美国国防部高速系统试验(HSST)项目技术进展研究

Study of the Technical Progress of the DOD High Speed System Test(HSST)Project

美国国防部高速系统试验(HSST)项目是迄今美国国防部唯一专门针对高速/高超声速试验科学技术开展的专项预研项目,对于高超声速试验基础设施建设及试验能力形成至关重要。本文简述了HSST项目的提出背景,总结了该项目的重点技术领域和重要技术进展情况。在该项目的支持下,美国已经掌握了一系列高超声速试验技术,研制成功了一些重要的高超声速试验设施,如高超声速气动热与推进清洁空气试验台(HAPCAT)、高空激光探测与测距大气传感系统(HALAS)、高保真度自动机载可重构跟踪系统(HAARTS)和“空中靶场”(SkyRange)等,这些能力为开展高超声速技术研究和型号研制奠定了坚实的基础。

High Speed System Test(HSST)project is the only pre-research project specially developed by the U.S.Department of Defense for high speed/hypersonic test science and technology,which is very important for hypersonic test infrastructure construction and test capability formation.This paper briefed the background of the High Speed Systems Test(HSST)project of the Department of Defense,summarized the focused technical areas and the development of the critical technologies.Through the execution of the HSST project,the US has grasped a series of hypersonic test technologies,and successfully developed some important hypersonic test facilities,such as Hypersonic Aero thermal and Propulsion Clean-Air Test bed(HAPCAT),High Altitude LiDAR Atmospheric Sensing(HALAS),High fidelity Automated Airborne Reconfigurable Tracking System(HAARTS)and Sky Range,etc,which laid a solid foundation for the hypersonic technology research and hypersonic weapon systems development.
