<br/><br/> Airframe noise is a a significant component of the aircraft signature.In this thesis we study the impact of coating airfoils with an acoustic absorbing material.The finite element method (FEM) is implemented to model the homogenous uniform air the non - homogenous flow and the is otropic thin absorbing layer
