CH-3无人机航空物探磁放综合站应用系统设计与实现

Design and Implementation of Magnetic and RadioactiveAero-geophysical System Based on CH-3 UAV

为解决目前有人机航空物探所存在的作业效率低、成本费用高、危险性大以及缺乏灵活性等问题,本文提出了CH-3无人机航空物探磁放综合应用系统。研究设计了航磁水滴探头舱,并将其安装在磁场环境相对干净的翼尖,可以灵活地调节航磁探头使其保持与待测目的地磁场线垂直;研究设计了航放晶体箱,能够效减轻航放晶体在作业时的震动,并给航放晶体保温,防止其因温度变化过大而无法工作。借助于CH-3无人机本身续航时间长、挂载能力强、机动灵活等优势,同时搭载航磁设备及航放设备,使其具备超低空飞行、高精度地形跟随、夜航作业等能力。飞行试验表明,CH-3无人机航空物探磁放综合应用系统为我国区域地质调查增加了一种安全、高效、灵活、经济的航空物探勘查手段,具备了推广应用的基础。

An application system of CH-3 UAV aerogeophysical and magnetic amplifier integrated station is introduced.Maritime satellite communication equipment,aeromagnetic measurement equipment and aerial radiometric measurement equipment are added to the UAV flight platform.The antenna of the maritime satellite communication equipment is installed outside the skin of the UAV and is positioned directly above the payload cabin of the UAV flight platform;Maritime satellite is installed directly above the payload cabin of the UAV flight platform.The airborne equipment of satellite communication equipment is installed in the payload cabin.When the UAV flying platform is below 120 meters or the visual distance exceeds 200 km,the communication between the UAV flying platform and the ground station is realized by using the maritime satellite communication equipment.The aeromagnetic measuring equipment is installed in the payload cabin of the UAV flying platform and the UAV flying.The two ends of the wing of the platform are used to survey oil,gas and other minerals;the aerial radiometry equipment is installed in the load cabin to measure the content of radioactive elements in geological and mineral resources;and the bottom of the load cabin is made of non-metallic materials,which is directly in line with the aerial radiometry equipment.
