| Abstract: | The fourth and the sixth stage blades of a kind of aero engine compressor are taken as examples, the relationship between vibration frequency of blade measured (or calculated) on ground and real one in air is studied. By the relation, the vibration frequency measured (or calculated) on the ground can be transformed into corresponding one in air. So the theoretic basis for restraining blade fault and improving blade reliability is founded. |

| Keywords: | Compressor blade Vibration frequency Measured frequency Transformed frequency |
