The objective of this study is to clarify the principle of the most stable position in the skydiving freefall. As the first step, the simulation method to analyze the dynamic behavior for freefall has been developed by the authors. In this report, an optimizing calculation to maximize an objective function with respect to the stability in the freefall is conducted. It is found that the most stable position becomes arched one. Next, the simple configuration that consists of 20 cylinders is optimized, and the angle to maximize restoring moment about each cylinder element is calculated and compared with optimized angle.
