摘要: 为了有效地开展对超、跨音速压气机的研究,我们自行设计、制造和调试成功了超、跨音速叶栅风洞。 一、风洞概况及特点 1.风洞概况 本风洞为吹气式暂冲风洞（图1）,全长19m,中心高1.2m。风洞最大工作流量为22kg/s,稳定工作时间大于4分钟。Abstract: SB301 wind tunnel was designed to test two-dimensional cascades of compres- sor in subsonic,transonic and supersonic flow. The wind tunnel has been equipped with advanced instrumentation and enables to accomplish a wide range of experimentation. It is first successful one for testing the two-dimensional cascades of compressor in transonic and supersonic flow in China by now. It provides a new test rig for research and development of aeroengines with high performances.
