Beschreibung
Zusammenfassung:	A method for engine assembly is provided, the method including forming an interdigitated rotor assembly comprising an inner rotor assembly rotatable at a first speed different from an outer rotor assembly rotatable at a second speed; fastening a gear assembly to the interdigitated rotor assembly to form an interdigitated turbine assembly; and coupling the interdigitated turbine assembly to a gas generator, wherein coupling the interdigitated turbine assembly to the gas generator includes coupling a planet carrier assembly of the gear assembly to a static frame of the gas generator.
