随着复合材料、全权限发动机控制技术、集成模块化航电等先进技术的大量应用,民用飞机对闪电间接效应防护的要求也越来越高。闪电间接效应防护的关键是闪电防护需求的确定和闪电防护指标的制定。该文从适航指标到需求确定,乃至闪电间接效应防护指标预估进行了研究,用于飞机设计初期在缺乏试验数据和分析条件下的闪电间接效应防护设计开展。虽然此方法获得的结果不能完全与实际状态一致,但简单有效,仍不失一个好方法。
With the extensive application of advanced technologies such as composite materials, full-authority engine control technology and integrated modularization avionics, the requirements for lightning protection of indirect effects of civil aircraft are also getting higher and higher. Indirect lightning protection lightning protection is the key to the protection needs of the lightning protection indicators and the establishment of indicators. This paper studies the prediction of lightning indirect effect protection index from airworthiness index to demand determination and lightning, which is used to design the lightning indirect effect protection in the early stage of aircraft design in the absence of experimental data and analysis conditions. Although the results obtained by this method can not be completely consistent with the actual state, but simple and effective, still a good way.
