摘要 微型飞行器由于飞行雷诺数比较低,其流动现象和机理比较复杂,对其进行相关的实验研究是尤其的必要且可行。本次试验通过由带有一定厚度和弯度的翼型构成的矩形机翼和反齐默曼机翼的对比实验、不同弯度的对比试验、不同参数的鸭翼实验以及翼尖小翼实验,重点分析了平面布局、弯度、鸭翼以及翼尖小翼对气动特性的影响。试验结果表明:在带有一定厚度和弯度的情况下反齐默曼气动性能好于矩形翼;适当的弯度能提高飞行器升力特性和纵向稳定性;鸭翼能有效地提高微型飞行器的气动特性;翼尖小翼能改善飞行器的升阻特性。 An experimental investigation focusing on the wingplan, esmher, canard and winglets has been conducted. Experimental result shows that the inverse Zimmenman wing has a relative better aerodynamics performance, result also appears that camber, canard and winglet can strongly affect the aerodynamics characteristics and the performance of MAVs.
