MODULAR ROTOR BALANCING

A modular method of balancing a rotor assembly comprising two or more rotor sub-assemblies comprises dynamically balancing a set of rotor units each comprising one of the rotor sub-assemblies (52) and in which every other rotor sub-assembly is substituted by a respective simulator (54A, 56A). A resp...

Zusammenfassung:	A modular method of balancing a rotor assembly comprising two or more rotor sub-assemblies comprises dynamically balancing a set of rotor units each comprising one of the rotor sub-assemblies (52) and in which every other rotor sub-assembly is substituted by a respective simulator (54A, 56A). A respective set (55X, 55Y, 55Z) of balancing weights is applied to one or more of the rotor sub-assembly and simulators of a rotor unit (50A) to achieve dynamic balancing such that each set only corrects unbalance contributed by that rotor sub-assembly or simulator to which it is applied. Each set which is applied to a simulator is transferred to the corresponding sub-assembly. The sub-assemblies are then mated to form the balanced rotor assembly. Excitation of flexible modes of the balanced rotor assembly during its rotation is reduced or avoided.
