FACC delivers the 1,000th outer bypass duct for BR710 Rolls-Royce engine

The long and successful partnership between FACC AG and the engine manufacturer Rolls-Royce is celebrating a significant milestone. Today FACC officially handed over the 1,000th outer bypass duct for a BR710 engine to Rolls-Royce. Since October 2001, FACC AG has been producing these weight-saving, sound-absorbing components for the BR700 engine family. The outer bypass duct will be delivered to the Rolls-Royce plant in Dahlewitz, Germany.

Just recently Rolls-Royce further expanded its cooperation with FACC by awarding the company with a contract for the supply of the outer bypass ducts for the BR725 – the newest of the BR700 engine family, still in the development stage. This new contract boosts FACC's market leadership in the development and production of engine nacelle components using advanced composite technology.

In turbofan engines, the outer bypass duct channels the outer air flow (bypass flow or secondary air flow) past the core engine. The fan works like a sheathed propeller and produces around 80% of the propulsion, depending on the model. Innovative Technology for Efficient, Eco-friendly Engines For years, and in cooperation with engine manufacturers, FACC has been intensively researching the area of engine and engine nacelle components. The focus of the R&D is on improving the efficiency and environmental soundness of new engines that feature reduced fuel consumption and produce less noise and pollutants. By using more composites in engines, the total weight and fuel consumption of the aircraft can be reduced. Due to their design, their material properties and the processes used, composite components can significantly minimize the noise levels of planes. In the production of engine nacelle components, FACC uses innovative manufacturing processes that are unique in Europe, among others a special technology for the processing of acoustic, noise-absorbing surfaces for engine nacelles.
