摘要
合理地设计当代跨声速风洞的稳定段、第二喉道、多喷嘴引射器、特殊的排气系统以及回流道等，对风洞获得低的噪声和低的湍流度、实现经济的增压运行、低的耗气量以及有效地控制和稳定试验段Ｍ数、降低风洞运转Ｍ数下限等都能起到显著的作用。
For contemporary transonic wind tunnels,the reasonable design of settling chamber,second throat,multi-nozzle injector,special exhaust and circuit ducts have great effects on achieving such good tunnel performance as low noise and turbulence level,economic pressurised operation, low gas consumption,effective controlling and stabilizing of test section Mach number,lower operation bottom boundary of Mach mumber,etc.
