Abstract: A gas turbine engine has a low pressure compressor, a first bearing system supporting an inner shaft, a second bearing system supporting an outer shaft, and a low pressure compressor hub mounted to the inner shaft. The low pressure compressor hub extends to the low pressure compressor between the first and second bearing systems and supports a plurality of stages of the low pressure compressor. Locating the low pressure hub between the bearings offers advantages to reduce deflection for a geared architecture.
