Abstract: This paper provides an overview on the research of the dynamics of complete aero-engine systems in recent years. The review includes the calculation of the dynamic characteristics of dual-rotor systems, dynamics analysis of rotor-roller bearing systems, research on the vibration of rotor blades, analysis of the dynamic responses of the casing, the rotor-dynamics in maneuver flight, dynamics analysis of the rubbing of rotor-casing systems, dynamics of the cracked rotor systems, etc. Finally, discussions are made to propose certain directions for future research.

Key words: dynamics of a complete aero engine system, dual rotor system, rotor roller bearing system, vibration of rotor blades, casing, maneuver flight, rubbing of rotor casing system, cracked rotor
