一种利用充气气囊替代机翼操纵面技术的探讨

The Investigation of a New Control Surface Technique with Gasbag

提出了一种运用充气气囊替代传统操纵面的方法,并采用数值模拟和风洞实验进行了研究,结果表明利用充气气囊改变机翼后缘附近的局部外形,能够像传统操纵面那样改变机翼气动力的特性。此技术方案消除了操纵面舵机和相应的传动系统,同时具有减小雷达反射面积的作用,为隐身飞行器提供操纵力矩探索了一条新的途径。

A new technique was investigated to substitute the conventional control surface with inflatable gasbag.Both numerical methods based on the unstructured grids and wind-tunnel experimental approachs were introduced to verify the effectiveness.It is shown that the local surface shape induced by the inflatable gasbag can result in the change of aerodynamic characteristics like the conventional control surface.This technique can eliminate the use of driving system for the conventional control surfaces,and the RCS of the wing will be reduced.The new technique is believed to supply a control system for modern stealthy flight vehicle.
