Inside power transmissions systems

The accessory gearbox (AGB) taps power directly inside the engine through a radial driveshaft (RDS), to drive fuel pumps, power generators, lubrication system, the starter, oil trap and other engine accessories and the aircraft's power generation system. The complete assembly supplied by Safran Transmission Systems is called the accessory drive train (ADT).

Safran Transmission Systems is the world's leading supplier of mechanical power transmissions for mainline commercial jets (over 100 seats), with production of more than 2,300 shipsets per year. By the end of 2014, these systems had logged a cumulated total of 850 million flight-hours. Safran Transmission Systems equipment has been chosen by two of the world's leading engine-makers, CFM International and Rolls-Royce, clearly reflecting the top-flight reliability of our systems. When you choose Safran Transmission Systems, you choose a dependable, responsive and innovative partner.
