Software Design on Dynamic Simulation of Flight for a Certain UAV

Software design on dynamic simulation of flight is an important part of hardware-in-loop simulation of flight control system for UAV. In order to develop a practical flight dynamic simulation software for UAV, considering the real-time and precision of flight dynamic simulation for UAV, real-time simulation of flight dynamic nonlinear model for UAV is studied based on four order Runge-Kutta algorithm. A kind of practical flight dynamic simulation software for UAV is designed and developed and applied to hardware-in-loop simulation experiment of flight control system for UAV successfully. The testing results show that the software design on dynamic simulation is reasonable and satisfied with the requirements of flight simulation quality, with further engineering applications.
