CFM International claims it is behind a revolution in the use of advanced materials for its Leap series of engines for single-aisle aircraft, that gives it a durability and maintainability edge over the competing Pratt & Whitney PurePower geared turbofan.
As Pratt & Whitney Canada (Chalet (A) 330) saw revenues from its business jet engine segment suffer through one of the industry’s steepest downturns in history, the company’s highly diversified product line has allowed it to, as P&WC president John Saabas put it, “ride the wave” of fortune in other sectors and consolidate its leading position in the small engine business.
Pratt & Whitney CEO David Hess doesn’t spend time lamenting his company’s decision to forgo a bid for a place on Boeing’s proposed 777X. In fact, during a recent interview with AIN at his company’s campus in West Palm Beach, Florida, Hess expressed not an inkling of regret, evidently taking comfort in the narrowbody market’s virtually unequivocal acceptance of his company’s geared turbofan platform. “Our plate’s pretty full right now,” said Hess.
Embry-Riddle Aeronautical University in Prescott, Ariz., will incorporate five turbofan components from previously repaired engines, a donation from Snecma America Engine Services (Sames), into its aerospace and mechanical engineering programs.
The donated items (a fan shaft assembly, thrust bearing, compressor rotor shaft, fuel manifold ring and high-pressure turbine rear shaft) came from a CFM56-5A, the engine that powers single-aisle aircraft such as the Airbus A319 and A320. The components will help expand engineering students’ understanding of turbine engines.
The first quarter of 2013 was mixed for used business aircraft sales, according to the latest market update report from Amstat (Booth 931), although the good news is that inventories of used aircraft continue to drop from the 2009 highs.
The Tech 800 core engine demonstrator made its first run last month at Turbomeca’s Bordes, France headquarters, the company announced last week. A high-pressure spool for the 1,100-shp engine class, the Tech 800 is a precursor to the engine manufacturer’s TM800 Arrano. The Arrano turboshaft will power the Eurocopter X4 medium twin, a Dauphin successor planned for 2017.
Despite some vacillation on the part of airframe OEMs still studying the form their respective 90-seat turboprop might finally take, development of Pratt & Whitney Canada’s engine offering continues on what company vice president of marketing Richard Dussault called a critical path leading to expected launch next year.
Diamond Aircraft is exhibiting a mockup of a DA50 single with a 450-shp Motor Sich-Ivchenko AI450S turboprop engine this week at Aero Friedrichshafen 2013 in Germany. This engine would improve the performance of the seven-seat airplane, which was announced in 2006 with a 275-hp diesel engine as the DA50 SuperStar. Since then the SuperStar’s development stalled and it has yet to be certified, even though this milestone was originally planned for mid-2010.
Jim Rice, chairman and CEO of VisionAire Jets, surfaced at ABACE 2013 this week in Shanghai to market the benefits of a single-engine jet and tell potential investors about the program. VisionAire Jets is developing the all-composite Vantage Jet, which will be powered by a single Williams International FJ33-3AP turbofan and fly up to 1,500 nm with a pilot and five passengers.
Raisbeck/Hartzell swept-blade “turbofan propellers” entered service this month on a King Air B200. This aircraft is also the first installation of the Epic Platinum Performance Package with the new swept-blade props.
