Snecma appears to be giving itself more time before beginning flight-testing of its first business jet engine: the Silvercrest. But the apparent delay in what had been projected at last year’s EBACE show as a first flight in the first half of 2013 will likely have little bearing on the certification path for the new turbofan’s first applications.
Snecma has started running the first Silvercrest turbofan at its Villaroche test facility near Paris, France. With 11,000 pounds of thrust, two of the units will power the Cessna Longitude super-midsize business jet.

EASA engine certification is slated for 2015 and FAA validation is expected shortly thereafter.
Snecma has finally found an aircraft for its Silvercrest engine to power after Cessna announced its selection here yesterday for its Longitude super-midsize jet, which is scheduled to enter service in 2017. It has been almost five years since the French manufacturer announced that it was to develop its first business-jet engine program, but finding its first application has proved to be a frustratingly long road.
Six months after launching its midsize Citation Latitude, Cessna Aircraft today at EBACE announced a $25.9 million stretched version–the Longitude–that will fly 4,000 nm at Mach 0.82. First flight is scheduled for 2016, with entry into service in 2017. “The aircraft is long on range, high on value and low on price,” Cessna president and CEO Scott Ernest said at the unveiling.

Snecma is continuing development of its 9,500- to 12,000-pound-thrust Silvercrest engine for large-cabin business jets and RJs, with certification now expected in the 2013 to 2015 time frame. Disassembly after 80 hours of operation, which took the test engine up to takeoff speed and temperature redlines, showed the engine has exceeded the company’s expectations. The new engine has yet to be chosen for an OEM application.

Snecma launched the Silvercrest core-engine demonstrator program in 2006, built the engine in 2007 and successfully completed testing of it in March 2008. Now the company is continuing its talks with airframers to find a first application for the 9,500- to 12,000-pound-thrust engine. “The Silvercrest is being considered for many programs,” said Laurence Finet, general manager of the Silvercrest program.
Snecma announced here at EBACE that the core demonstrator of its Silvercrest business jet engine has completed a series of tests. The campaign ended on March 31 after four months of trials. The core engine ran 80 hours, including 60 hours ignited. During the tests, the core reached its nominal takeoff speed–20,300 rpm. According to Snecma, a subsidiary of Safran (Booth No.
