摘　　要：飞机飞行中不可避免产生沉积静电,沉积静电的泄放如果控制不好会严重干扰飞机的通信、导航,影响飞行安全。简要说明了沉积静电的产生与危害,从防护原理入手,详细讲述了控制沉积静电泄放的设备——静电放电器的特性,分析了其形状与组成部分,并给出飞机上配置静电放电器数量的计算方法和布置方法,考虑到闪电的影响,阐述了静电放电器在金属和复合材料表面的安装方法,最后分析了全复合材料静电放电器的优点。Precipitation static is an inevitable phenomenon when aircrafts flying in the atmosphere. If it is not controlled properly, the dissipation of precipitation static will cause severe disturbance to communication and navigation, and affect flight safety. The sources and hazards of precipitation static are explained firsdy, followed by the protection principle. The main equipment of precipitation static dissipation control, i. e., the electrostatic discharger, is introduced, with analysis of its shape and components. The methods for calculating the quantity of the electrostatic dischargers and their collocation on an aircraft are also expatiated. Considering the effect of lightening, the installation of electrostatic dischargers on metal and composite surfaces is also described. Finally, the advantages of all composite material discharger are analyzed.
