| 摘 要： | 由可移动插板式畸变发生器产生进气总压畸变流场,采用幅值域和频域分析的方法对畸变流场的脉动压力进行统计分析,得到了进气总压畸变流场中气流压力脉动的特征,以及其与稳态总压畸变图谱的关系。进一步认识了压力脉动的特性。

| Abstract: | The distorted flow field is generated by a distortion generator with a moveable sliding board in the experiment.Statistical analysis of pulsatile pressure is presented based on methods of amplitude domain,time domain and frequency domain.The characteristics of pulsatile pressure in inlet distorted flow field are obtained.And the relations of pulsatile pressure and steady total pressure distortion charts and maximum instantaneous pressure distortion charts are also researched. |
