无人驾驶飞机在第二次世界大战末期出现,首先运用于军事领域。在局部战争中,无人机进一步显示了它的长处,引起各国军事理论界的普遍重视。美、苏等国军队都视其为一种“前途无量的兵器”,投入大量人力物力发展研制。无人驾驶飞机有如下几个主要特点: 造价低,便于大量生产。一架现代歼击机的造价高达千余万美元,而无人机由于没有飞行人员所需的各种控制、指示和救生系统,其重量、体积大大压缩,造价只需几十万甚至数千美元。减少飞行人员,避免政治麻烦。据报道,北约国家训练一个飞行员需要用四至四年半时间,耗资50 The unmanned aircraft appeared at the end of World War II and was first used in the military field. In local wars, UAS further demonstrated its strengths and aroused the universal attention of military theoretical circles in various countries. The U.S., Soviet and other armies regard it as a “weapon of immeasurable future” and have invested a great deal of manpower and resources in the development and research. Drone has the following main features: low cost, easy mass production. A modern fighter plane costs as much as more than 10 million U.S. dollars. UAVs, due to the lack of various control, indication and life-saving systems needed by pilots, have been compressed in weight and volume to cost hundreds of thousands or even thousands of dollars. Reduce flight personnel and avoid political troubles. It has been reported that NATO training of a pilot takes four to four and a half years at a cost of 50
