国外高超声速飞机发展分析

Analysis on the Development of Hypersonic Aircraft Abroad

高超声速飞机突破现有飞机的速度与高度包线,具有可重复使用、宽速域飞行的技术优势,是未来飞行器技术发展的重大方向之一。国外正加快高超声速导弹向飞机平台的技术转化,已设立多个高超声速飞机研究项目,研究进展较快。本文总结了国外高超声速飞机的研发历程与研究项目整体情况,梳理了在研重点型号的概念方案和研究进展,分析了国外高超声速飞机的主要发展趋势。研究认为,面对国外高超声速飞机加速研制的态势,我国应加强对动力等关键技术的攻关,提高试验能力,为高超领域的科技竞争奠定基础。

Hypersonic aircraft breaks through the speed and altitude envelope of existing aircraft,and has the technical advantages of reusable and wide-speed flight,which is one of the major directions of aircraft technology development in the future.Foreign countries are accelerating the technological transformation from hypersonic missiles to aircraft platforms,and several hypersonic aircraft research projects have been set up,which have made rapid progress.This paper summarizes development history and the overall situation of research projects of hypersonic aircraft abroad,combs the conceptual schemes and development progress of key models under research,and analyzes the main development trends and target images of hypersonic aircraft abroad.It is considered that in the face of the situation of accelerating the development of hypersonic aircraft abroad,we should press ahead,strengthen the research on key technologies such as engine,systematically arrange and improve the test ability,and lay the foundation for scientific and technological competition in the hypersonic field.
