展望未来3O年,到下一世纪20年代末、3O年代初,航空产品在信息技术、材料技术及生物技术等新技术革命的推动下,性能将会上一个新的台阶,产品质量将会发生质的飞跃.其标志是以第五代战斗机、高速民用运输机以及单或双级入轨的空天飞机等为代表的新一代航空器的出现.新的要求据分析,第五代战斗机将于2020年前后上天,该机种有超大迎角,能以M2.5的速度高速巡航,具有自适应智能结构、较高的损伤容限、良好的抗损性.并且能满足长寿命、高可靠性和高可维修性
Looking into the next 30 years, by the end of the 1920s and the early 1900s, aerospace products will have a new level of performance, driven by new technological revolutions such as information technology, materials technology, and biotechnology. Product quality will happen. A qualitative leap. Its mark is the emergence of a new generation of aircraft, represented by fifth-generation fighters, high-speed civilian transport aircraft, and single- and double-staged aerospace aircraft. New requirements According to analysis, the fifth-generation fighter aircraft will be held in 2020. The year before and after the day, the aircraft has a large angle of attack, can cruise at M2.5 speed, has an adaptive smart structure, high damage tolerance, good damage resistance, and can meet long life, high reliability High maintainability
