Dassault Aviation’s long-awaited unveiling of the Falcon 5X large-cabin, long-range business jet is being accompanied by a number of Falcon 5X supplier announcements.
Six suppliers contribute to Snecma’s Silvercrest: Aircelle (Safran), nacelle and thrust reverser; Techspace Aero (Safran), lubrication unit, booster, forward sump;
Sagem (Safran), electronic control unit; Liebherr Aerospace, bleed-air system;
Hamilton Sundstrand (UTC AS), accessory gear box; Woodward, fuel pump metering unit, actuators.
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.
Dassault Aviation revealed details of its long-awaited SMS jet today at the NBAA Convention, along with a new name: the Falcon 5X. Development of the jet, which will be powered by two Snecma Silvercrest engines, is well under way, with first flight scheduled for the first half of 2015 and entry-into-service two years later.
Engine manufacturer CFM International reports that the Leap series of turbofans under development for the new Airbus A320neo, Boeing 737 Max and Comac C919 narrowbodies is performing as planned since full engine testing began last month. “I’m proud and really happy to tell you that the engine is running smoothly,” Chaker Chahrour, CFM executive vice president, told reporters in a teleconference on October 16. “This engine wants to run.”
Snecma plans soon to start another phase of open-rotor engine testing using a one-fifth scale model, in a research and technology effort that epitomizes how laborious developing a new commercial engine concept can be. The concept, based on contra-rotating high-speed propellers, may not find itself in service before 2025. Nevertheless, trials aimed at cutting noise while retaining the huge efficiency advantage of the open rotor’s architecture are well under way.
CFM International—the 50-50 joint venture between GE and France’s Snecma—has started testing the first full Leap turbofan engine, the company announced Friday. The Leap-1A—one of the powerplant choices for the Airbus A320neo—fired for the first time on September 4, two days ahead of schedule.
CFM International, the General Electric/Snecma joint venture, expects to begin a second phase of ground testing for its 3-D woven resin transfer molding fan with its Moteur à Aubes de Soufflante en Composite Taille (Mascot) 2 fan-demonstrator engine. The fan is “foundational technology” for the CFM Leap engine that is scheduled to enter service in 2016.
UK aerostructures and equipment group GKN Aerospace has been contracted by Snecma to provide low-pressure turbine (LPT) cases for the Silvercrest SC-2C engine for the Cessna Citation Longitude. Under a long-term agreement valued at $15.7 million, production of LPT cases by GKN Aerospace-Norway for delivery to Snecma’s Villaroche facility will accelerate as the engine is prepared for the Longitude’s scheduled entry into service in 2017.
