Development of piezo-actuated wings for flapping wing Micro Air Vehicle

摘要

Flapping wing concept is emerging area in the Micro Air Vehicle (MAV) research. Extensive efforts are being done in this direction to replace gear and motor arrangement. In the present work, a mylar film with Polyvinylidene Fluoride or PVDF as actuator is demonstrated for the flapping in the frequency range of 3-16Hz. Specimens were prepared with different length and width ratios of mylar film. Uniaxially stretched and high quality poled PVDF films have been used for this application. Various parameters have been optimized to obtain maximum deflection of Mylar film by using PVDF as an actuator. The maximum displacement of flapping recorded was 5.78mm at 12Hz resonance frequency. Results have been validated using Ansys via modal & harmonic analysis.
