| 摘 要： | 气流在叶片机中的实际流动过程极其复杂 ,必须利用各种测试手段来了解叶片机级间三元流场。本文介绍一种小球型五孔探针测量系统用于压气机级间参数测量的结果。该系统具有一些突出的特点。其一是探针头部尺寸小 ,对气流的干扰小 ;其二是数据处理手段先进 ,探针校准程序及测量结果的处理程序比较成熟。实践证明 ,其测试结果与常规探针所测得的结果非常接近 ,重复性较好。由测量结果整理出的压气机性能参数与设计值也比较接近。一、五孔探针的校准及其使用 由于球头和感压孔 (见图 1 )的加工误差 ,同一批制造的同类型五孔探针其气动特性也…

| Abstract: | A small five hole spherical pressure probe instrumentation system is developed and applied to compressor interstage parameter measurement.This instrumentation system has two features:One is smallness of flow disturbance due to small dimensions of the probe head,the other is an advanced data processing method of this system which comprises perfect probe calibration and data processing procedure.The analysis of the test results demonstrates that its performance is stable,its accuracy and data repeatability of its measurements are quite well.This instrumentation system can be applied to verification of the design parameters. |
