Abstract (en)
A method of reducing dynamic imbalance in a bladed rotor assembly (7) by axially adjusting one or more of the blades (2) so as to redistribute mass along the geometric axis of the assembly. The blades may be axially adjusted to form a counterbalancing couple. Additional correction masses (6, 6a) may be added for supplemental correction of couple imbalance or residual static imbalance in the bladed rotor assembly. The invention offers a reduction in the weight penalty associated with conventional balancing corrections carried out on the bladed rotor assembly.
