Vibro-acoustic analysis and design optimization to improve comfort and sustainability of future passenger aircraft

Abstract. The challenges of recent years lead to the development greener aircraft. However, concept environmental sustainability cannot be declined on its own; economic is also required by increasing services provided passenger, particularly comfort. This work aims propose a design process for new sustainable aircraft that takes into account both sustainability, reducing aircraft's emissions with configuration, and introducing series solutions increase comfort during flight, particular attention acoustic comfort, i.e. internal noise.
