机载天线罩雷电防护设计方法及应用

文中对机载天线罩雷电防护的必要性和雷电防护方法进行了研究,根据天线罩遭受雷击后的危害程度,确定其雷电关键性类别。根据此类别、雷电防护成本和防护系统对天线罩性能的影响程度,确定是否采取雷电防护措施。采用不同的雷电防护设计方法解决位于不同雷电附着区的天线罩雷电防护问题。利用经验公式和路径比较两种方法设计分流条布局,并通过实例证明了方法的可行性。

Method and Application on Lightning Protection for Airborne Antenna Radomes

The necessity and method of lightning protection of airborne antenna radomes are studied in this paper. Based on the endangering degree from the antenna radome after being struck by lightning, determine the lightning criticality category. According to this category,lightning protection cost and the influence extent of protection system on the properties of radome,determine whether take lightning protection measures. Different design methods of lightning protection are used to solve lightning protection problems of radomes located at different lightning attachment zones. Strip layout is designed by empirical formula and path comparison method. An example proves that the method is feasible.
