The noise footprint of a commercial passenger aircraft depends on several parameters. The sound travels through vibrations, which are displacements in a rigid body. These variables are described by the structural models depending on the structures itself and on other parameters. In this paper we apply an innovative shell model, based on Carrera's Unified Formulation, on a cylindrical structure.
