This work presents the prediction and the optimization study of noise produced by rotors of a new concept of transport: UAV (Urban Air Vehicle). This project of UAM (Urban Air Mobility) evolved in the recent years due to the overcrowding of the cities’ roads; this is a solution that at the same time brought up to light different issues and one of these, main theme of this document, is the noise pollution. However, the ability to rapidly assess the performance of these new generation of vertical lift vehicles, with sufficient fidelity, is a current weakness of this nascent industry. For this reason, the intention of this study is the prediction of the noise produced by the rotor itself, the study of minimization and optimization of the noise sources.
