Abstract

This paper presents a numerical method to calculate the aerodynamic force and torque for the complex spacecraft considering components blocking. The Square Division Method (SDM) is applied to analyze and therefore evaluate the space station´s structure. The efficiency and accuracy of the SDM are investigated in the simulation section primarily. Then major structures of the space station are analyzed and evaluated by testing their performance in the Local-Horizontal-Local-Vertical (LVLH), Inertial-Oriented-Attitude (IOA) and Torque-Equilibrium-Attitude (TEA) modes. The long-term momentum accumulation is chosen as the criterion to evaluate appropriate flight modes for each structure. Based on the simulation results, appropriate operation modes are decided for each structure.
