Abstract: Estimation of aeroelastic damping for a very flexible high-aspect-ratio wing using wind-tunnel test data is presented in this work through the comparison of four different methods: half-power, half-quadratic gain, an adapted ...

Abstract: This paper proposes a nonlinear disturbance observer (NDO)–based sliding mode control (SMC) method to the problem of stall flutter suppression for a revised Leishman–Beddoes (L–B) model. To capture accurate aerodynamic ...

Abstract: High aspect ratio flexible wings are of increasing interest for enhancing the aerodynamic efficiency of future designs. However, they often exhibit nonlinear dynamic behavior, complicating both testing and analysis. This ...
