Abstract:
1. A method of balancing a rotor, the method comprising the steps of: (i) supporting the rotor by means of a location feature of the rotor, the location feature being a surface for mounting the rotor and being provided at an interface of the rotor and a support; (ii) rotating the rotor about a test axis X; (iii) determining the characteristics of any dynamic unbalance of the rotor when rotated about the test axis; (iv) calculating the eccentric and/or angular offsets from the test axis required to eliminate the dynamic unbalance; and (v) modifying the location feature of the rotor so that, when the rotor is supported by means of the modified location feature, the rotational axis of the rotor is displaced from the test axis by the required eccentricity and/or angular offset.
