The fan will incorporate latest technology from the CFM56—the world’s best-selling airliner engine, in which Snecma is a joint partner with GE—as will the low-pressure system. “Silvercrest will be designed for acoustic margins of up to 30 dB below Stage 3 and, for NOX norm in terms of architecture for an engine of this size by choosing to use a centrifugal compressor stage in combination with four axial stages. The centrifugal compressor enables a reduction in stages Philippe Petitcolin of turbo machinery to just 10, compared with 21 stages in the Rolls-Royce AE3007. The other radical feature of the Silvercrest is counter-rotating core and power shafts. “It hasn’t been normal in the past to counter-rotate the shafts,” Cojan said. “We have conducted some research in this area on larger engines for the nextgeneration CFM56. “We are going for proven high technology for extremely high reliability on entry into service, rather than some costly, exotic design,” Cojan said. —John Morris Snecma Silvercrest FUV01 Aviation Week’s Guy Norris and B/CA’s David Esler contributed to this story. First Mustang For Europe The first European Citation Mustang VLJ was officially handed over to pilot/owner Jane Howell at Farnborough this month. Howell gained her FAA license 20 years ago and has since accumulated 1,850 hours, mainly on Cessna piston twins. She says she has flown single pilot all over Europe and intends to continue to do so in the Mustang. Her personal Pilot Proficiency Index dictated that she spend two weeks in the classroom and the Garmin 1000 equipped Mustang simulator, plus 25 hours of Mentor training. After flying her N-registered aircraft in the U.S. and ferrying it back to the UK, she had accumulated 21.5 hours of Mentor flying. “If Cessna hadn’t come up with the Mustang, I probably wouldn’t be in a jet today,” Howell said. She looked at the Beech King Air and other Cessnas, but they were too big for her requirements. “I looked quite closely at the Eclipse 500, but it is much smaller than I specified…and I also thought, is this company going to be here in five years?” The Pilot Proficiency Index, developed jointly by Cessna/Flight Safety International and insurers, identifies the degree and type of training required for individual pilots. —Mike Vines 96 September 25, 2007 www.aviationweek.com/shownews http://www.aviationweek.com/shownews
