    摘要: A turbofan assembly that includes a primary turbine section and an aft fan section positioned downstream from the primary turbine section. The primary turbine section includes a bypass duct configured to channel a stream of bypass air therethrough, and a main flow duct configured to discharge a stream of exhaust gas therefrom. The bypass duct and the main flow duct each include a discharge end positioned such that a mixed stream of bypass air and exhaust gas is discharged from the primary turbine section. The aft fan section includes at least one turbine and fan stage including a turbine portion and a fan portion coupled to the turbine portion. The turbine portion is positioned to receive the mixed stream of bypass air and exhaust gas, and the fan portion is positioned radially outward from the turbine portion.
