方形截面导弹动态摇滚特性研究

介绍了高速风洞自由摇滚实验技术的实验装置、实验方法、数据采集等。开展了方型截面导弹大迎角下的摇滚特性研究，给出了典型的结果，研究结果表明随着模型迎角的增加，方形截面导弹呈现不同的滚转运动形态，包括静态稳定、准极限环摇滚、双周期震荡和等速滚转。最后对摇滚的机理进行了探讨与分析。

Dynamic behavior of square section missile in roll at high incidence

The free to roll test technique including test apparatus and test methods as well as data acquisition in high speed wind tunnel is presented in this paper. An investigation of the dynamic behaviors of a square section missile at high angles of attack was conducted. Dynamic motions were obtained on a square section missile that was free to rotate about its longitudinal axis at different angle of attack. Different dynamic rolling motions including damped oscillations, quasi-limit-cycle rock motion, and chaotic oscillations were observed. The mechanism of rock motions are explored too.
