The invention provides a working method of a tandem dual-rotor unmanned helicopter safety guarantee device. The tandem dual-rotor unmanned helicopter safety guarantee device comprises a rotor tilting device, a flight state detector and a landing buffer device, and the rotor tilting device comprises a universal transmission shaft connected with the rotor rotating shaft and the output shaft of the engine, a tilting guide rail fixed on the main structure of the aircraft body, and a tilting moving module arranged on the tilting guide rail and used for driving the rotor rotating shaft to tilt. The flight state detector comprises a gradienter installed in the aircraft body, a laser rotor rotating speed measuring instrument installed in the aircraft body below the rotor, an airspeed tube installed on the aircraft body and a signal integration system. The landing buffer devices are installed at the two ends of the machine body. Through the arrangement of the single-side rotor tilting mechanism, when the single-side rotor loses lift force, the lift force direction of the rotor on the other side can be adjusted, so that the lift force and gravity are on the same straight line, and the phenomenon that rollover is out of control is prevented.

    本发明提供了一种纵列式双旋翼无人直升机安全保障装置的工作方法,该装置:包括旋翼倾转装置,飞行状态检测器,落地缓冲装置;所述的旋翼倾转装置包括与旋翼旋转轴和发动机输出轴相连的万向传动轴,与固定在机体主结构上的倾转导轨,以及在倾转导轨上带动旋翼旋转轴发生倾转的倾转移动模块。所述的飞行状态检测器包括安装在机体中的水平仪,安装在旋翼下方机体中的激光旋翼转速测量仪,安装在机体上的空速管以及信号集成系统。所述的落地缓冲装置安装在机体的两端。本发明通过设置的单侧旋翼倾转机构,可以在单侧旋翼失去升力时,调整另一侧旋翼的升力方向,使得升力与重力在一条直线上,防止出现侧翻失控。
