A turbofan gas turbine engine (10) includes a first shaft (20) for mounting and rotation of a fan (14), the first shaft including a single stage internal gear (24) mounted on the first shaft aft of the fan. The turbofan engine further includes a second shaft (40) for mounting and rotation of a low pressure compressor and a low pressure turbine, the second shaft including a pinion gear (44) mounted thereon forward of the low pressure compressor. The pinion gear meshes with the single stage internal gear to drive the first shaft and fan. The second shaft is parallel and off-set from the first shaft. |
