摘　　要：随着超声速飞行器的迅猛发展,空气动力学者认为减小阻力是实现超声速飞行器飞得更快更远的目标和提高飞行器气动性能的一种重要手段。目前世界许多军事强国先后开展了超声速飞行器减阻技术的研究和探索。本文介绍了目前主要研究的主动减阻方法及原理,对逆向喷流、边界层控制及能量沉积减阻的研究现状进行了综述和分析,特别是对目前倍受关注能量沉积减阻技术进行重点综述。最后针对各类减阻技术的特点,分析了减阻方法所涉及的关键技术,为超声速飞行器减阻技术的发展提出了几点建议。With the rapid developing of supersonic vehicles, aerodynamicists believe that drag reduction is the most important means for improving the aerodynamic performance of vehicle. And if drag is reduced, the vehicles can fly faster and farther. Now in many military powers the drag reduction technology is studied and explored. The method and theory of active drag reduction are introduced in this paper. The research on reverse jet, boundary control and energy deposition are reviewed and analyzed. Especially the drag reduction technology of energy deposition is emphasized. Lastly, according to the characteristic of all kinds drag reduction, the involved key technologies are pmpesed. This paper can put forward some opinions for the developing of supersonic vehicle drag reduction.
