In order to establish a method of evaluating unstable combustion states in advanced aeroengine and gas turbine combustion chamber engineering tests, a diagnosis method based on the multi-scale kurtosis index of the combustion chamber pressure pulsation signal was proposed, two unstable combustion states: combustion instabilities (CI) and flame instabilities (FI), were diagnosed, and the test and analysis were carried out in the gas fuel swirl combustor and liquid kerosene lean premixed pre-vaporized combustor. The results of the study showed that the normalized mean kurtosis index can be used as a CI status criterion, but it is not suitable for FI diagnosis; the CI and FI kurtosis indexes defined by the optimal time scale based on time scale independence can indicate the pressure oscillation level and the intermittent feature of pressure sequence, and the parameters have an increasing relationship with the CI and FI degree correspondingly; the established comprehensive judgment norm based on instantaneous pressure kurtosis and intermittent kurtosis can provide a criterion for online evaluation of combustion instability.
