Aircelle to supply titanium exhaust systems for engines on the new 777X jetliner

Aircelle (Safran) will produce titanium exhaust systems for the new 777X commercial jetliner, marking the nacelle manufacturer’s first major supplier win with Boeing. These exhaust systems will equip the 777X’s two GE9X turbofan engines from GE Aviation, providing the benefits of lower mass, along with increased resistance to heat with the use of Aircelle processes for titanium high-temperature applications. The exhaust system includes acoustically-treated areas for a reduced noise level signature. Based on its experience and proprietary database, Aircelle has optimized the design and manufacturing processes in metallics for nacelle applications, and developed methods of predicting titanium’s performance in commercial exhaust systems.
