上世纪80年代中期.无人机(UAV)研发逐步升温。到90年代中期.无人作战飞机(UCAV)的研究又风起云涌,使无人机系统(UAS.含 UAV 和 UCAV)成为世界航空科技领域的热点之一。下面以站在发展前列的美国为例,谈谈UAS 发展中几个值得关注问题。对无人机系统的作战需求谈到对无人机系统的作战需求.可以先看看美国国防部发表的无人机路线图。欧洲国家的思路与之大同小异。美 The mid 80s of last century UAV R & D gradually warming up. By the mid-1990s, unmanned combat aircraft (UCAV) research surged again, making UAVs (including UAVs and UCAVs) one of the hottest topics in aeronautics and technology in the world. The following to stand in the forefront of the development of the United States, for example, to talk about the development of UAS several issues of concern. Demand for UAV Combat Requirements Speaking of the operational need for UAV systems, take a look at the UAV roadmap published by the U.S. Department of Defense. The ideas of European countries are similar. nice
