Abstract

Flexible wing aircraft with the function of active deformation can improve the aerodynamic characteristics by the adaptive deformation of the airfoil, to maintain its own flight stability. In this paper, the active deformation of the flexible wing is realized by the piezoelectric material actuator, instead of the traditional servo control surface. This driving method can solve the issues about the continuous deformation of the airfoil and the timeliness of response well. The mechanical model of the piezoelectric composite flexible wing and the static aeroelasticity model of each wing panel are built in this paper. Based on the models, the coupling relationship among the piezoelectric force, the aerodynamic lift and the airfoil torsional deformation is obtained. According to the simulation results of the aerodynamic iteration optimization program AeroBeamSaw, the effect of the size and location of the active deformation on the aerodynamic lift is researched.
