Computer Modelling of UAV Flight

A technique which uses the method of automatically deriving differential equations of motion for computer simulation of the unmanned aerial vehicle's (UAV) flight, is proposed. To compile them, a special computer algebra system is used. It implements complex analytical transformations of the formal description for the dynamic model of the spatial UAV motion. As an example of using the developed approach, we consider the simulation of the motion of a hybrid multicopter vehicle developed at NTU “KhPI”. This UAV uses an internal combustion engine for lift providing, control and stabilization are performed using electric motors. The design features of the multicopter are described and the obtained equations used to simulate its motion are presented.
