Abstract

Counter-rotating open rotor (CROR) propulsion systems are a promising concept to reach a resource efficient transport demanded by the European Commission in the Horizon 2020 framework program. Due to their fuel efficiency they are actually discussed as an alternative to common jet engines. The disadvantage of CROR engines is the radiation of annoying multi-harmonic noise which leads to high sound pressure levels in the cabin. The impact of the CROR engines on the sound pressure level in the cabin can be reduced by the integration of an Active-Structural-Acoustic-Control (ASAC) system in lining panels. By means of sensors, actuators and a controller the ASAC system is able to increase the sound transmission loss of the panels. Within the scope of the Horizon 2020 ACASIAS project research is performed to integrate the associated wiring, sensors and actuators in lining panels directly. Concepts are explored to realize a seamless integration during an industrial manufacturing process. The integration of an ASAC system in lining panels will enable the installation of fuel efficient propulsion systems. This presentation gives an overview of the current status of the related work package 3 of the ACASIAS project.
