Reductieaarding in cabine zonder geluid gecontroleerd door nieuwe luidsprekeruitschakeling (CONCERTO)

The current race for green mobility is changing the design philosophy in all engineering disciplines; this is tangible especially in aeronautical segment, where optimization and innovation are the key for a sustainable future mobility. In addition, the comfort of passengers is a critical issue for both, manufacturer and airlines, and the noise levels in the passenger cabin of turbopropeller-driven aircraft are typically higher than the levels in comparable turbofan-powered aircraft. The sources of noise in a turboprop aircraft include boundary layer flow noise, structure-borne noise due to engine vibration, and acoustic excitation of the fuselage due to the propeller, with the latter being dominant for most turboprop aircraft. According to Clean Sky program, this proposal aims to develop innovative technologies that will be used in the next genaeronautical transports. The activities related to the CONCERTO project are focused on the development of an innovative cabin/fuselage noise testing equipment for regional aircraft platforms.
