| Abstract: | The fitted models of the total sound level, main peak value and its frequency by employing the liner and nonlinear r egression methods in using the noise data measured inside and outside the annula r combustion chamber of the aircraft engine were given in this paper. The noise data provided by this approach can be used as the reference in studying the stru ctural integrity and reliability of the combustion chamber. |
