基于光纤传感器的火箭发动机工作状态监控方法研究

发动机的工作状态监控是测控领域的一个难点。针对传统火箭发动机工作状态监控存在的缺陷以及光纤传感器本身所具有的体积小、重量轻、灵敏度高、频带宽动态范围大、抗电磁干扰能力强、耐高温高压等多种优点,提出了基于光纤传感器的火箭发动机工作状态监控系统的设计方案,并给出一种多传感器数据融合实现方法。

Monitoring studies of rocket engine working state based on fiber-optic sensor

Engine working state monitoring is a difficulty in measure and control field. This paper aims at the defect of the traditional rocket engine working state monitoring system. And aims at the various advantage that fiber-optic sensor has, for example： little volume, light weight, high sensitivity, wide frequency band,strong ability to fight electromagnetism disturbs and high temperature and high pressure and so on. This paper makes design scheme of the rocket engine working state monitoring system based on fiber-optic sensor,and explains a realization method of sensores＇ data fuse.
