这项工作是我们目前对蜻蜓和蜻蜓飞行的力学、空气动力学和视觉调节控制的理解的综合，并在几个关键领域增加了新的实验和计算数据。它们是：蜻蜓翅膀形态的多样性、滑翔飞行的空气动力学、扑翼飞行中的力产生、空气动力学效率、比较飞行性能以及捕食性和领域性飞行时的追逐策略。通过对几个尺度的解剖学、昆虫空气动力学、神经力学和行为的简要回顾，新数据被设定在背景中。我们通过各种技术实现了一个新的视角，包括机翼地形的激光测绘，机翼精细几何形状的计算流体动力学模拟，使用粒子图像速度计的机翼上和尾流流动模式的定量成像，经典空气动力学理论，现场摄影，红外运动捕捉和实验室环境中自由飞行轨迹的多摄像机光学跟踪。我们的综合方法实现了数据集和子场的新颖合成，集成了飞行的许多方面，从复眼的神经生物学，到与周围流体的气动机械接口，到在巡航和更高能量行为模式下的飞行性能。本文是主题为《在移动的媒介中移动：飞行的新视角》的一部分。
This work is a synthesis of our current understanding of the mechanics, aerodynamics and visually mediated control of dragonfly and damselfly flight, with the addition of new experimental and computational data in several key areas. These are: the diversity of dragonfly wing morphologies, the aerodynamics of gliding flight, force generation in flapping flight, aerodynamic efficiency, comparative flight performance and pursuit strategies during predatory and territorial flights. New data are set in context by brief reviews covering anatomy at several scales, insect aerodynamics, neuromechanics and behaviour. We achieve a new perspective by means of a diverse range of techniques, including laser-line mapping of wing topographies, computational fluid dynamics simulations of finely detailed wing geometries, quantitative imaging using particle image velocimetry of on-wing and wake flow patterns, classical aerodynamic theory, photography in the field, infrared motion capture and multi-camera optical tracking of free flight trajectories in laboratory environments. Our comprehensive approach enables a novel synthesis of datasets and subfields that integrates many aspects of flight from the neurobiology of the compound eye, through the aeromechanical interface with the surrounding fluid, to flight performance under cruising and higher-energy behavioural modes. This article is part of the themed issue ‘Moving in a moving medium: new perspectives on flight’.
