许多舰外检测器与主平台之间要求高带宽数据链路,它一般采用动态施放的光纤。如果放线系统损害了链路的完整性,那么整个链路就会失去作用,而且很可能会危及整个使命,甚至导致检测器的完全失效。英国国防研究署(DRA)目前正在致力于放线可靠性的研究。该机构已经研制出了计算机数学模型,用来预测由于放线路径配置不同在光纤内累积的拉力。此外,还设计了在光纤放线实验设施上可进行的一系列试验,并以各种不同的放线路径及构件复现动态放线过程。还根据实验大纲对计算机数学模型进行了验证并对失效模式与信号衰减等结果进行评估。本文详细介绍了计算机数学模型和实验装置以及根据实验大纲得到的原始数据。
Many shipboard detectors require a high-bandwidth data link with the main platform, which generally uses dynamically cast fiber. If the pay-off system compromises the integrity of the link, the entire link is out of action and is likely to jeopardize the entire mission and even lead to a complete failure of the detector. The Defense Research UK (DRA) is currently working on the study of pay-off reliability. The agency has developed a mathematical computer model to predict the cumulative tension in the fiber due to the different payout path configuration. In addition, a series of tests that can be carried out on the optical fiber take-off test facility are also designed and the dynamic take-off process is reproduced with a variety of pay-off paths and components. The mathematical model of the computer was also verified according to the experimental outline and the results of failure mode and signal attenuation were evaluated. This article details computer mathematical models and experimental setups as well as the raw data obtained from the experimental outline.
