    Abstract
  • Experimental research on the axis locus of rotor and leakage characteristics of finger seal tests of clearance, transition and interference fit was conducted. The axis locus of rotor was measured by eddy current sensors. The results show that the higher the rotor rotation speed, the smaller the offset of the axis. And the offset does not affect the fit state if the wear is not considered, which assured the reliability of the test rig. And then the influences of factors such as the rotation speed, the pressure drop and the sealing clearance on the leakage characteristics was studied. The results show that the leakage coefficient slightly decreases with the increase of the rotation speed. For the case of clearance and transition fit, the leakage coefficient increases with the increase of the pressure drop which is below than 0.3MPa and then almost keeps constant while the pressure drop exceeds 0.3MPa. For the case of interference fit the pressure drop almost has no influence on leakage coefficient. The leakage coefficient reduces with the decrease of the sealing clearance and with the increase of interference.
