This paper presents a parametric study on the aeroelasticity of cantilever wings equipped with Flared Hinge Folding Wingtips (FHFWTs). The finite element method is utilized to develop computational, low-fidelity aeroelastic model. wing structure modelled using Euler–Bernoulli beam elements, and unsteady Theodorsen’s aerodynamic strip Theory used for load predictions. PK estimate boundaries. mod...

During the process of span extension for an aircraft wing equipped with a telescopic morphing mechanism, aspect ratio increases, and hence, geometrical nonlinearities might become more significant. In this regard, paper aims to investigate effect structural nonlinearity on aeroelasticity wings using exact fully intrinsic equations first time. Furthermore, effects various parameters such as thru...

Abstract Aeroelasticity studies the static and dynamic interaction between structural deformation fluid forces. As a result, aeroelasticity is usually divided into three parts: aerodynamics, response, dynamics with statics as special case. Instabilities may occur to this (feedback) that lead failure and, even when no instability occurs, degradation or improvement of system performance. There ar...

We study solvability of the generalized Possio integral equation a tool in analysis of a boundary value problem in 2D subsonic aeroelasticity with the Kutta-Joukowski condition ”zero pressure discontinuity” ψ(x, 0, t) = 0 on the complement of a finite interval in the whole real line R. The corresponding problem with boundary condition on finite intervals adjacent to the ”chord” was considered i...
