Model simplification, nonlinear aeroelastic analysis and further optimization design of HALE aircraft

Caption

Considering the characteristics of large slenderness ratio structure, it is reasonable to simplify the dynamics of a HALE aircraft as the plunge, pitch, and flap motions of a planar airfoil. The dynamic behavior of the 3-DOF airfoil can be obtained via nonlinear aeroelastic analysis. The theoretical results are beneficial for the optimization design of HALE vehicles under coupled nonlinear conditions.
