COUNTERROTATING TURBOFAN ENGINE |
摘要 |
A turbofan engine (10) includes a fan (14), compressor (18), combustor (20), high pressure turbine (22), and low pressure turbine (24) joined in serial flow communication. The high pressure turbine (22) includes two stages of rotor blades (46) to effect corresponding exit swirl in the combustion gases discharged therefrom. A transition duct (50) includes fairings extending between platforms (54,56) for channeli ng the combustion gases to the low pressure turbine (24) with corresponding swirl. First stage rotor blades (66) in the low pressure turbine (24) are oriented oppositely t o the rotor blades (46) in the high pressure turbine (22) for counterrotation. |
