The aim of the invention is to compensate for the position-dependent length changes caused by the effect of weight in a variety of closed kinematic chains, for connecting a stationary first element to a movable second element. The airfoil further includes: first and second sidewalls joined together at a leading edge and a trailing edge, where the first and second sidewalls extend from a root disposed adjacent the dovetail to a tip plate for channeling combustion gases thereover; and, at least one tip rib extending outwardly from the tip plate between the leading and trailing edges. The short stroke stage can be magnetically levitated from the long stroke stage. A core loaded with the modified bundle design may be simulated to generate bundle performance outputs.
