The performance of ground-based optical structures is highly sensitive to external environments, such as airflow in open space. In this paper, initial aerodynamic data due to ambient air flow were analyzed in optical models designed through knowledge-based design algorithm, and dynamic data acting on optical structures in turbulent flow with velocity of 50m/s were analyzed to present the initial shape design conditions of the structures. The simulation results showed that the maximum pressure, minimum pressure, and maximum differential pressure acting on the mirror are directly proportional to the sweep angle.
