摘　　要：仿真验证是飞行控制系统设计中不可或缺的环节。利用飞行仿真计算机和飞行控制计算机搭建重复使用运载器(RLV)进场着陆仿真验证平台,并针对FlightGear开源、扩展性强的优点,借助FlightGear外部输入输出接口,将飞行仿真计算机数据通过UDP网络通信协议驱动FlightGear可视化引擎,全面展示飞行位置、飞行姿态以及任务场景,验证飞行控制策略的合理有效性,为完善飞行控制系统提供支撑。Validation and simulation is an essential process in flight control system design. Integrating flight simulation computer and flight control computer, a RLV Approaching ＆ Landing simulation and validation platform is built. In light of advantages of FlightGear＇s open source and strong expansibility, flight simulation data is sent through UDP network communication protocol by means of the input/output interface of FlightGear, so as to drive FlighGear visualization engine. Visual simulation could show the flight position, attitude and the task scene of RLV. Meanwhile, the effectiveness and rationality of flight control strategy is also validated, which provides support to perfect the flight control system.
