PROBLEM TO BE SOLVED: To provide a turbofan engine with a counter-rotating fan without posing such a problem as weight increase caused by a counter-rotating low-pressure turbine. SOLUTION: The turbine engine assembly includes a core gas turbine engine 12 including a high-pressure compressor 18, a combustor 20, and a high-pressure turbine 22. The turbine engine assembly further includes a booster compressor 30 coupled upstream from the core gas turbine engine. The turbine engine assembly further includes an intermediate-pressure turbine 32 coupled to the booster compressor, the intermediate-pressure turbine disposed downstream from the core gas turbine engine. The turbine engine assembly further includes a counter-rotating fan assembly disposed upstream from the booster compressor, the counter-rotating fan assembly includes a first fan assembly configured to rotate in a first direction and a second fan assembly configured to rotate in an opposite second direction. The turbine engine assembly further includes a low-pressure turbine 14 disposed downstream from the intermediate-pressure turbine, the low-pressure turbine configured to drive the counter-rotating fan assembly.
