现代无人机大都是可以回收的。首先从经济性来看,无人机的价格相当昂贵,尤其是专用的高性能无人机。为了满足军用侦察、射靶和通信中继及民用农林调查、城市规划和大气海洋研究等需求,往往需要大量地使用无人机。如果所用的无人机是不可回收的,则由于每次使用必须消耗一架无人机而在经济上造成很大的损失。 Modern UAVs are mostly recyclable. First of all, from the economic point of view, UAV prices are quite expensive, especially for high-performance UAV. In order to meet the needs of military reconnaissance, shooting and communication relaying and civilian agroforestry, urban planning and atmospheric and oceanographic research, it is often necessary to make heavy use of UAVs. If the drone used is non-recoverable, it is economically very costly due to the need to consume one drone per use.
