摘要
利用航空发动机环行燃烧室噪声测试数据,采用时间序列自回归分析方法得到了燃烧室噪声及动压仿真模型ARMA(17,16),并用其对噪声时间历程数据进行了最佳预测。
In this paper,the simulation models ARMA(17,16) of combustion chamber noise and dynamical pressure were given by employing the time series Autoregression Moving Average Models in using the measured noise data of the annular combustion chamber of the aero - engine and the noise data of time history were also predicted by these models.
