Both theoretical and experimental analyses are performed to investigate the limit cycle flutter bifurcation of a sweepback wing with an external store in the tip of the wing.
从理论及实验两方面,研究了带外挂后掠机翼的极限环颤振分叉现象,得到了稳定、半稳定及不稳定极限环。
Moreover, for a fixed speed, the upper and lower amplitudes of the wing-store system with uncertainty are obtained and the influence of the uncertainty is cognized on the limit cycle phase pictures.
进而可以得到一定来流速度下,具有不确定机翼外挂系统幅值的上下界,以及不确定参数对极限环相图的影响。
