    摘要: A gas turbine engine (10) comprises a fan drive gear system (12), a low spool (14) connected to the fan drive gear system, and a high spool (16) disposed aft of the low spool. The low spool comprises a rearward-flow low pressure compressor (26) disposed aft of the fan drive gear system, and a forward-flow low pressure turbine (30) disposed aft of the low pressure compressor. The high spool comprises a forward-flow high pressure turbine (32) disposed aft of the low pressure turbine, a combustor (18) disposed aft of the high pressure turbine, and a forward-flow high pressure compressor (36) disposed aft of the combustor.

    摘要: A gas turbine engine (10) includes a high spool (14), a low spool (12) mechanically connected to a fan (26, 28), a gear system (24), an actuator (22; 22'), and a starter (50). The gear system is actuable to engage and disengage the low spool to and from the high spool. The actuator is connected to the gear system for selectively engaging and disengaging the gear system. The starter is connected to the low spool and can drive rotation of the high spool through the low spool when the gear system is engaged.
