前后双扑翼微型飞行器推力研究

Thrust Research for Dual Flapping-Wing Micro Air Vehicle

为探讨前后双扑翼微型飞行器产生推力的机理和变化规律,通过在动态网格上求解Navier-Stokes方程,对前后双扑翼在不同水平距离、相位角、扑动频率和来流攻角下推力的变化进行了数值模拟和分析。总结出推力随各参数变化的规律,为前后双扑翼微型飞行器的设计提供了参考依据。

A new dual flapping-wing model of micro air vehicle （MAV） is developed to explore mechanism of thrust generation in dual flapping-wing MAV. The unsteady viscous flow fields around dual flapping airfoils in tandem configurations are simulated by a Navier-Stokes solver using dynamic deformable hybrid meshes. The thrust variation of dual flapping airfoils under conditions of different flap parameters, such as horizontal distance, phase angle, flapping frequency, angle of attack, and so on is simulated and analyzed. The variation law of the thrusts is concluded. The research provides a reference for designing dual flapping-wing MAV.
