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

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

Moruzzi Martino Carlo

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