叶片单元建模为估计昆虫飞行过程中产生的气动力提供了一种快速的分析方法，但这种模型尚未通过使用自由飞行的昆虫记录的运动学数据进行严格的测试。这在很大程度上是因为缺乏详细的自由飞行运动学数据，但也因为现有叶片元件模型的分析局限性意味着它们无法纳入昆虫飞行过程中翅膀和身体的复杂三维运动。在这里，我们提出了一个叶片单元模型，该模型具有经验拟合的气动力系数，该模型包含了机动食蚜蝇的完整三维机翼运动学，包括其翅膀的扭转变形。这两个自由参数被拟合到一个包含N = 26541翼拍的大型自由飞行数据集上，拟合模型捕获了约80%的矢状面平均翼拍力变化。我们通过对数据进行子采样来测试模型的稳健性，并发现在包含10%飞行序列的子样本中参数估计几乎没有变化。我们提出的模型的简单性和通用性使得它可以很容易地应用于其他昆虫的运动学数据集，也可以用于昆虫飞行动力学的研究。
Blade element modelling provides a quick analytical method for estimating the aerodynamic forces produced during insect flight, but such models have yet to be tested rigorously using kinematic data recorded from free-flying insects. This is largely because of the paucity of detailed free-flight kinematic data, but also because analytical limitations in existing blade element models mean that they cannot incorporate the complex three-dimensional movements of the wings and body that occur during insect flight. Here, we present a blade element model with empirically fitted aerodynamic force coefficients that incorporates the full three-dimensional wing kinematics of manoeuvring Eristalis hoverflies, including torsional deformation of their wings. The two free parameters were fitted to a large free-flight dataset comprising N = 26 541 wingbeats, and the fitted model captured approximately 80% of the variation in the stroke-averaged forces in the sagittal plane. We tested the robustness of the model by subsampling the data, and found little variation in the parameter estimates across subsamples comprising 10% of the flight sequences. The simplicity and generality of the model that we present is such that it can be readily applied to kinematic datasets from other insects, and also used for the study of insect flight dynamics.
