| Abstract: | 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. |
