Design, Lift Prediction and Test of a PZT Drive Mechanism of a New Concept of Micro Flapping Wing Rotor

Abstract:

To reduce the complexity involved in achieving the intricate motion and hence complexity mechanism, a new concept of Micro Flapping wing Rotor is firstly proposed to achieve active flapping and passive rotary motion. Secondly, aerodynamic analysis is made to understand schematic principles of this MFWR. Thirdly, parametric study (flapping amplitude, flapping frequency and initial angle of attack) using Theodorsen’s theory for lift prediction makes a significantly role for aerodynamic characteristics. At last, the prototype of a piezoelectric drive mechanism is designed and tested to compare the experimental data with theoretical values. The comparison shows that the lift prediction is closer to the experimental results.
