The invention discloses an anti-gust device suitable for a fixed wing structure. The device can be applied to miniature and small aircrafts; and flight stability and safety in a gust environment are improved. The device comprises an attack angle active control section, a rigid middle section and a gust passive control section. An active control portion is located on a front edge of a wing, and according to the gust angle monitored in real time, a front edge driven by a piezoelectric composite material can be controlled to lower a head, an actual attack angle is reduced, and stall is avoided; and a passive control portion is located on a rear edge of the wing and is made of tough resin, tiny vibration is generated during flying, an aerodynamic force sudden change is relieved before the wingstalls, a head-up action amplitude caused by a pitching moment peak fluctuation is reduced, and a possibility of sudden stall is reduced. An active control mode and a passive control mode are combined so that the device not only has flexible and changeable functions, but also has stable and reliable effects, and has a good anti-gust effect; and meanwhile, due to adoption of a wing multi-section structure, a technical threshold and a manufacturing price are reduced while performance is met.

    本发明公开了一种适用于固定翼结构的抗突风装置,可应用在微型和小型飞行器,提高突风环境下的飞行稳定性和安全性,该装置包括迎角主动控制段、刚性中段和突风被动控制段,主动控制部分位于机翼前缘,可根据实时监测到的突风角度,控制由压电复合材料驱动的前缘低头,降低实际迎角,避免失速发生;被动控制部分位于机翼后缘,由韧性树脂构成,飞行时产生微小振动使得机翼失速前减缓气动力突变,降低俯仰力矩峰值波动引起的抬头动作幅值,降低突然发生失速的可能性。主动与被动控制方式的结合使得该装置既有灵活多变的功能,又有稳定可靠的效果,具有良好的抗突风作用;同时机翼多段结构的采用在满足性能的同时降低了技术门槛和制造价格。
