By the end of the year, CFM (OE 22) plans to have put together and tested around 20 Leap-1A/B/C turbofans, in preparation for their first flights next year and in 2016 on their respective application airframes. The Franco-American engine manufacturer is also gearing up for a swift production ramp-up, planned to reach an annual 1,700 engines by the end of the decade. The Leap will power the Airbus A320neo (Leap-1A), the Boeing 737 Max (Leap-1B) and Comac C919 (Leap-1C) narrowbodies.
Mitsubishi Aircraft took delivery early last month of its first Pratt & Whitney PurePower PW1200G geared turbofan at the Mitsubishi Regional Jet’s (MRJ) final-assembly factory in Aichi Prefecture, Japan. Delivery of the engine from Pratt & Whitney’s Mirabel Aerospace Center in Quebec marks a major milestone toward final assembly of the first MRJ90 flight-test aircraft, which Mitsubishi expects to fly during next year’s second quarter.
France-based engine developer Price Induction is taking its DGen 380 turbofan on a U.S. tour this month. Exhibited on a mobile test bed, the 575-pound-thrust powerplant and all of its operating equipment have been mounted on a truck platform for the tour. Next stops are Chicago (July 21), Cleveland (July 24) and University Park, Pa. (July 28).
GE Aviation expects this month to fly the Passport engine that will power Bombardier’s Global 7000 and 8000. GE has shipped the first complete engine to Victorville, Calif., where it is about to be fitted to one of the company’s two Boeing 747 flying testbeds.
Price Induction will be touring the U.S. with its twin-spool unmixed-flow, high-bypass-ratio DGen 380 turbofan on a mobile test bed. The DGen 380 targets the personal light jet market, and the associated training solutions can be used by universities, aircraft maintenance schools and research organizations for courses such as engine operation training to acoustics and thermodynamics research. Cities already confirmed for demonstrations include Washington, D.C.(June 27); Chicago (July 21); Cleveland, Ohio (July 24); and University Park, Penn. (July 28).
CFM International has begun ground testing of the first Leap-1B engine developed to power Boeing’s new 737 Max family of narrowbody airliners. The joint venture between Snecma and GE announced today that ground tests began three days ahead of schedule on June 13 and that the 23,000- to 28,000-pound-thrust turbofan already has achieved full takeoff thrust.
The FAA is adopting an airworthiness directive for all Rolls-Royce Deutschland BR700-725A1-12 turbofans. The AD requires removal of affected fuel metering units on the BR700-725A1-12. This AD was prompted by reports of wear on the receptors of the double-ended unions in the FMU housing on BR700-725A1-12s causing fuel leakage. The AD is intended to prevent failure of the FMU, which could lead to damage in one or more engines and damage to the airplane. The AD becomes effective July 17.
Pratt & Whitney’s launch on Tuesday of a 35,000-pound-thrust version of its Geared Turbofan extends the family’s power range by another 2,000 pounds, giving Airbus A321neo customers enough range and payload capability to effectively operate from such hot and high locations as Mexico City and Bogota. Dubbed the PW1135G-JM, the engine gets its extra thrust from leftover development margin extracted from the design of the family as a whole, thereby requiring no hardware or design changes, explained Pratt & Whitney vice president of engineering Tom Prete.
Legendary aircraft designer Ed Swearingen died on Thursday at age 88, on the eve of the resumption of production of his persistent light jet–the SJ30–by current program owner SyberJet. It was 1986 when he unveiled the small, single-pilot jet powered by a new breed of turbofan engine by Williams International that would propel the airplane swiftly and far, with performance that outstripped most business jets of the era.
Most activity in business jet engine research and development is taking place for business aircraft at the top end of the size range. Snecma (Booth 5515) is developing the Silvercrest for the Dassault Falcon 5X, while Pratt & Whitney Canada (Booth 3834) has readied a new variant of the PW307 for the newly revealed Falcon 8X. The Québec-based manufacturer is also running the PW800, a demonstrator in the 10,000- to 20,000-lb-thrust range. GE (Booth 5551) is working on its Passport engine for Bombardier’s Global 7000 and 8000.
