The invention discloses a fixed-wing unmanned aerial vehicle forced landing method and system, and the method comprises the steps: obtaining the current air speed of a fixed-wing unmanned aerial vehicle when the fixed-wing unmanned aerial vehicle enters a forced landing program; controlling the fixed-wing unmanned aerial vehicle to be adjusted from the current airspeed to the gliding flight airspeed; acquiring ground terrain information corresponding to the current airspace of the fixed-wing unmanned aerial vehicle; selecting a forced landing area according to the ground terrain information to execute a forced landing gliding task; in the process of executing the forced landing gliding task, collecting region area information, region ground humidity and softness information and region terrain trend information of a forced landing region; generating a landing grounding scheme of the fixed-wing unmanned aerial vehicle according to the regional area information, the regional ground humidity and softness information and the regional terrain trend information; and when the forced landing glide task process is finished, controlling the fixed-wing unmanned aerial vehicle to land and ground according to the landing grounding scheme. The safety of the fixed-wing unmanned aerial vehicle during forced landing in the forced landing area is improved, and the damage rate of the fixed-wing unmanned aerial vehicle during forced landing is reduced.

    本申请公开了一种固定翼无人机的迫降方法及系统,其方法包括:当固定翼无人机进入迫降程序时,获取固定翼无人机的当前空速;控制固定翼无人机从当前空速调整至滑翔飞行空速;获取固定翼无人机当前空域对应的地面地形信息;根据地面地形信息选择迫降区域执行迫降下滑任务;执行迫降下滑任务过程中,采集迫降区域的区域面积信息、区域地面湿软度信息及区域地势走向信息;根据区域面积信息、区域地面湿软度信息及区域地势走向信息,生成固定翼无人机的着陆接地方案;当迫降下滑任务过程结束时,根据着陆接地方案,控制固定翼无人机进行着陆接地。本申请提高了固定翼无人机在迫降区域进行迫降着陆时的安全性,降低固定翼无人机在迫降时的损毁率。
