| The aim of research was to detect the misfire of individual cylinders of the Rotax 912 ULS aircraft engine based on engine vibration signals. Vibrations were recorded in three direction, and their time series subject to linear frequency analysis and non-linear recurrence analysis. The greatest vibration difference between a fully operational engine and the engine with one piston off was observed along the piston movement axis (Y-axis). With one cylinder off, the dynamic response of the engine changed in both linear and non-linear manner. Based on the spectral value of the power amplitude of two selected frequencies, a linear indicator describing the vibration level was developed. The values of non-linear indicators were calculated on the basis of the periodicity of the engine operation. Both methods proved capable of qualitatively detecting the fact of misfires in various cylinder configurations. Used in combination, they enable user to identify the defective cylinder. |
