Abstract
A rotor module, including: a blade cluster of a plurality of blades secured to a rotor disk of the rotor module; and counter weights secured to the rotor disk, wherein the counter weights cause a center of gravity of the plurality of blades to be zeroed out with respect to an axis 'O' of the rotor disk and wherein the counter weights cause a moment of inertia Jx about an X axis of the rotor disk is equal to a moment of inertia Jy about a Y axis of the rotor disk when the rotor module is rotated about the axis “O”.
