| 摘 要： | 设计研制了一种飞翼布局的柔性翼和刚性翼微型飞行器,并在风洞中研究了两种微型飞行器在定常风和水平阵风作用下的气动特性,给出了柔性翼和刚性翼微型飞行器气动特性的差别。研究结果表明:不论是在定常风情况下,还是在水平阵风环境下,柔性翼的气动特性要优于刚性翼结构,柔性翼具有延迟失速和缓和阵风影响的能力,有利于稳定飞行。PIV测量结果表明:由于柔性翼的变形使刚性翼和柔性翼翼面上的流态不同,从而使微型飞行器的气动特性发生改变。

| Abstract: | A flexible wing MAV and a rigid wing MAV are designed.In the unsteady wind tunnel in NUAA,the aerodynamic characteristics of these MAVs in steady wind and in horizontal gust are studied.The differences between the rigid and flexible wing are discussed.The results show that the aerodynamic characteristics of the flexible wing is better than that of rigid wing,not only in steady wind but also in horizontal gust.The flexible MAV has the ability of delaying stall and alleviating the effects of gust.This is bene... |
