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).
While ATR and Bombardier continue to vacillate over plans to introduce a new 90-seat turboprop, Pratt & Whitney Canada keeps moving forward with an engine 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 likely an eight-blade propeller
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.
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.
The FAA proposes to adopt a new airworthiness directive (AD) for certain Honeywell TPE331-5, -5A, -5AB, -5B, -10, -10R, -10U, -10UF, -10UG, -10UGR, and -10UR turboprop engines. It was prompted by engine propeller shaft coupling failures, leading to unexpected propeller pitch changes and resulting in high aerodynamic and asymmetric drag on the airplanes using these engines. This proposed AD would require removing from service certain part number propeller shaft couplings.
The Turbomeca Arrius 2R turboshaft made its first ground run on April 29 at the company’s test facility in Bordes, France. The derivative engine, which is in the 500-shp class, will power the in-development Bell 505 Jet Ranger X light single. The Arrius 2R features Fadec and a 3,000-hour time between overhaul. Certification is expected late next year.
The Textron AirLand joint venture said its Scorpion light strike and intelligence, surveillance and reconnaissance (ISR) jet has completed 50 hours of flight-tests since it first flew on December 12 last year. The prototype has flown to 30,000 feet and at 120 to 310 knots calibrated airspeed, with a maximum airspeed tested of 430 KTAS.
