Aircraft Dynamics

The 1st edition of Aircraft Dynamics: from Modeling to Simulation by Marcello R. Napolitano is an innovative textbook with specific features for assisting, motivating and engaging aeronautical/aerospace engineering students in the challenging task of understanding the basic principles of aircraft dynamics and the necessary skills for the modeling of the aerodynamic and thrust forces and moments. Additionally the textbook provides a detailed introduction to the development of simple but very effective simulation environments for today demanding students as well as professionals. The book contains an abundance of real life students sample problems and problems along with very useful Matlab codes.
