| 摘 要： | 固定翼微小型飞行器(MAV)飞行雷诺数低,属于低雷诺数空气动力学研究范畴.本文对不同尺寸的矩形翼、混合翼、梯形翼、齐默曼翼与反齐默曼翼平面布局MAV模型进行风洞测力试验.对比了各种平面布局气动特性,其中混合翼、反齐默曼翼和梯形翼较好地利用了前缘涡产生的涡升力,有良好的升力特性;展弦比较小的机翼表面脱体涡强度较大,改善了大迎角下的气动特性;大后掠角梯形翼有较好的过失速特性.

| Abstract: | The fixed-wing micro aircraft vehicles(MAV),which works under a low Reynolds number,have encountered certain kinds of aerodynamics problem.Different scales models of rectangular wings,mixed wings,trapezoid wings,Zimmerman wings and inversed Zimmerman wings were designed and force measuring experiment has been carried out in D6 wind tunnel in BUAA.Compared aerodynamics characters of those model,this paper points out that mixed wings,trapezoid wings and Zimmerman wings benefit from the leading edge vortex and... |
