摘　　要：介绍了一种小型超音速风洞的基本结构和实验原理.设计了高速大数据量的数据采集系统.该系统的测试软件能满足实验测试过程中的实验参数自动测量与处理.以某实验模型为例,进行了空气动力实验参数测试,与某标准风洞实验结果对比证明,该实验方法和实验参数自动测试技术可应用于工程实践.Basic structure and experimental principles of a small supersonic wind tunnel are introduced. A data acquisi- tion system of high speed and large amount of data are de- signed. Test software could meet the requirements of auto- matic measurement and processing of experimental parame- ters during the experimental testing. In an experimental model as an example, the aerodynamic tests is carried out, this was compared with the results of a standard wind tunnel test. Experimental methods and experimental parameters that automated testing techniques can be applied to engineer- ing practice.
