M-346 Simulator Model: development of the mathematical model of the flight dynamics

Flight simulators are nowadays used as powerful professional training tools and also as entertainment tools, and this has led to a strong rise in the development of high-fidelity simulators with a large aircraft collection. The simulator allows to reproduce the flight of a plane by noting the aerodynamic parameters characteristic for that aircraft in different flight conditions through an appropriate mathematical model of flight dynamics. In literature it is possible to find mathematical models for the aircrafts that result to be the most long-lived and the most studied, while such models are not available, for example, for military aircrafts of new generations. To this last category, the advanced military trainer M-346 aircraft belongs object of study of this thesis. The purpose of this thesis is to develop the mathematical model of the flight control system useful to define the flight dynamics of the M-346 for an entertainment flight simulator. In order to reach such scope, it has been started from the realization of the CAD of the aircraft in scale 1:1 and submitting the obtained element to fluid dynamic simulations with the purpose to obtain forces and moments applied to the aircraft. Several fluid dynamic simulations have been conducted in order to consider the different flight regimes and thus allowed to cover the whole flight envelope. From the results all the needed parameters are obtained for the mathematical model that tries to reproduce the behaviour of the aircraft in flight as close as possible to the real case. The resulting mathematical model can be used to evaluate the responses of the aircraft to the given commands.
