FACC develops and manufactures innovative translating sleevesFACC is a partner of Goodrich Aerostructures in the development and fabrication of the translating sleeves for the Boeing 787 and Airbus A350.
In the development of the translating sleeves FACC combines proven technologies with completely new design aspects. The carbon fiber component consists of the visible surface of the thrust-reverser, the moveable blocker doors, the acoustical treated inner duct and the mechanical connection that is needed to operate the thrust-reverser doors.
A newly developed, double-degree acoustic surface, with the Boeing 787 used for the first time on an airplane, marks an important technology jump. In this process a wider frequency band will be covered by including two noise reduction ranges and the noise will additionally be reduced by two steps. The acoustic surfaces are the result of numerous tiny drillings - 1.8 million per engine - through which the sound waves can penetrate into the sandwich area and be confined, and broken into a number of small sound waves.
In the thrust-reverser of the 787 engines, the acoustic surfaces will cover over 80% of the surface. As a comparison, in the present state-of-the-art technology, this percentage is between 60 and 70%. The Boeing 787 will be the first plane with an undulated engine nozzle (chevron). The wave shape at the end of the engine allows the hot air coming from the engine to mix easier with the cold outside air. As a result, the noise level is considerably reduced for the passengers inside the cabin.
