摘要
雷电是一种危险现象,但是到目前为止还没有一种技术能够防止飞机遭受雷击。本文分析了雷电造成的危害,并论述了飞机结构设计应该为雷电流提供低阻抗的通路。对于对雷击放电敏感的部位和部件,必须根据其自身的重要性采取适当的雷电防护措施,以尽可能减少雷电对飞机的损害。最后介绍了为确保雷电防护措施的可靠性而进行的验证试验方法。
Lightning is a dangerous phenomenon. But so far no technique can prevent aircraft from being destroyed by lightning. The harm from lightning is analyzed in this paper, and it is demonstrated that low impedance pass should be provided in aircraft design for lightning current.Suitable measure for lightning protection of aircraft must be adapted to the part that is sensitive to discharge of lightning strike, so that the damage to aircraft by lightning strike can be reduced.Eventually qualification test means that assure reliability of measure for lightning protection is presented.
