<p>A turbofan engine assembly (10) is provided. A turbofan engine assembly includes a core gas turbine engine (13) including a high-pressure compressor (14), a combustor (16) disposed downstream from the high-pressure compressor, and a high-pressure turbine (18) coupled to the high-pressure compressor using a shaft. A turbofan engine assembly (10) further includes counter-rotating booster compressor (22) coupled to the core gas turbine engine, the counter-rotating booster compressor includes a first rotor section configured to rotate in a first direction and a second rotor section configured to rotate in an opposite second direction. The turbofan engine assembly (10) further includes a single stage fan assembly (12) coupled to the first rotor section, a drive shaft (31) coupled between the low-pressure turbine (20) and the fan assembly. A turbofan engine assembly (10) further includes a gearbox (100) 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.</p> |
