Pratt & Whitney and Alcoa recently have revealed that the fan blades of the PW1000G family of geared turbofans will consist mainly of aluminum alloy–an industry first.

Pratt & Whitney on Sunday announced that is has managed to reduce fuel burn on the PW1100G-JM for the A320neo family by another 2 percent. Dubbed the PurePower Engine Advantage, the enhancement centers on improved aerodynamics and cooling.

Pratt & Whitney officials on Sunday afternoon identified the source of the failure of one of the PW1500Gs on the first Bombardier CSeries flight test aircraft as a “seal issue” in the oil system, not the low-pressure turbine, as was previously indicated by Bombardier. However, the officials refused to specify precisely where the oil leak originated or offer detailed information about the expected timing of its so-called fix.

Pratt & Whitney expects to gain certification of the first version of the PW1100G for the Airbus A320neo during this year’s fourth quarter.

While calling extending its geared turbofan engine family’s thrust rating by another 2,000 pounds “a big deal,” Pratt & Whitney next-generation product family vice president Bob Saia sees still bigger things in the company’s future, including what he called an Advanced GTF that could rival an open-rotor design in fuel efficiency by the middle of the next decade. For now, though, Saia finds himself “busy as a bee” with the five core programs already under way at the U.S. company.

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.

Airbus has finished assembling the first A320neo, the company announced Tuesday. The airplane, MSN6101, rolled out of its paint hangar in Toulouse, France, after receiving its Airbus house livery and installation of its Pratt & Whitney PW1100G-JM engines. The company started final assembly of the first A320neo in mid-March, with the attachment of the forward and aft fuselage sections, made in Airbus facilities in St. Nazaire, France and Hamburg, Germany, respectively.

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.

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.

Pratt & Whitney Canada started running a full PW800 engine demonstrator late last year, company vice president of business aviation and military programs Michael Perodeau told AIN yesterday. He confirmed that the demonstration effort has progressed according to plan but gave little detail.
