摘　　要：微型飞行器是航空领域一个新的研究热点,涉及多个技术研究领域。围绕与微型飞行器相关的低雷诺数空气动力学问题,进行了绕圆柱体低雷诺数非定常流动的数值模拟方法研究、低雷诺数机翼粘性非定常流动机理研究、扑翼的气动力估算方法研究、微流动控制的数值模拟研究和微型飞机的气动实验研究,指出了微型飞行器面临的问题,并展望了其发展趋势。Micro air vehicles(MAV)has become a new research focus in the aviation field, involving many technologies. In the paper, some research results are presented, such as unsteady viscous fluid numerical simulation method of the cylinder and unsteady fluid mechanism of wing at low Reynolds number, estimate method of aerodynamic force of the flapping wing, numerical simulation method of micro-fluid control principle and MAV wind tunnel experiment, etc. Some problems that MAV faced with are also given, and development trend of the MAV is discussed.
