Snecma’s ground test facility in Villaroche, France, reports that CFM International’s LEAP-1B engine has completed a successful test run. The LEAP-1B will power the 737 MAX. CFM ran the first ground test on 13 June, three days ahead of schedule. Tests are expected to continue in the coming weeks while CFM verifies mechanical operation, stall margin and engine starts. New technologies to be tested in the engine include a woven fibre composite fan, ceramic matrix composite shrouds and the titanium aluminide blades in the LPT.
