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. 123), the core’s architecture and integration have thus been validated. All performance objectives have been “met and, in most cases, exceeded,” said François Planaud, the company’s general manager for commercial engines. Detailed analysis of the test results is on-going. The Silvercrest, with a thrust range of 9,500 pounds to 12,000 pounds, targets super midsize and large business jet applications.
