Abstract

Among the EU funded projects that aim at developing a new concept of tilt-rotors, the pre-competitive ADYN project (Advanced european tilt-rotor for DYnamics and Noise) has the objective to study the dynamic and acoustic problems of the ERICA concept proposed by AGUSTA. This paper presents the work package 3 (WP3) of the ADYN project devoted to aero-acoustics. First a description of the studies done in WP3 is done, giving an overall view of the objectives of this work package. Then, the numerical optimization performed within the project is described. The aim is to reduce the noise generated by the tilt-rotor while improving the aerodynamic performance, starting from the reference blade description up to the ADYN optimized blade selection. Finally, numerical studies of more advanced tilt-rotor blades including adaptive devices are presented.
