Mathematical Modelling of an Unmanned Aerial Vehicle

This thesis presents the results of a study on the development of a mathematical model of the flight dynamics of a small-scaled aircraft. The aircraft, due to its small size has the potential to be converted to an unmanned aerial vehicle (UAV). A mathematical model of an aircraft flight dynamics...
