N自古作战讲求兵贵神速,现代战争已经证明大型军用运输机(本文简称“大运”)具有其他载具都难以比拟的重要作用。研究者认为,军事空运能力在一定程度上已成为作战胜败的决定性因素,运输飞机的装备数量、性能水平和作战效能是衡量一个国家国防实力的重要标志,因此各军事大国都高度重视空运部队的建设。以“攻防兼备”为发展目标的人民空军更是迫切需要大型运输机!然而,今中国航空人无法回避的尴尬现状是——迄今还没有一架国产大飞机服役,国家不得不花费巨资购买数量有限、性能落后的国外产品。 Since ancient times, the warfare has been striving to increase the number of soldiers and soldiers. The modern warfare has proved that the large military transport aircraft (hereinafter referred to as the “Dayun”) has an important role that other vehicles can hardly match. Researchers believe that the capability of military air transport has to a certain extent become the decisive factor in the success or failure of the battle. The quantity, performance level and operational effectiveness of the transport aircraft are an important indicator of the national defense strength of a country. Therefore, all military powers attach great importance to air transport units Construction. However, the awkward situation that China’s aviation people can not avoid now is that no domestic big aircraft has so far served and the country has to spend huge sums of money Buy a limited number of foreign products with poor performance.
