Tackling the noise within aircraft
Is there a way to tackle noise inside tiltrotor aircraft? The lack of acoustic comfort in the passenger cabin is a demanding and challenging issue in this kind of aircraft. The EU-funded project, PIANO, aims to make progress on this question by bringing together Advanced Transfer Path Analysis (ATPA) and Active Noise Control (ANC) technologies. ATPA will be applied to get thorough knowledge of the vibro-acoustic characteristics of tiltrotors. Prior to this, a clustering technique will be implemented to divide the tiltrotor into a set of vibro-acoustic subsystems. Based on the outcomes of the ATPA, innovative ANC techniques will be applied to reduce tonal and broadband noise at a reasonable cost, while keeping an eye on the aircraft weight.
