What turned out to be a big week for Boeing with the formal launch of its new 777X widebody also promises to be a big week for the engine that will power it, the GE9X. Dubai Airshow visitors can get a sneak preview of the 102,000-pound thrust turbofan through a new 3-D representation of the equipment at the GE Aviation exhibit (Chalet A9).

In May this year the French-U.S. joint venture CFM International delivered the 25,000th example of its CFM56 turbofan, which powers Boeing Next-Generation 737s and the Airbus single-aisle family. Last month the 10,000th CFM56-7B for the 737 family was delivered, while next month deliveries of CFM56-5s for Airbus will pass 8,500. As well as these two influential single-aisle aircraft lines, the CFM56 also powers the Airbus A340-200/300.
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).
International Aero Engines has launched its new Pure-V designation for V2500 engines maintained to IAE’s build standards, the company announced here in Dubai. A Pure-V-designated engine contains IAE-approved parts and repairs throughout the entire engine.
Rolls-Royce’s strategy of feeding technological developments from new programs back to established engines for upgrades or retrofit changes is creating a range of enhanced-performance (EP) packages being available to customers.
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.
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.
Boeing said it has completed aerodynamics, engine and weight audits that together have given it a clearer picture of the future operating performance of the new 737 Max. The manufacturer now says the re-engined narrowbody will burn 14 percent less fuel than today’s 737-800NG, one percent better than it previously estimated.
