2.4m跨声速风洞槽壁试验段调试及流场校测

摘要

This paper describes the test and flow field calibration of the new developed slotted test section for 2.4m transonic wind tunnel.Calibration data indicate that the boundary layer thickness and wave minimization performance satisfy the use requirement,and core uniformity has met the requirements of the National and Military Standard in M =0.30～1.00,and approached the advanced standard for lower Mach number.The slotted test section is capable of operating client tests,and will play an important role in national large plane aerodynamic design process.%介绍了新研制的2.4m跨声速风洞槽壁试验段调试情况及流场校测结果.结果表明:该试验段边界层厚度、消波特性等满足使用需求,具有较大的流场均匀区,在M数为0.30～1.00范围内的核心流场M数分布均方根偏差满足GJB1179-91高速风洞与低速风洞流场品质规范合格指标要求,部分马赫数的均方根偏差达到或接近先进指标要求,可投入型号试验.槽壁试验段的成功研制提高了2.4m跨声速风洞承担大型飞机试验任务的能力,在中国大型飞机工程气动设计中将发挥重要的平台作用.
