This work is devoted to the development a new multilevel vibration control system of aviation gas-turbine engines (GTE). The bases of the new system are: existing aboard vibration control system for current control and awareness about actual levels of vibration at the harmonics of the rotor rotation (main level); complementary dedicated microcontroller for analysis of “normal vibration” in order to predict or detect small damages of engine systems and details (auxiliary level); signal processing methods for damages diagnosis and decision making about GTE condition. The efficiency of the proposed system and using the signal processing methods is demonstrated by the results of computer simulation of the processes of receiving the information about the GTE vibrating condition, transformation and analysis of it at the main and auxiliary levels.
