摘　　要：在飞控系统半实物仿真中,航电系统与地面其它模拟系统涉及多种网络联接,如何选择并协调相关网络通信、构建它们相互之间数据流的实时转发平台并实时驱动航电仪表是设计航电模拟系统的关键。为了满足某型飞机飞控系统实时仿真试验的需要,综合应用实时网、1553B和以太网等三种网络方法并结合虚拟现实技术开发了飞机航电模拟器,既加快了开发进度和节省了开发成本,又比传统的航电系统更具扩展性,应用效果良好。Avionics system is linked with several other equipments such as flight computer, simulation computer in the hard-in-loop simulation of flight control system, and it is important to establish a pla（form to coordinate the networks and manage the data-exchange between them for avionics system design. An avionics system simulator integrated in RTNET, 1553B, Ethernet and virtual reality technology was studied and realized to meet the simulation demand of a flight control system test, and it shows good effectiveness and expansion.
