Abstract
The optimal, maximum range trajectory for a glider in ground effect and wind shear has been analyzed using numerical methods and analytical techniques based on optimal control theory. This investigation models the glider's nonlinear dynamics and includes both ground effect and wind shear models. An optimal control problem is formulated to maximize downrange distance and it includes state-variable inequality constraints. The problem is then solved using an algorithm that implements a Legendre pseudospectral collocation method. The results show that the glider's optimal trajectory follows an energy-efficient trajectory, the altitude path with the lowest energy height consumption in ground effect and tail-wind shear. The numerical results are presented within.
