  • System and method for adjusting rotor-stator clearance
    Patent number: 8555477
    Abstract: A method and system for adjusting the clearance between a stator member and the tip of a rotor member in a rotor apparatus. The system comprises a position adjustment mechanism for adjusting the radial position of the stator member to any one of at least two and preferably three different radial positions. The system further comprises a variable pressure chamber having a first pressure state and a second pressure state. The system is arranged for applying a force for maintaining the stator member in either one of said at least two radial positions when said chamber is in said first pressure state and for allowing the position adjustment mechanism to adjust the radial position of the stator member between said at least two positions when the chamber is in said second pressure state.
