Maiden flight of the Dassault's newest Falcon 5X business jet has been delayed by two years, following persistent developmental issues with the Snecma Silvercrest engine.
The engine needs additional developments to optimize and extend operational life says Snecma, which has been flight tested for 500 hours and ground tested for 3500 hours since first run in Oct 2012.
Snecma now anticipates engine certification in first half of the 2018.
The engine issue emerged shortly after 5X's roll out in June 2015. Dassault had earlier planned the jet's first flight in the third quarter of 2015 and was scheduled to enter service in 2017.
The Falcon 5X is a twin-engine business jet featuring a large cabin and long range of 5,200 nautical miles at Mach 0.80 speed.
The Silvercrest engine for Falcon 5X develops 11,450 lb of thrust and will decrease fuel consumption and CO2 emissions by about 15% and reduce NOx (oxides of nitrogen) emissions by 50% in relation to current CAEP/6 standards, while reducing noise by 20 dB versus Stage 4 requirements.
Snecma started developing the light, compact turbofan with a bypass ratio of 6:1 using 3D Aero design technologies in 2010.
The high-pressure compressor features four single-piece 'blisks' and a centrifugal stage, while the high-pressure turbine has an active clearance control system, another first in this type of engine, for even greater internal aerodynamic efficiency.
Silvercrest® was also chosen to power Cessna's Citation Longitude business jet, but later switched to a Honeywell engine after the aircraft was redesigned.
