一种便携式固定翼山地监察无人机研究

Research on a Portable Fixed-wing Mountain Surveillance UAV

针对固定翼型监察无人机在山地等复杂环境不便于携带、起降使用的问题,研究了利用“北斗定位系统”定位功能和可拆卸、手抛无人机为核心的便携式固定翼山地监察无人机。该无人机采用手抛式起飞,感应卡锁解体结构,无人机可以安全降落。制作了实物样机,试验测试结果表明:无人机尺寸为1200 mm×800 mm×150 mm,起飞高度为2500 mm,起飞仰角为45°,推力为30 N,无人机可续航1 h,低速下降触地2 s可完成解体降落。该研究可帮助固定翼无人机摆脱地形依赖,实现固定翼无人机全地形的使用,具有一定参考价值。

Aiming at the problem that fixed-wing surveillance UAVs are not easy to carry,take off and land in complex environments such as mountains,a portable fixed-wing surveillance UAV for mountains with the positioning function of Beidou positioning system and detachable and hand-dropped UAV as the core are studied.The unmanned aerial vehicle(UAV)takes off by hand throwing,the induction lock disintegrates the structure,and the UAV can land safely.A actual prototype is made,and the test results show that the size of the UAV is 1200 mm×800 mm×500 mm,the takeoff height is 2500 mm,the takeoff elevation angle is 45°,and the thrust is 30 N.The UAV can last 1 h,and the disintegration and landing can be completed when the UAV drops for 2 s at low speed.This study has certain reference value for fixed-wing UAVs to get rid of terrain dependence and realize the use of fixed-wing UAVs on all terrain.
