The aeronautical sector through CS2 Work Programme aims at contributing to one of the key Societal Challenge ‘smart, green and integrated transport’ defined in H2020, enabling cutting edge solutions to decrease the environmental impact of the sector and to achieve the ACARE 2020 goals, that include 50% cut of CO2 and 80% of NOx consumptions as well as 50% of noise reduction.

CS2 affords the development of different technology demonstrators to advance towards the mentioned objectives. PIANO is framed within Fast RotorCraft Innovative Aircraft Demonstrator Platform (IADP), although new methods and developments involved shall also have an impact on other kinds of aircrafts. The rotorcraft segment of the aircraft manufacturing sector has many applications across civil transport. They perform missions which no other aircraft type can accomplish, operating in all types of hostile environments and weather conditions.

PIANO is related to JTI-CS2-2019-CFP10-AIR-02-82 topic (Innovative approaches for interior Noise Control for Next Generation Civil Tilt Rotor). In terms of interior noise, there are important challenges to overcome. Noise sources in tilt-rotors are significantly different from those from other types of aircrafts as helicopters, with an important increase of air-borne noise. So, the need for the quantification of the type of noise becomes crucial to obtain a reliable modelisation. This is proposed to be done through ATPA, as set in the topic scopes. At the same time, classical passive noise solutions are not effective enough to decrease interior noise levels, so an advanced ANC approach has to be explored and adapted to this environment. PIANO aims at developing suitable methods and tools to understand the noise transmission paths at the tilt rotor and apply the most optimal approaches in ANC, both from local and global point of view, to deal with these challenges to meet market’s needs and to increase EU competitiveness.
