摘　　要：对运输机控制增稳系统接通与断开状态下的阵风响应特性进行了仿真,研究了增稳控制律结构参数变化对飞机阵风响应特性的影响;在增稳控制的基础上,对引入副翼对称偏转进行阵风减缓的可行性进行了仿真与分析。结果表明,副翼对称偏转能够降低翼根弯矩,达到阵风减缓的目的。此方法可为运输类飞机的阵风减缓系统设计提供参考。The gust response simulation was performed for the transport when the control augmentation system was connected and disconnected, and the effect of the control law parameters to the transport gust response was studied. Based on the control augmentation, the gust load alleviation by using aileron was analyzed, and the results show that the aileron symmetrical deflection can reduce the bending moment of wing root, and this to alleviate the gust load. The method proposed in the paper can provide reference for design of gust alleviation system of transport aircraft.
