Vibrations, Acoustic And Thermal Exterior Annoyances

ATPI project aims at setting up a Shared Cost Project which goal is to find a new technology of damping treatment providing high vibration and thermo-phonic performances in association with present blanket used for aeronautic applications.

It will lead to better insulate the cabin from both vibrations, acoustic and thermal exterior annoyances. Furthermore, as it will be placed below the glass wool, it will prevent from capturing humidity.

The purpose of the project is to research and find a new light damping technology adapted to thin shell structure (fuselage skin) including noticeable thermo-phonic insulation performances.

The technology will be based on ARTEC patented damping surfacic technology, which reduces significantly noise and vibration levels of thin shell structures, providing unexpected performances.

The latter developed for general vibration issues of thin shell structures, is not suitable for aerospace use and, therefore, a research must be done towards new materials along with new assembling phonic insulation and stringent environmental conditions.

Combined with standard acoustic material (glass, wool, ...), the global solution will therefore drastically increase the thermo-acoustic performance.

Community as well as passenger acceptance is essential for the commercial success of a new aircraft. Hence, environmental cabin comfort issues are important for any turbofan or turbo-propeller aircraft - from business jet to large civil transport - and are becoming more and more important as a market factor.

These small range and small capacity aircraft are more and more necessary but their main drawback is the passenger comfort that must be improved.
