Rolls-Royce (R-R) has completed a 1,500-cycle test of its new Trent 1000-TEN engine and is well into the demonstration phase ahead of formal testing in early 2014, according to T1000 program chief engineer Gareth Jones. In mid-October, the initial demonstrator unit was being stripped down in R-R’s development department as the company prepared to assemble a second test engine.
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.
Boeing has increased its estimate of the operating performance of the 737 Max, saying the re-engined narrowbody will burn 14 percent less fuel than the current 737NG consumes. In July, the manufacturer said the 737 Max with new CFM Leap-1B turbofans will be 13 percent more fuel efficient.
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.
GE Aviation (Booth No. N5500) is aiming to grow its Business and General Aviation (and Integrated Systems) business to $1 billion in revenues by 2020 from the $300 million level it is at in 2013. This is already significantly up from the $150 million it turned over in 2008.
Pilatus Business Aircraft is displaying a mock-up of its twinjet PC-24, announced earlier this year at EBACE, here at its NBAA booth (No. C12216) near the indoor static display. A prototype is currently under construction and is expected to fly late next year and certification and first customer deliveries are anticipated in 2017. Three aircraft will be used in the flight test program.
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.
If you already fly or maintain some regional airliners and larger business jets, including the Bombardier CRJ200 and Global Express; Gulfstream IV and V/550; Dassault Falcon 2000EX and 7X; Embraer ERJ 145, 170 and 190; IAI Westwinds and Beechcraft King Air turboprops, you may already be familiar with an innovative, on-wing engine-cleansing system called EcoPower Wash.
Rolls-Royce is preparing technologies for the next generation of business jet turbofans and the design engineers’ motto seems to be “smaller, faster, leaner.” Karsten Mühlenfeld, Rolls-Royce executive v-p of engineering and technology for civil small and medium engines, provided AIN with details on future designs that will feature swifter development cycles, near-perfect reliability and reduced acquisition costs.
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.”
