Abstract

With the rapid development of unmanned aerial vehicle (AV) technology, the flapping wing vehicle (FL) is becoming a research frontier in the field of AV due to its advantages of low noise, high maneuverability and biomimetic concealment. In this paper, Anuses Fluent is used to analysis the three-dimensional flow field of a butterfly-like flapping wing vehicle to optimize its aerodynamic performance. A three-dimensional model of the butterfly-like wing-fluttering vehicle is constructed using the waterfall butterfly as a prototype, and its aerodynamic characteristics are simulated under different flutter amplitudes and frequencies. Through the comparative analysis, the effects of flutter frequency and amplitude on lift and drag are revealed, which provides theoretical support for the design of the flapping aircraft and guides the performance optimization. The main innovation of this study is to extract the optimize design reference through simulation analysis, and to lay a theoretical foundation for the performance improvement of the butterfly-like aircraft.
