碩士 === 國立成功大學 === 航空太空工程學系 === 85 === This thesis presents the study of maximum range trajectories for an air-to-surface missile. In general, the first-order gradient methos or its modified versions have certain difficulties in convergence. Since the second-order gradient method has faster convergence rate for free terminal time problem, it does have certain superiorities. For this reason, based on the optimal control theory, the second-order gradient method associated with the sweep matrix method is adopted in this thesis to solve the optimal trajectory problems. In order to understand the characteristics of maximum range trajectories of missile, two sets of different missile aerodynamic data are used for analysis and simulations. The maximum range trajectories are first obtained for the flight in vertical plane and then extended for the flight in the three dimensional space. Parametric studies are conducted by varying initial and terminal conditons.
