Rotor assembly, associated method of assembly, and computer program product therefor

A non-transitory computer program product containing computer-readable instructions, which, when operated on by a computer, performs the following method:

• determining a combination of relative circumferential positions of the individual rotor components associated to a bow shape configuration of the centers of mass along the axially-extending sequence based on geometrical reference values concerning individual rotor components each having a center of mass and configured to be assembled to one another in an axial sequence to form a rotor assembly, in which offsets of the centers of mass relative to a rotation axis of the assembled individual rotor components increase away from an end of the axially-extending sequence to a maximum offset of the offsets and decrease from the maximum offset toward an opposite end of the axially-extending sequence, the centers of mass being offset relative to the rotation axis in a same radial direction, the geometrical reference values being stored in a computer readable memory accessible to the computer.
