摘　　要：系统建模与数字仿真是大型客机飞行管理系统研发的重要阶段.初步建立了基于航空电子全双工交换式以太网(AFDX,Avionics Full-Duplex Switched Ethernet)的飞行管理系统分布式实时仿真系统模型.对飞行计划、飞行导引、轨迹预测、性能计算、综合导航、导航数据库、综合显示等核心功能进行了分析建模和算法开发.并在此基础上对飞行管理计算机、综合导航系统、自动飞行系统等仿真子系统进行了设计,在满足实时性要求的前提下,基于AFDX网络与分布式仿真结构实现了对以飞行管理计算机系统为核心的航空电子仿真系统的集成,给出了一种通用的、基于AFDX网络的飞行管理系统分布式仿真框架.仿真系统的运行结果证明:基于AFDX网络的分布式仿真结构能够有效满足实时性要求,提高网络通信性能.Modeling and digital simulation are important phases in the development cycle of the civil flight management system.The distributed real-time simulation structure of the flight management system was proposed.The core function modules of the flight management system including flight planning,flight guidance,trajectory prediction,performance calculation,navigation,navigation database and display were modeled and the simulation algorithms were developed.Based on the avionics full-duplex switched ethernet（AFDX） protocol,the simulation module of the flight management computer,integrated navigation system and automatic flight control system were designed and integrated into the distributed system.A generalized AFDX-based distributed simulation system framework of the flight management system was presented.Simulation results demonstrate that the distributed AFDX-based framework can be implemented in real time applications with improvements on the performance of the network.
