Turbine Engine Accessory Drive Gearbox

A Turbine Engine Accessory Drive Gearbox (also known as an AGB or APU gearbox) is a component of a gas turbine engine that transfers power from the engine's main shaft to various accessories and systems. It is typically located at the front of the engine and is driven by the engine's high-pressure turbine.

The accessory drive gearbox is responsible for driving various engine accessories, such as the generator, hydraulic pump, fuel pump, and air conditioning compressor. It is designed to transmit power efficiently and reliably to these accessories, ensuring their proper operation.

The gearbox consists of a series of gears and shafts that transmit power from the engine's main shaft to the accessory components. It is designed to handle the high speeds and torque loads generated by the engine, while also providing the necessary reduction in speed for the accessories.

In addition to power transmission, the accessory drive gearbox also incorporates lubrication and cooling systems to ensure proper operation and longevity. It is typically designed to be durable and require minimal maintenance, as it is a critical component of the engine's overall performance and reliability.

Overall, the turbine engine accessory drive gearbox plays a crucial role in the operation of a gas turbine engine, enabling the efficient and reliable operation of various accessories and systems.
