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。
Due to its small size, light weight, flexible use and low cost, the micro-aircraft is widely used in fields such as investigation, communication, search and rescue in civil and military fields. Among the many factors restricting the development of MAVs, gusts have a great impact on the stability and safe flight of MAVs. In the unsteady wind tunnel of Nanjing University of Aeronautics and Astronautics, a set of vertical gusts were developed and tested for vertical gust flow. A flexible wing micro-7 aircraft was designed and manufactured. Compared with the rigid wing, a vertical gust experiment of the micro-aircraft was carried out for the first time in China. The results show that the flexible wing can improve the stalling angle of attack of the MAV, has better longitudinal stability, and has certain vertical gust mitigation ability, which is beneficial to safe and stable flight.
