CFM International announced on the eve of the show that it had closed the sale of Leap-1A engines to Pegasus Airlines for its Airbus A320neo/A321neo orders. The Snecma-GE joint venture also gave an update on Leap-1A testing. Separately, the French state has announced a divestiture of at least 3.6 percent of shares in Safran (Snecma’s parent company).
With initial running of the new Leap-1 engine on schedule in September, CFM International (CFMI) has embarked on an “unprecedented” level of testing that should involve 20 developmental units by the end of next year and seven of the remaining eight planned examples before 2016 (when a final powerplant will take part in a short exercise–possibly a Leap-1C blade-out check).
Snecma is about to carry out further tests on a one-fifth scale model of an open rotor engine, in a research and technology effort that epitomizes how laborious developing a new commercial engine concept can be.
Liebherr-Aerospace (Booth C11407) may not be a household name in the U.S., but the company is a supplier of numerous components used in aircraft for most of the major aircraft and missile manufacturers in the world, and has been doing so for more than 50 years. In a 58-page promotional magazine created specifically for NBAA 2013 visitors, the company lists 26 aviation customers, from Airbus to Thales.
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.
