| 摘要 |
A turbofan engine assembly includes a core gas turbine engine including a high-pressure compressor, a combustor disposed downstream from the high-pressure compressor, and a high-pressure turbine coupled to the high-pressure compressor using a shaft, counter-rotating booster compressor coupled to the core gas turbine engine, the counter-rotating booster compressor comprising a first rotor section configured to rotate in a first direction and a second rotor section configured to rotate in an opposite second direction, a single stage fan assembly coupled to the first rotor section, a drive shaft coupled between the low-pressure turbine and the fan assembly, and a gearbox coupled between the drive shaft and the second rotor section such that the low-pressure turbine drives the gearbox and such that the gearbox drives the second rotor section. A method of assembling the above turbofan engine assembly is also described herein.
