thickness. When designing the structural layouts, the arrangement of the elements, the pitch and the direction of installation of the ribs varied. Based on parametric modeling and calculations, a perspective curved structural force layout of the wing was developed, taking into account the use of composite materials. The advantage of a perspective structural layout over a classical one is presented. Special attention was paid to the process of modeling the laying of composite monolayers in the wing elements. Based on the calculations and optimization of the stacking angles, optimal variations for each of the elements were obtained. The developed design makes it possible to increase the specific characteristics of the wing, providing the necessary structural strength.
