Green Regional Aircraft: Vibro-acoustic tests performed on One Piece Barrel


In the framework of Clean Sky’s Green Regional Aircraft platform (Low Weight Configuration domain), vibro-acoustic tests on the composite fuselage barrel demonstrator have been completed in the Leonardo Aircraft Division plant. These tests, performed to evaluate the acoustic and damping performances, belong to a more extensive test plan aimed to validate, at Full Scale Level, such a solution for a Regional Aircraft configuration. The next step is the pressurisation tests phase: fatigue (90000 cycles) and static (Limit Load & Ultimate Load) on configuration including Barely Visible Impact Damage (BVID) due to impacts, manufacturing defects and advanced Structural Health Monitoring (SHM) technologies for damages monitoring.
