Safran Nacelles — in its first major role as a supplier to Boeing — delivered the first jet engine exhaust system component for the Boeing 777X on 15th November.
The component was the exhaust system's centre body — a complex-shaped unit that contributes to the aerodynamic flow of exhaust from the aircraft’s General Electric GE9X turbofan engines.
The two-piece exhaust system centre body was delivered from Safran Nacelles' Le Havre, France, production facility. It is composed primarily of titanium and incorporates an acoustically treated area for reduced engine noise levels.
A second development unit is in production at Safran Nacelles for delivery to Boeing before year-end, involving the centre body, the nozzle and the centre vent tube — representing a complete exhaust system.
The 777X's exhaust systems are among the largest of their type ever manufactured for civil aircraft.
