Safran Transmission Systems - The power transmission specialist

Safran Transmission Systems is the world's leading supplier of power transmissions (also known as accessory gearboxes, or AGB) for mainline commercial jets with over 100 seats, and supplies these systems for all types of aircraft.

Safran Transmission Systems designs, produces and supports the transmissions that provide the mechanical energy needed for aircraft and their engines. Power transmissions by Safran Transmission Systems outfit all types of aircraft, from business and regional aircraft to military transports, and from mainline commercial jets to fighters and helicopters.

The company's proven expertise has led to its selection on many of today's leading aircraft programs. Safran Transmission Systems provides power transmissions for the entire range of CFM56* engines, for all three versions of its successor, the LEAP*, for the engine powering the Airbus A350 XWB, and for the engines on the Gulfstream G650, the Airbus Helicopters EC175 and the Rafale's M88-2. Its clientele includes the engine-makers Safran Aircraft Engines, CFM International and Rolls-Royce, and the plane-makers Airbus, Boeing, Bombardier and Dassault Aviation. Safran Transmission Systems offers a full range of support services, from one-time repairs and spare parts to total fleet support and "by the hour" packages.

Safran Transmission Systems mainly operates at two sites: Colombes, near Paris, which handles R&D, design, production, sales and support of power transmissions for airplane and helicopter engines; and Sedziszow, Poland, specialized in the production of gears, cases and components for nacelles and aircraft engines. Safran Transmission Systems also produces parts for other Safran companies.

A significant part of Safran Transmission Systems' annual revenues is reinvested in R&D, enabling the company to develop new, differentiating technologies for tomorrow's aircraft. Research at Safran Transmission Systems focuses on innovative systems to tap and transmit power, and on highly loaded mechanical power transmission systems.

Safran Transmission Systems has some 1,600 employees in France and Poland. To date, it has delivered over 36,000 power transmissions, logging more than 1 billion flight-hours.

* The CFM56 and LEAP engines are produced by CFM International, a 50/50 joint company between Safran Aircraft Engines and GE.
