DUAL ACCESSORY GEARBOX
First Claim
1. A gas turbine engine, the gas turbine engine comprising:
- an engine shaft rotatable with at least one of a fan section, a compressor section, or a turbine section; and
an accessory gearbox assembly comprising a towershaft, a first gearbox, a torque transfer assembly, and a second gearbox, wherein the towershaft is rotatable with the engine shaft and extended therefrom and mechanically coupled to the first gearbox, and wherein the first gearbox transmits mechanical energy from the engine shaft via a first shaft defining a first end and a second end, wherein the first shaft extends at the first end from the first gearbox and through the torque transfer assembly and coupled thereto, and wherein the first shaft extends from the torque transfer assembly to the second gearbox at the second end and coupled thereto, and wherein the first gearbox and the second gearbox each are coupled to one or more gearbox accessories.

Abstract
The present disclosure is directed to a gas turbine engine including an engine shaft rotatable with at least one of a fan section, a compressor section, or a turbine section, and an accessory gearbox assembly including a towershaft, a first gearbox, a torque transfer assembly, and a second gearbox. The towershaft is rotatable with the engine shaft and extended therefrom and mechanically coupled to the first gearbox. The first gearbox transmits mechanical energy from the engine shaft via a first shaft defining a first end and a second end. The first shaft extends at the first end from the first gearbox and through the torque transfer assembly and coupled thereto. The first shaft extends from the torque transfer assembly to the second gearbox at the second end and is coupled thereto. The first gearbox and the second gearbox each are coupled to one or more gearbox accessories.
