Investigation on aerodynamic characteristics of flexible wing with different flexibilities

Wenxin Niu

Abstract

In order to study aerodynamic characteristics and wind-resistance performance of the flexible wing with different flexibilities,nine flexible wing micro air vehicles(MAV) with different flexibilities were produced,and wind tunnel test was performed in special micro air vehicle wind tunnel of Northwestern Polytechnical University(NPU).The influence of wind velocity and angle of attack on aerodynamic characteristics was investigated and the aerodynamic characteristics of a good flexibility of the flexible wing MAV were optimized.The results of experiment can guide us in conceptual design and aerodynamic design of flexible wing MAV.
