Selection and Justification of the Advanced Bioinspired Structural Force Layout of a Wing Made from the Polymer Composite Materials

Abstract

Improving characteristics of an aircraft becomes possible due to not only raising the aerodynamic performance and developing the new layouts, but also due to optimization of the power frame. In particular, it is possible to improve the airframe specific characteristics by using the new advanced polymer composite materials, as well as by developing and introducing the fundamentally new structural force layouts. Such layouts include the advanced biosimilar structures. In turn, the developing production technologies are able to provide manufacture of such structures. The paper considers advanced versions of the structural force layouts of the classical and biosimilar type making it possible to reduce the mass without losing the strength indicators. Seven classical layout schemes were developed with rectilinear and curvilinear force elements, pronounced spars, ribs and walls, as well as seven schemes, where the elements installation direction and shape were based on configuration of the insect wings. Effects of the load and stress distribution according to the results of preliminary calculateions were taken into account. Advantage in weight of the biosimilar wings compared to the classical wings was ~ 32 %. This work is the initial stage in the promising structural power layouts. The results obtained would allow further simulating the wing complex structure
