摘? 要: 為解決目前有人機航空物探所存在的作業效率低、成本費用高、危險性大以及缺乏靈活性等問題,本文提出了CH-3無人機航空物探磁放綜合應用系統。研究設計了航磁水滴探頭艙,并將其安裝在磁場環境相對干凈的翼尖,可以靈活地調節航磁探頭使其保持與待測目的地磁場線垂直;研究設計了航放晶體箱,能夠效減輕航放晶體在作業時的震動,并給航放晶體保溫,防止其因溫度變化過大而無法工作。借助于CH-3無人機本身續航時間長、掛載能力強、機動靈活等優勢,同時搭載航磁設備及航放設備,使其具備超低空飛行、高精度地形跟隨、夜航作業等能力。飛行試驗表明,CH-3無人機航空物探磁放綜合應用系統為我國區域地質調查增加了一種安全、高效、靈活、經濟的航空物探勘查手段,具備了推廣應用的基礎。

【Abstract】: 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.

目前航空物探以有人機為主要載體,然而近年來隨著航空物探作業量的增加,航空物探作業飛機出現事故的概率也在增加;有人機對起降條件、地勤支持等要求很高,且無法在夜間和惡劣天氣條件下開展航空物探作業,目前航空物探項目總經費超過65%用于租賃有人機,顯而易見,危險性高、成本極高、靈活性差以及作業效率低等問題已經嚴重制約了航空物探的技術發展和大規模推廣應用。……
