摘要
本文介绍了几种涡轮导向器排气面积检测方法,针对同一导向器采用不同检测方法检测,对检测结果进行对比,并对检测结果的不确定度进行分析。
Several throat area measurement methods of turbine nozzle were introduced. Different methods were adopted for measuring the throat area of the same turbine nozzle. The comparison was made between the different results and the uncertainty analysis of the results was carried out.
