Accessory gearbox and gear-train

The accessory gearbox is a key module in modern jet and turbofan engines. Its function is to transfer mechanical power from the engine shaft, through a properly designed gear train, to different shafts, rotating at selected speeds, with accessories and components like starters, hydraulic pump, etc.

Avio is a world class leader in this product on both commercial and military applications, supplying such modules for all the major engine manufacturers. On the "big" commercial turbofan (>60000 lbs thrust) Avio maintains the highest share of this specific market world-wide.
