柔性翼微型飞行器垂直阵风响应特性的实验研究

微型飞行器因其体积小、重量轻、使用灵活、成本低,广泛应用于军民领域的侦查、通讯、搜救等领域。在制约微型飞行器发展的诸多因素中,阵风对微型飞行器的稳定、安全飞行影响很大。在南京航空航天大学非定常风洞内,研制了一套垂直阵风装置,进行了垂直阵风的流场测试。设计制作了一种柔性翼微7型飞行器,并制作了刚性翼与其对比,在国内首次进行了微型飞行器垂直阵风实验。结果表明：柔性翼能够提高微型飞行器的失速迎角,且具有更好的纵向稳定性,有一定的垂直阵风缓和能力,有利于安全、稳定飞行。

Experimental investigation on the vertical gust response characteristics of the MAV with flexible structure

Micro aerial vehicle （MAV） is a new type of aircraft, which has traits of mini volume, light weight, higher flexibility, low cost, etc. So MAV could be extensively applied to military and civil fields, including reconnaissance, communication, and rescue. Concerned with several obstacles of restricting the MAV development, the gust is the most important factor that af fects the MAV to flight safely and steadily. The equipment for generating vertical gust is developed and an angle surveying method which could be applied on the vertical gust flow field is stud- led. Then a rigid wing MAV and a flexible wing MAV of a flying wing configuration are designed and fabricated. The vertical gust experiment for MAV is carried out in unsteady wind tunnel of NUAA. The results show that the flexible wing can increase the stall angle of attack. At the same time, it has better longitudinal stability. The flexible wing has the ability of alleviating the effects of vertical gust which benefits to safe and steady flight.
