This paper investigates the inertial force effect on nonlinear aeroelasticity of flexible wing aircraft. The geometric are nonlinearity due to rotational and tension stiffening. The effect of large bending deflection will also be investigated. Aeroelastic analysis will be conducted for a truss-braced wing aircraft concept with nonlinear effect of large bending deflection and inertial force coup...

This paper investigates the effects of nonlinear large deflection bending on the aerodynamic performance and aeroelasticity of a high aspect ratio flexible wing. A nonlinear large deflection theory is developed for aeroelasticity to account for large deflection bending. An analysis is conducted to compare the nonlinear bending theory with the linear bending theory. The results show that the non...

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...

The identification of nonlinear aeroelastic systems based on the Volterra theory of nonlinear systems is presented. Recent applications of the theory to problems in experimental aeroelasticity are reviewed. These results include the identification of aerodynamic impulse responses, the application of higher-order spectra (HOS) to wind-tunnel flutter data, and the identification of nonlinear aero...

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...
