Real-time Visual Flight Simulation System Based on Flightgear Simulator

针对国外某型无人飞行器,建立了非线性六自由度飞行模型和自主导航控制系统,在此基础上,利用Flightgear飞行模拟器外部数据输入/输出接口,将飞行仿真数据通过网络实时传递,驱动Flightgear可视化引擎,实现飞行仿真中,飞行姿态、天气条件和地理环境的三维实时可视化显示。仿真试验表明,该可视化飞行仿真系统可扩展性强,开发周期短,系统建设简单,使用方便,为今后的深入研究打下了良好基础。

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 1/0 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.
