The aerodynamic efficiency is low

the energy consumption is high for flapping to micro flapping wing used traditional mechanism. The bionic flapping wing driven by piezoelectric materials effectively integrates flapping mechanism and the wings. It is not only to save weight but also to be the task of deformation and strong adaptive ability

high aerodynamic efficiency

low energy consumption characteristics of mechanism. It is to establish finite element model of piezoelectric flapping wing by PCL language. The structure simulation of piezoelectrically driven bionic flapping wing is carried out with the size of the aerodynamic force of the experimental data. The piezoelectrically driven bionic flapping wing is developed by using simulation results. The studies show flapping frequency of bionic flapping wing is improved obviously after using piezoelectric actuator.The piezoelectric patches can effectively control wing bending and torsion deformation

and help to improve aerodynamic efficiency of flapping wing.
