这项研究的目的是对飞盘飞行的计算机模拟进行验证。飞盘，广为人知的FrisbeeTM，是以旋转的方式抛出的，因为它飞行稳定。飞盘的飞行特性与其他飞行运动材料相同。飞盘利用机翼效应在空中保持升力和滑行。然而，在特定的条件下，圆盘的移动方向发生了急剧的变化。为了解释这一现象，需要对圆盘运动进行精确的模拟。在本研究中，完成了飞盘的计算机模拟。在模拟之前，为了进行模拟，在风洞试验中测量了作用在圆盘上的三轴向力和力矩。为了验证仿真结果，作者利用运动捕捉系统进行了实验，获得了真实的飞盘运动参数。
The purpose of this study was validation of a computer simulation on the flight of the flying disc. The flying disc, widely known as the FrisbeeTM, is thrown with rotation for its stable flight. The flight characteristics of the flying disc were identical in comparison with other flying sports materials. The flying disc can keep its lift and glide in the air by the wing effect. However, the traveling direction of the disc was steeply changed in particular conditions. In order to explain this phenomenon, the precise simulation of the disc movement is necessary. In this study, a computer simulation of the flying disc was accomplished. In advance of the simulation, both the three-axial forces and moments acting on the disc were measured in a wind tunnel test for the simulation. For the validation of the simulation results, the authors conducted an experiment using a motion capture system to obtain real flying disc kinematical parameters.
