Abstract
A gas turbine engine includes a propulsor section including a propulsor having blades extending from a propulsor hub, and a propulsor shaft that drives the propulsor hub. A compressor section includes a first compressor having a rotatable compressor hub. A speed reduction device drives the compressor hub and the propulsor through a connection established axially forward of the epicyclic gear system relative to an engine longitudinal axis. The epicyclic gear system is straddled by forward and aft bearings that engage a carrier of the speed reduction device.
