Airbus began immediate processing of flight-test data from the A320neo’s September 25 first flight, which Single Aisle program experimental test pilot Philippe Pellerin described as “a lot of fun” as he emerged from the aircraft at the Toulouse-Blagnac factory in southwest France. The first A320neo, powered by Pratt & Whitney PW1100G-JM geared turbofan (GTF) engines in the 33,000-pounds thrust class, “really feels like an A320–which is good news,” remarked fellow experimental test pilot Etienne Miche de Malleray, who occupied the right-hand seat.

Airbus flew its new A320neo on its first test mission on Thursday, marking the start of a 3,000-hour flight-test program scheduled to lead to certification and entry into service in next year’s fourth quarter. Powered by a pair of Pratt & Whitney PW1100G geared turbofans, MSN6101 took off from Toulouse-Blagnac Airport in France at noon local time.
The second Bombardier CSeries CS100 flight-test vehicle returned to the air on September 7 after more than a three-month hiatus. FTV2 took off at 6:10 p.m.
Bombardier confirmed on Friday that the modified Pratt & Whitney PW1524G engines for the CSeries flight-test vehicles have successfully completed the testing required for return to flight test and that the second test vehicle (FTV2) will return to the air this month.
Two manufacturers shared the spoils of Japan Airlines’ major commitment announced last week covering a total of 47 regional jets. But the potentially bigger and undoubtedly more desperate winner proved to be Mitsubishi, the upstart regional jet manufacturer whose orderbook now shows memoranda of understanding, tentative agreements and firm orders from six customers.
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.
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.
