Abstract: A turbine engine with an outer rotor that circumscribes an inner rotor or inner stator. The outer rotor includes circumferentially arranged components with a tip and a root. The root of each of the circumferentially arranged components can terminate at an inner platform, where the collection of inner platforms can define an inner band.
