Innovative approaches for interior Noise Control for Next Generation Civil Tilt Rotor The aim of the topic is to investigate the following subjects:• Advanced Transfer Path Analysis (ATPA) applied to a Tiltrotor in order to allow more precise quantification of airborne and structure-borne transmission paths and related ranking in a more sophisticated way compared to a standard TPA.• Advanced active control systems to mitigate tonal noise associated with turbo-propeller BPF (fundamental blade passing frequencies and harmonics) sources, in order to improve cabin comfort at low-medium frequency range (up to 300÷400 Hz), where passive solutions are not effective. The innovation is also related to specific customization as far as new smaller transducers, lower cost and weight components, increased reliability, etc.Please refer to the full topic descriptions document published in this call.
