H2020-JTI-CS2-2019-CFP10-AIR02-82: Innovative approaches for interior Noise Control for Next Generation Civil Tilt Rotor

Clean Sky 2 is a Joint Technology Initiative (JTI) that aims to develop and mature breakthrough ‘clean technologies’ for Air Transport. Clean Sky 2 will deliver breakthrough technologies for incorporation into the next generations of aircraft from 2025 onwards. By spearheading European aeronautics research culminating in demonstrations of game-changing new vehicle configurations, Clean Sky 2 will enable the aeronautics industry to introduce innovations in timescales that would otherwise be unachievable. In so doing, it will drive environmental improvements, increase transport efficiency, and create jobs and growth for Europe.

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.

Type of action: Research and Innovation Action.
