In order to improve the angle precision of variable stator vane (VSV), the process and method of digital calibration for VSV were established. The main steps include: zero calibration of angular resolver, angle measurement of extreme position, length adjustment of connecting rod, angle checking of extreme position, vane’s angle and liner displacement of actuator, and angle checking of difference for all speeds. The platform system was also founded for VSV digital calibration. The method proposed avoided the impact from personal operation deviation and precision of calibration tool. The test results showed that, the new digital VSV calibration improved the angle precision at half degree. The improvement of angle precision promoted the matching performance of compressor and the accuracy of compressor performance evaluation.
