民用飞机机翼区域液压系统闪电防护设计研究

Research of Hydraulic System Lightning Protection in Civil Aircraft Wing

民用飞机液压系统作为机翼燃油箱区域内布置的主要系统之一,其相关的闪电防护设计对机翼燃油箱防爆有着重要作用。本文结合液压系统布置原则,运用EMA3D仿真软件对机翼燃油箱内液压导管电流、电压进行仿真,重点研究了液压导管的搭接对闪电防护的影响。

Due to be one of the main systems disposed in wing fuel tank, hydraulic system lightning protection design is very important to aircraft fuel tank protection. Based on hydraulic system layout and software EMA3D, the lightning currents and voltages on hydraulic pipes inside of the fuel tank are simulated, and the bond of hydraulic pipes impact on lightning protection is the focus in this paper.
