摘要
西北工业大学ＮＦ－３风洞的气动设计、结构设计和测控系统都有其特点，流场校测和标模实验的结果表明，该风洞在最大风速、能量比、紊流度等重要性能指标上都达到国际先进指标。
The aerodynamic design. construction design and control system of the NF-3 wind tunnel of North-wester Polytechnical University all have many features.Results of the stream field calibration and typical model testing indicate that tEe maximum wind velocity, energy ratio and turbulence etc., which present main features of a wind tunnel,all achieve national advanced indices.
