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 method of using inflatable airbag to replace the traditional control surface is proposed. The numerical simulation and wind tunnel experiment are carried out. The results show that the use of inflatable airbag to change the local profile around the trailing edge of the wing can change the wing like the traditional control surface Pneumatic properties. This technical solution eliminates the steering gear and the corresponding transmission system of the control surface, and at the same time has the function of reducing the radar reflection area and exploring a new way for providing steering torque to the stealthy aircraft.
