闪电是自然界常见的一种物理现象,据统计,全世界每秒可发生几百次闪电。雷击的结果或多或少都会影响飞行安全,对闪电效应的分析是评估闪电防护的基础。本文介绍了闪电对飞机的危害和闪电分区技术的相关概念,综述了近年来国内外有关飞机闪电分区适航验证技术应用的研究成果及其发展前景。指出我国在飞机闪电分区技术研究方面主要存在以下问题:一是闪电防护分区技术相关适航规章与文件体系还尚未完善;二是闪电分区技术研究手段单一,集中在实物试验方面,尚未针对性开展仿真及数值分析技术研究。最后,结合闪电防护发展中存在的问题及其最新研究成果,提出了仿真模拟应与实物试验并重的设想,为飞机适航验证技术的发展提供参考。
Lightning is a common physical phenomenon in nature, according to statistics, the world can occur hundreds of lightning per second. The result of a lightning strike more or less affects flight safety and the analysis of the lightning effects is the basis for evaluating lightning protection. In this paper, the related concepts of lightning damage and lightning partitioning technology are introduced, and the research results and development prospects of aircraft lightning partitioning airworthiness verification technology in recent years are summarized. It points out that there are mainly following problems in the study of aircraft lightning partitioning technology in our country: First, the relevant airworthiness regulations and file system of lightning protection zoning technology have not yet been perfected; secondly, the lightning partitioning technology research method is single and focused on physical test, Research on Simulation and Numerical Analysis Technology. Finally, based on the existing problems in the development of lightning protection and its latest research results, the concept that both simulation and real experiment should be taken as equal emphasis is put forward to provide a reference for the development of aircraft airworthiness verification technology.
