<P>3. Job Set-up<BR>工作准备<BR>A． Not Applicable<BR>不适用<BR>Subtask 05-51-18-210-077<BR>B. General<BR>概述<BR>（1）Lightning<BR>雷击<BR>（a）Lightning always has two or more attachment points (one entry and one exit) on<BR>the aircraft skin.<BR>雷击总是在飞机机体上造成两个或两个以上的雷击点（一个进入点，一个退出点）<BR>（b）Lightning moves back along the surface of the aircraft (swept stroke zone)<BR>between the entry and exit point. This can cause a chain of scattered attachment<BR>points along a line in the direction of travel of the aircraft.<BR>雷击进入点和退出点是沿着飞机（受雷击区域）表面向后移动形成，雷击可能导致<BR>沿飞机飞行方向一连串的雷击点<BR>（c）Lightning hits some areas more frequently than others.<BR>有些区域会比其它区域更频繁遭受雷击</P>
<P>（2）Aircraft zoning<BR>(Ref. Fig. 601/TASK 05-51-18-991-001 SHEET 601.1)<BR>区域划分 (Ref. Fig. 601/TASK 05-51-18-991-001 SHEET 601.1)<BR>（a） The aircraft is divided into three zones related to the probability of lightning<BR>strike:<BR>飞机依据遭受雷击的可能性可以划分为三个区域:<BR>Zone 1<BR>区域 1<BR>- surfaces where there is a high probability of initial lightning attachment (entry or<BR>exit).<BR>这些表面最有可能使雷电在机体上形成附着点（进入或退出）<BR>Zone 2<BR>区域 2<BR>- surfaces where there is a high probability of a "swept stroke zone". The lightning<BR>strike has its initial point of attachment in Zone 1 and moves into Zone 2.<BR>这些表面最有可能使雷击形成连续雷击或多处雷击的情况，雷击进入区域1 后再进<BR>入区域2<BR>Zone 3<BR>区域 3<BR>- this zone includes all of the aircraft surfaces that are not in Zone 1 and 2. In Zone 3<BR>there is a low probability of attachment of a lightning strike. However, high lightning<BR>currents can go through Zone 3 by direct conduction between 2 attachment points.<BR>Zone 3 currents will also go into Zones 1 and 2.<BR>除区域1、2 外的所有表面。区域3 发生雷击的可能性较小，然而,强大的雷击电流<BR>可以在2 个雷击点之间形成直接通路从而进入区域3，同样区域3 的电流也可以进<BR>入区域1 和2.<BR>（b）Zones 1 and 2 are divided into A and B areas related to the probability of continued<BR>attachment of the arc (hang on). The probability of arc hang on is low in A areas<BR>and high in B areas<BR>根据放电电弧的附着可能性又将区域1、2 分成A、B 两个部分。在区域A 形成电弧<BR>的可能性小,在区域B 形成电弧的可能性大</P>
<P>Zone 1A:<BR>区域 1A<BR>- area where there is a high probability of initial attachment and low probability of<BR>arc hang on, such as the forward-mounted pitot probes, the radome diverter strips<BR>and the nacelle leading edges.<BR>该区域具有高的雷击初始附着的可能性,低的形成电弧的可能性,比如迎风安装的皮<BR>托管,雷达罩上的导流条以及吊舱的前缘部分.<BR>Zone 1B<BR>区域 1B<BR>- area where there is a high probability of initial attachment and high probability of<BR>arc hang on, such as the wing, stabilizers and fin tips and some trailing edge areas.<BR>该区域具有高的雷击初始附着的可能性,高的形成电弧的可能性,比如机翼,安定面.翼<BR>尖小翼以及一些后缘区域.<BR>Zone 2A:<BR>区域 2A<BR>- a swept stroke zone with low probability of arc hang on, such as mid-chord<BR>regions of the wing surface, aft of an engine and the total fuselage surface<BR>该区域会形成连续雷击但形成放电电弧的可能性比较小,比如机翼表面中部玄区，发<BR>动机后部以及所有机身表面.<BR>Zone 2B:<BR>区域 2B<BR>- a swept stroke zone with high probability of arc hang on, such as the wing trailing<BR>edge aft of Zone 2A.<BR>该区域会形成连续雷击且形成放电电弧的可能性比较大,比如机翼后缘部分.<BR>（3）Effects on the aircraft structure and systems<BR>对飞机结构和系统的影响.<BR>There are two types of possible risks to the aircraft<BR>有两种对飞机来说可能存在的危险<BR>- indirect effects<BR>间接影响</P>
<P>- direct effects<BR>直接影响<BR>（a） indirect effects<BR>间接影响<BR>Electromagnetic fields<BR>电磁场<BR>- the electromagnetic fields related to the lightning attachment can cause unwanted<BR>transient voltages and currents in the aircraft wiring and systems.<BR>In some conditions (low intensity strike, high protection), the effect on the systems<BR>can be temporary and the systems can operate correctly again after the strike. In<BR>other conditions (low protection, no circuit protection devices), the damage can be<BR>permanent and it will be necessary to replace parts<BR>雷电导致的电磁场可以使飞机的线路和系统产生不必要的瞬变电压和电流。对有些<BR>情况来说（低强度放电，强保护区），对系统的影响是暂时的，系统在雷击之后可<BR>以恢复正常工作。对其他情况来说（弱保护区，没有线路保护装置），遭受损坏是<BR>永久性的，必须更换部件进行修复。<BR>（b）Direct effects<BR>直接影响<BR>The direct effects are the physical damage related to signs such as:<BR>直接影响可以导致如下物理损伤:<BR>1 Pitting/meltthrough<BR>凹陷/击穿<BR>- this is the action of the electrical arc formed when a lightning stroke attaches to the<BR>aircraft (arc root damage at the attachment points or damage caused by current flow<BR>which can appear also far from the attachment points).<BR>该情况是由于飞机在遭受雷击时形成的放电电弧导致的（放电电弧位于雷击附着点或由<BR>于远距附着点的电流造成）<BR>-signs of a lightning attachment are pitting and scorch marks and paint discoloration.<BR>On composite components, in addition to paint discoloration and skin puncturing,<BR>some delamination of the fibers can occur. If there is skin puncturing, there can be<BR>damage to the grounded equipment below composite material fairings.<BR>雷击附着点造成飞机表面凹陷，焦痕或喷漆颜色改变的特征；对于复合材料部件，除了<BR>出现表面穿孔和喷漆颜色改变外，有些化纤材料会出现分层现象。如出现表面破裂情况，<BR>则可能会对复合材料下的接地设备造成损伤.<BR>-you must always compare the damage you find with the limits given in the Structural<BR>Repair Manual (SRM).<BR>对发现的损伤必须与SRM 中所给的限制进行比较</P> :) :) :) :) :lol :hug: 雷击后检查 很关注这个
