摘　　要：提出了一种基于广播内存光纤网的分布式无人机实时飞行仿真系统,通过对系统数据交换网络和功能节点的设计克服了一般的网络环境中存在通信延迟和有限带宽等缺点,使系统实时性和扩展能力都得到保证。系统按照节点功能分为无人机动力学、运动学特性仿真,传感器的仿真,实时仿真飞行数据、飞行轨迹、三维视景显示与数据记录和遥控/遥测与地面检测等部分。半物理实时飞行试验结果表明系统设计正确,满足新型无人飞行器飞行控制系统的内、外回路动态控制功能和性能测试与验证要求。A distributed real time flight simulation system of UAV based on the broadcast memory fiber optics networks was described. The shortcomings of delay in transmission and finite bandwidth in normal networks were overcome by design of computer network and function nodes, which the real-time characteristic and expansibility could be ensured. The system could be divided into the characteristic dynamics and kinematics of UAV simulation sub-system, input and output （I/O） data processing sub-system which the sensors simulation was included, the flight track display and three-dimensional vision of the flight simulation and data store sub-system and the simulation terminal of remote-control and detect device. The correctness of the system design is validated by the results of the real time hardware-in-loop flight simulation test .The test and study of new type flight control system of UAV in dynamic characteristic of inner loop can be fulfilled.
