摘要
Fluid-structure coupled method has been applied to research the aeroelastic stability of compressor blades, and the effects of high-low altitude on blade flutter characteristics are investigated through comparison. Results show that, these frequencies corresponding to displacement, elastic strain of blade are identical with the first order natural frequency based on frequency spectrum analysis, which means that there remains a strong possibility on the frequency in the event of blade flutter. The amplitude of displacement, elastic strain on the ground is greater than that in high altitude, so aeroelastic stability on the ground is lower than that in high altitude.
