基于FlightGear的综合航电主飞行显示器设计

摘要

综合航空电子显示系统作为传统机械式飞行仪表的替代,以数字化、集成化形式提供大量飞行信息.为满足某型通航飞行品质监控平台的需求,应用AC3D软件建立了综合航电主飞行显示器模型;在FlightGear视景系统框架上,完成了基于XML文档的模型驱动开发;借助FlightGear外部数据I/O接口输入飞行数据,实现了飞行数据的数字化、综合化显示.仿真实验证明,显示器界面逼真,能直观地反映飞行过程中的相关参数,实现飞行状态的复现.%As a substitute of mechanical flight instrument,integrated avionics display system provides a large amount of flight information in digitized and integrated form.In order to meeting the requirements of a certain flight operation quality assurance,a model of primary flight display is built by software AC3D, and the model driver based on XML file is completed in the visual system of FlightGear,the digitized and integrated display of flight data is realized with the flight data is input by external data I/O interface of FlightGear.Simulation results show that the display has a realistic interface,which reflects intuitively to the relevant parameters in flight process and realizes the reproduction of flight state.
