摘　　要：减阻和降热是高速飞行器设计面临的2个核心问题。减阻可提高升阻比,减少飞行器燃料消耗;降热可减轻热防护系统重量,提升飞行器有效载荷。减阻降热是提高飞行器精细化设计,增强飞行器性能的关键技术。从高速飞行器减阻降热的工程需求出发,重点对激波、边界层的减阻降热流动控制技术的研究现状进行了回顾,并指出了其在工程应用中存在的问题与后续应重点关注的方向,以期实现飞行器主动流动控制的工程化应用,提升飞行器性能。Drag and heat reductions are two core issues in the design of high-speed flight vehicles.Drag reduction can enhance the lift-drag ratio of vehicles and decrease the fuel consumption,while heat reduction can reduce the weight of thermal protection system and promote the effective load of flight vehicles.Drag and heat reductions are the key technologies to improve the fine design and enhance the flight performance.This paper mainly reviews the re⁃search status of flow control technology for drag and heat reductions of shock wave and boundary layer,from the per⁃spective of the engineering requirements for drag and heat reductions of high-speed flight vehicles.This paper also points out the existing problems in engineering application and the direction that should be paid close attention to in the future,to realize the engineering application of active flow control of flight vehicles and improve the flight performance.
