摘要

摘要: 针对扑翼飞行比固定翼飞行气动特性更为复杂、升力计算更加困难问题，从绕流物体的基本气动特性出发，将飞行升力分成绕流升力与阻流升力。分析了扑翼飞行模式下绕流升力与阻流升力作用特点，解释了动物飞行中绕流升力与阻流升力的变化规律。在此基础上，建立了扑翼飞行运动模型，推导出扑翼最大绕流升力与阻流升力理论估算模型。实验算例表明，分类升力估算方法是可行的，绕流升力与阻流升力占比与扑翼实际飞行规律趋势一致。

Abstract: It is difficult to theoretically calculate lift of flapping wing flight as the aerodynamic feature of flapping wing is more complex than fixed wing flight. Based on the basic aerodynamic characteristics of an object flowed around by air, the total lift of flapping wing flight was divided into lift of flow around wing(LFAW) and lift of flow dragging wing(LFDW) in this paper. The acting mechanism and change rule of LFAW and LFDW in flapping wing flight were further analyzed and illustrated. After establishing motion model of flapping wing, theoretical calculating models of maximum LFAW and LFDW were further given. Case study shows that not only the classified lift method was feasible, but the proportion of LFAW and LFDW during fly test was consistent with the change rule of actual animal flight.
