【摘要】 简要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.开展了方形截面导弹大攻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攻角的增加,方形截面导弹呈现不同的摇滚运动形态,包括静态稳定、准极限环摇滚、双周期摇滚、和等速滚转。更多还原

【Abstract】 The free to roll test technique in high speed wind tunnel is presented in this paper,including test apparatus and test methods as well as data acquisition remarkably.A test investigation of the dynamic behavior of an square section missile at high angles of incidence was conducted.Dynamic motions were obtained on a square section missile that was free to rotate about its longitudinal axis,different dynamic rolling motions were observed depending on the angle of incidence of the model sting.These dynamic regimes included damped oscillations,quasilimit -cycle rock motion,and chaotic oscillations.更多还原
