Abstract

In this paper, the impact of varying the sweep angle of the spar and the rib orientation on wing structural deformation is investigated and related to a beam model. 3D Finite-Element wing wind tunnel models with varying wing sweep angle and rib orientation are considered. The wing models tip displacement and tip twist under static tip loads and aerodynamic loading are considered as well as the wing’s natural frequencies, aeroelastic instability speed and maximum root bending moment during a gust encounter. A framework to characterise Euler-Bernoulli beam properties on wings with geometric coupling is then developed and validated to relate the stiffness and bend/twist coupling parameter to the full FE models.
