| Abstract: | This paper studies the optimal trajectories for noncoplanar circular orbital transfer aided by the aerodynamic forces.The optimization performance index is to maximize the orbital plane change, and the optimal lift and bank control law are obtained. In this paper, a search method of the parameters for the optimization problem is presented, which is advantageous to solve this problem.Finally, the numerical results are analyzed and compared with other transfer modes. It is shown that, for certain conditions, the use of aeroassisted orbital transfer is significantly advantageous. |
