- Abstract
- This article examines the design and formation of the structural geometry of an aircraft wing. In general, the aircraft structure is subject to complex, time-varying loads. The wing is the primary and most informative component of the aircraft. Generally, the wing's centers of pressure, rigidity, and mass do not coincide. It is concluded that when forming the wing's structural geometry, one should strive to ensure that the center of mass of the wing's cross-section is significantly ahead of the center of pressure, that the center of pressure of the wing's cross-section is ahead of the center of rigidity, and that the center of rigidity and the center of pressure are aligned with the center of mass. The paper presents design and layout solutions that achieve the desired relative positions of three characteristic wing points. These recommendations have been implemented using additive technologies in the wings of modern unmanned aircraft.
