Aeroelastic response dynamics and their corresponding frequency responses at \(U_{crt}\) and \(U_{fold}\) for \(\overline{\omega }\) = 0.67, \(f_{y}\) = 2.25 Hz, \(f_{\alpha }\)= 3.35 Hz. (a) \(\alpha _{pre}(^\circ )\) = \(0^\circ\) , (b) \(\alpha _{pre}(^\circ )\) = \(5^\circ\), (c) \(\alpha _{pre}(^\circ )\) = \(10^\circ\), (d) \(\alpha _{pre}(^\circ )\) = \(15^\circ\), (e) \(\alpha _{pre}(^\circ )\) = \(20^\circ\).
