Paper Abstract

This paper will present the effect of the vehicle dynamics of an aircraft with shape changing wings. The aerodynamic forces will be calculated using a 3D aerodynamic model developed that utilizes a modern adaptation of Prandtl's lifting-line method which can be used for wings of arbitrary camber, sweep and dihedral. The method will be applied to analyze the dynamics of different out-of-plane wing configuration of interest for morphing aircraft application. One particular wing configuration of interest is the wing configuration that has two sections, an out-of-plane dihedral section and a horizontal configuration, like a V shape wing configuration. An investigation as to how the partial dihedral will affect the dynamics of the vehicle, in turning is performed. A Comparison for symmetric and asymmetric wing configurations is performed.
