Abstract:

在高超声速下(6马赫)开展了双平面拍摄风洞自由飞试验,对非旋转钝锥在小攻角下的运动特性和圆锥摆动问题进行了研究.试验结果表明,虽然只预置了攻角而无侧滑角,模型仍然全部出现了圆锥摆动,且在观察窗范围内侧滑角幅值均大于攻角幅值.模型角运动虽均处于小于10°的小攻角和小侧滑角状态,但阻尼力矩项呈现较为明显的非线性,而静力矩项的非线性较弱,近似为线性.5组实验中,有1组模型的角运动可能趋于极限平面运动或者是攻角幅值较小的极限圆锥运动,另外4组试验模型角运动显示出了趋于极限圆锥运动的趋势.尾端盖对模型的角运动影响不明显,而尾部对称布置的片条状凸起物对整个角运动幅值变化的稳定性存在明显影响,有凸起物的两组模型角运动幅值波动明显较小.
