CIAM commences testing of new generation Silvercrest engine developed by Safran Aircraft Engines for advanced business jets

14 July 2017


On 28 of June 2017 in the CIAM Research Test Center located in Lytkarino, Moscow region, the first stage of tests has been successfully commenced for the Silvercrest turbojet engine created in France for advanced business jets. CIAM and Safran Aircraft Engines fulfill the program to prove thrust efficiency, operability efficiency and engine reliability under the actual flight conditions simulated in altitude test chamber of the C-4N test bench.


During test preparation, CIAM upgraded the engine air supply system, provided adaptation of the bench equipment for installation and control, as well as for static and dynamic parameters measurement. The unique adapter was designed and manufactured to allow engine installation at the C-4N test bench for the current test cycle and for next test activities at two other test benches of the CIAM Research Test Center, the biggest in Europe, where the startability of the engine in icing conditions will be checked.

For reference:

Silvercrest is a new-generation jet engine, specifically designed and built by Safran Aircraft Engines for premium business jets. The Silvercrest engine has already been chosen by Dassault Aviation for the Falcon 5X. The thrust capacity of the Silvercrest engine is 4,3…5,5 tons. The engine main feature is high bypass ratio – 5,9. The pressure ratio is 38,5. The fan diameter is 1,08 m. The quantity of titan blades is 20. The blades are featured by large width and crescent shape. Innovative technology provides the Silvercrest engine with superiority of effectiveness, reliability and ecology parameters at the business jet aircraft market. In comparison to analog engines, the fuel consumption and CO2 emission have decreased by 15 %, NOx emission level has decreased up to 50 % compared to the ICAO CAEP/6 standard, noise level has decreased by 20 decibel that satisfies the Stage 14 noise standard.
