基于光纤通道的光传飞行控制系统通信方案

为了解决传统电传操纵系统抗电磁干扰能力差、带宽低等问题,提出了飞行控制系统光传方案。作为新一代飞行控制技术,光传操纵有许多电传不可比拟的优势。以一个实际的伺服系统为例,阐述了光传飞行控制系统的基本原理,深入论证了光传飞控系统的关键元器件和关键技术,对几种光传总线的主要特性以及光传总线的拓扑结构、余度方案等进行了分析比较。该系统通过实现了一个基于光纤通道协议的原型系统得到验证,已成功应用于飞行控制系统与飞行仿真系统之间的通信。

Communication scheme of fly-by-light flight control system based on fibre channel

A fly-by-light flight control system was developed to replace the fly-by-wire system which is susceptible to electromagnetic interference and has low bandwidth. This paper describes the fundamental principle of fly-by-light implemented on a servo control system and the key components and technologies of the fly-by-light flight control system. The topologies and redundancy schemes of various fibre optical networks are then analyzed to identify the best system for the fly-by-light system. The fly-by-light system is demonstrated with a prototype based on fibre channel protocol which has been applied to communications between flight control system and flight simulation system.
