续航能力很大的无人驾驶中空飞行器在国际市场上销售状况 美国五角大楼最近生产了一批远程无人驾驶的中空飞行器,欧洲国家和中东国家关注着这些飞行器的军用和民用状况。 美国制造的远程无人驾驶的侦察飞机已经在顺利运作,最近又制造了第三架远程无人驾驶高空侦察机。第四架远程无人驾驶高空侦察机的生产也已签订了合同。这样一来,就为美国开辟了一个新的国际航空飞行器市场。 Marketability of Unmanned Aerial Vehicles with High Endurance in the International Market The Pentagon in the United States recently produced a number of long-range, unmanned aerial vehicles that are focused on the military and civilian uses of these aircraft in European and Middle Eastern countries. The U.S.-made long-range, unmanned reconnaissance aircraft have been operating smoothly and recently produced the third long-range unmanned aerial reconnaissance aircraft. The fourth long-range drone high-altitude reconnaissance aircraft production has also signed a contract. As a result, a new international aircraft market for the United States was opened up.
