US 2026/0194010 A1 · GEARBOX ARRANGEMENT FOR DUAL SPOOL ENGINE ACCESSORIES

Abstract

A system includes a turbine engine, a low spool gearbox, and a high spool gearbox. The system also includes a first lubrication system configured to serve the low spool gearbox, and a second lubrication system, independent from the first lubrication system, configured to serve the high spool gearbox. The turbine engine includes a low-pressure spool and a high-pressure spool. The low spool gearbox is disposed within a core compartment of the turbine engine. The low spool gearbox is configured to transfer mechanical power between the low-pressure spool and a first accessory. The high spool gearbox is disposed within the core compartment of the turbine engine. The high spool gearbox is configured to transfer mechanical power between the high-pressure spool and a second accessory.
