French engine manufacturer Snecma has been selected as the sole powerplant supplier for the new Dassault Falcon 5X, which was unveiled earlier this week here in Las Vegas. The new Silvercrest turbofan, rated at 11,450 pounds of thrust at takeoff and with a thrust-to-weight ratio of five, is expected to be certified in 2015. It will be the culmination of a 10-year effort, as Snecma began considering designing its first business jet engine in 2005.
“We are providing Dassault with an integrated powerplant system [IPPS],” Silvercrest program general manager Laurence Finet told AIN, adding that it represents a “plug-and-play” propulsion system for Dassault. Fellow Safran group member Aircelle is supplying a long, mixed-flow nacelle for lower noise and better performance, Finet said. The thrust reverser is Aircelle’s Planar exit rear target design, which has two blocker doors that serve as the engine’s exhaust exit during flight. Also part of the IPPS are engine soft mounts to improve passenger comfort as well as part of the cabin environmental control system.
