To answer the request of our customer, Metravib carried out measurements on the plane engine in operation (ground tests). To complete these measurements, Metravib also carried out hammer tapping measurements. Thus the engine exhaust line was instrumented and excited in an artificial way (impact hammer). The whole series of the measurements carried out allowed FT Mesures to better master the vibration behavior of this exhaust line in operation.
These measurements contributed to obtaining an additional qualification issued by the European Aviation Safety Agency (EASA), which allows Atelier Chabord to install this new exhaust system on all F260 aircraft (and more specifically 35 F260 aircrafts of the Italian Air Force).
