Labyrinth gas seals are commonly used for aeroengines and other machines.But failures,such as soundmachine coupling,vibration mode harmony and aeroelastic flutter,often occur.We analyzed the vibration character and aeroelastic stability of labyrinth gas seals which are used in a real aeroengine.According to the analysis result,we give some useful suggestions.
