昆虫拍打着翅膀飞行是一种很有吸引力的交通方式。它展示了许多有用的飞行模式，如机动转弯和稳定悬停。在最近的研究中，实验方法和数值模拟方法被成功地应用于对该机理的定量求解。然而，要准确估计机翼与气流相互作用造成的变形是极其困难的。在前人的研究中，我们采用了一种新颖的数值模拟方法--流固耦合分析来分析这一问题，以准确地描述这种交互行为，并实现了对蜻蜓柔性翅膀悬停的定量评价。作为进一步的分析，我们在该方法中加入了机身与机翼相互作用的解，实现了自由飞行仿真。在这里，我们用一个基于实际蜻蜓的模型进行了数值模拟，演示了10rad/S的急转弯。
An insect's flapping flight is an attractive method of transportation. It shows many useful flight modes such as maneuverable turning and stable hovering. In recent studies, experimental methods and numerical simulations have been successfully applied to solve the mechanism quantitatively. However, it is extremely difficult to accurately estimate the deformation of the wing caused by interaction with airflow. In prior studies, we analyzed this problem using a novel numerical simulation, fluid-structure interaction analysis, in order to represent this interactive behavior accurately, and achieved the quantitative evaluation of dragonfly hovering with flexible wings. As an advanced analysis, we added a solution of the interaction between the body and wings to the method, and realized free-flight simulation. Here, we demonstrate a sharp turn of 10 rad/s in a numerical simulation using a model based on an actual dragonfly.
