Abstract
An effective method and fast modeling in vibration and flutter analyses of low-aspect-ratio composite wings and wings with a control surface in a subsonic flow are proposed. An equivalent plate method is used for structural modeling. The doublet point and the U - g methods are applied to calculate unsteady aerodynamic loads and flutter analysis, respectively. The obtained results are in good agreement with the literature data.
