Abstract
Method of assembling a rotor assembly of a gas turbine engine having a plurality of components. The method comprises in one aspect calculating the bending forces due to the mass distribution along the rotor. In another aspect, an optimization routine iterates different rotor arrangements, comparing the calculated bending moments to determine a set of component positions that minimizes the bending forces. In another aspect, mass corrections are optimized to balance the rotor assembly.
