Fixed-wing aircraft interactive flight simulation and training system based on XNA

In order to reduce the cost of flight test and enhance the skills of manipulator, a kind of new solution of unmanned aerial vehicle real-time flight simulation and training system based on XNA framework was put forward. the function module and the structure of system were brought forward, and key technologies such as dynamics and motion model, control interface, human-computer interaction function and visual display were discussed and implemented as well as relevant algorithms. In the dynamic model, the standard four element method was used to describe the attitude angle and the differential equations were solved by the fourth-order runge-kutta method; In the visual module, the principle of infinite terrain generate 3D terrain surface and particle system generated some effects such as rain, snow, fog and explosion et al.; In the control module, the human-computer interaction function was achieved by Instructor class of the XNA framework interface. Finally, the system development was realized based on Visual Studio environment and C# language, flight training was simulated in this system by manipulating the handle and controlling the interface, and the feasibility and validity were verified.
