Rolls-Royce and Hispano-Suiza (Safran) have named their joint venture Aero Gearbox International and have recently announced plans to construct a new production plant in Poland.

The news follows the signing of a final agreement, on 24 October 2014, to create a jointly-owned company that will design, develop, produce and support accessory drive trains (ADTs) for all of Rolls-Royce's future civil aircraft engines.

The new venture will capitalise on its parent companies' combined experience and expertise, encompassing the capabilities of Hispano-Suiza in the design and production of accessory drive trains, and the engine design and propulsion system integration skills of Rolls-Royce.

Based on an initial exclusive 25-year contract, Aero Gearbox International will cover the entire range of civil aircraft, from business jets to widebody commercial jets. Accessory drive trains, sometimes referred to as accessory gearboxes, are a critical component of a gas turbine engine, harnessing its power to drive systems and accessories such as fuel pumps, hydraulic pumps and electrical generators.

The accessory drive train for the new Trent 7000 will be one of Aero Gearbox International's first products.

Rolls-Royce and Hispano-Suiza will manage Aero Gearbox International's operations. The joint venture will initially have a total of 60 employees from the two parent companies spread across Colombes (near Paris, France), Derby (UK) and Dahlewitz (Germany). It is headquartered at Hispano-Suiza's site in Colombes.
