Abstract: Flapping-wing micro air vehicles (FMAV) are new conceptual air vehicles that mimic the flying modes of birds and insects. A new dynamic analysis and design method for FMAV is proposed in the background of engineering application. Based on statistics and analysis of flying parameters of birds, the biomimetic formulas are brought forth and original FMAV design is carried out. According to the biomimetic results, the transmission layout, power scheme and total structure of FMAV are designed, and the dynamic properties of FMAV are studied by dynamic analysis method that includes kinematic, aerodynamic and structure dynamic analysis. Then the parameter optimization design is proceeded following dynamic analysis to reach the optimum performance of FMAV. Airplane prototype and wind tunnel experiments verify the effectivity and feasibility of this method. The results of research are helpful to the design, fabrication and application of FMAV.
