摘　　要：等离子体是一种由大量电子、离子和中性粒子组成且总体上呈中性的物质聚集体,它不同于物质的气态、液态和固态,而被称为物质的第四态。等离子体在航空航天器隐身、降噪、推进及空气动力学等方面的应用一直是国外发达国家的重点研究领域之一。归纳总结了国外研究的主要等离子体风洞形式和等离子体发生器形式;探讨了低、跨、超声速风洞模型上等离子体的作用机理和产生的现象,介绍了在等离子体流动控制方面开展的风洞实验技术研究。Plasma,which is different from solid,liquid and gas, consists of a cloud of protons,neutrons and electrons. It is considered the fourth state of matter. The application research of plasma in aircraft stealth, noise controlling, propulsion and flow control is one of the main research area in developed countries. The main types of plasma wind tunnels and plasma generators are summarized. The phenomena and mechanism produced by plasma on low speed, transonic and supersonic wind tunnel models are discussed, and the wind tunnel experimental techniques on plasma flow control are presented.
