在本文中，第一个广泛的研究结果的静态和移动平板翼的微型飞行器（MAVs）。在专门为低雷诺数研究设计的风洞环境中进行了风洞测力实验和粒子图像测速（PIV）实验。并进行了相应的数值模拟。本文讨论了机翼形状（椭圆形和矩形）、雷诺数（18，000、36，000和108，000）以及采用纯倾复运动和组合俯仰/倾复运动（折合频率k = 0.2）的不同运动形式的运动学的影响。
In the present paper, the first results of a broad study of static and moving flat plate wings for micro air vehicles (MAVs) are presented. Wind tunnel experiments with force measurements and particle image velocimetry (PIV) were performed in a specially designed wind tunnel environment for low Reynolds number investigations. Corresponding numerical flow simulations were also carried out. Effects of the wing shape (elliptical and rectangular), the Reynolds number (18,000, 36,000 and 108,000) and the kinematics using different motion forms of pure plunge and combined pitch/plunge with a reduced frequency of k = 0.2 are discussed.
