Falcon F7X/F8X nacelles and duct

High performance nacelles

Safran Nacelles’ Dassault Aviation Falcon 7X/8X nacelles are manufactured using a significant amount of composite materials. They integrate a 2-door PERT® thrust reverser (Planar Exit Rear Target), as well as a thrust reverser attachment flange made using RTM (Resin Transfer Molding) technology and participate in the reduced noise footprint of the Falcon 7X/8X propulsion system through their composite-material acoustic skin.

The thrust reverser as a braking mechanism on landing

The thrust reversers ensure braking of the plane, especially on short, wet, snowy or icy landing strips.

Safran Nacelles has  expertise in the assembly of aerostructures such as thrust reversers. The company has control over all the parts assembly processes: they are positioned meticulously, adjusted to the structure using shimming, drilling, milling, countersinking, bonding and riveting.

Nacelle integration on the engine and final assembly line support

All nacelle components - air inlet, fan cowl, thrust reverser, nozzle and EBU* - are assembled on the engine at Safran Nacelles’ integration site in Toulouse (France). This is where the final adjustment operations between the nacelle, the engine and the mast that will connect the propulsion system to the aircraft fuselage, are carried out before being transferred to the Dassault Aviation Final Assembly Line (FAL) in Mérignac (France) where support is provided by Safran Nacelles’ teams.

*EBU: Engine Build Up, regroups several items: electric harnesses, pipes, circulation valves, air inlet anti-icing system, electric feed, etc.
