Abstract
A system includes a turbine engine, a low spool gearbox, a high spool gearbox, and an interlink mechanically coupling the low spool gearbox to 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.
Claims20
A system comprising:
- a turbine engine including an engine core casing, a low-pressure spool and a high-pressure spool;
- a low spool gearbox disposed within a core compartment of the turbine engine, the low spool gearbox configured to transfer mechanical power between the low-pressure spool and a first accessory, and mechanically coupled to the engine core casing via at least a first thrust link;
- a high spool gearbox disposed within the core compartment of the turbine engine, the high spool gearbox configured to transfer mechanical power between the high-pressure spool and a second accessory, and mechanically coupled to the engine core casing via at least a second thrust link;
- and
- an interlink mechanically coupling the low spool gearbox to the high spool gearbox.
An apparatus comprising:
- a low spool gearbox configured to be disposed within a core compartment of a turbine engine, the low spool gearbox configured to transfer mechanical power between a low-pressure spool of the turbine engine and an accessory,
- wherein the low spool gearbox is configured to be mechanically coupled to a high spool gearbox via an interlink, and
- wherein the low spool gearbox is configured to be mechanically coupled to an engine core casing of the turbine engine via a rocker link.
An apparatus comprising:
- a high spool gearbox configured to be disposed within a core compartment of a turbine engine, the high spool gearbox configured to transfer mechanical power between a high-pressure spool of the turbine engine and an accessory,
- wherein the high spool gearbox is configured to be mechanically coupled to a low spool gearbox via an interlink, and
- wherein the high spool gearbox is configured to be mechanically coupled to an engine core casing of the turbine engine via a rocker link.
