摘要
通过对某型涡扇发动机进气总压畸变流场动态总压紊流度的计算,得到了在改变采样频率以及设计不同的数字滤波器对动态总压紊流度计算的影响结果,为分析和处理动态数据提供了一种方法。
Based on the data of a turbofan engine inlet total pressure distortion experiment, the methods to predict inlet dynamic pressure turbulence were studied. The influence on the calculation results by some main factors, such as sampling frequency, digital filter cut-off frequency and the calculation modes were analyzed and compared. This brings a method to analyze and process dynamic data.
