Real-time Visual Flight Simulation System Based on Flightgear Simulator

A nonlinear 6-DOF flight model of an Unmanned Air Vehicle was developed,including navigation and control system. Incorporated with it,flight simulation data was fed to the Flightgear simulator through its I/O port by network. Then Flightgear visual engine was driven to achieve real-time visual flight simulation and the UAV states,weather condition and geographic environment were showed in 3-D model. The simulation results show that this visual flight simulation system is feasible,valid and economic. It can be used as a primary platform for the future work.
