The paper presents a numerical study about a de-icing system using ultrasonic waves. The activity is developed within the project “SMart On-Board Systems” (SMOS), which is part of Italian Aerospace National Research Program, funded by the Italian Ministry of Education (MIUR) and Research and coordinated by Italian Aerospace Research Centre (CIRA). The system is conceived for an aircraft wing leading edge and it shall be extended to other aircraft components, once its efficiency and reliability will be demonstrated. In this work, a numerical study about a 0012 NACA profile in composite material is discussed and the simulations results coming from finite element analyses in frequency and time domains are presented.
