While ATR and Bombardier continue to vacillate over plans to introduce a new 90-seat turboprop, Pratt & Whitney Canada keeps moving forward with a powerplant it believes will deliver a 20-percent fuel burn improvement over existing engines in the 5,000- to 7,000-shp range by the turn of the decade. Dubbed the Next Generation Regional Turboprop (NGRT), the engine would feature an all-new compressor, a miniaturized version of Pratt & Whitney’s patented Talon combustor and (probably) an eight-blade propeller.
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.
It is ironic that a Scottish entrepreneur who failed to make a success of two innovative aviation projects has had more success in what many would consider the much riskier world of land-speed record breaking.
A qualified pilot, Richard Noble created ARV Aviation in 1983 to design and build an all-British light aircraft: the Super2, which was powered by a Hewland AE75 three-cylinder two-stroke engine, but only 35 were made before production ceased.
As preparations continue for running a full open-rotor engine demonstrator in 2016 under Europe’s Clean Sky research effort, French engine maker Snecma (Hall 4 Stand B12) sees the program’s participants reaching a consensus as whether or not to proceed in the 2017-to-2019 time frame. Clean Sky, which also involves Airbus, Rolls-Royce and French research center Onera, has provided a relatively unexpected discussion platform, thus facilitating a general agreement.
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).
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).

Engine manufacturer GE Aviation on Monday gave an update on its class H series turboprops, which are powering four aircraft for their first flights this year.
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.
