Abstract:
A multi-spool gas turbine engine comprises a low pressure (LP) spool and a high pressure (HP) spool. The LP spool and the HP spool are independently rotatable about an axis. The LP pressure spool has an LP compressor and an LP turbine. The HP spool has an HP turbine and an HP compressor. The LP compressor is axially positioned between the HP compressor and an accessory gear box (AGB). The AGB is drivingly connected to the HP spool through the center of the LP compressor.
