通航飞机直流电源系统原理及常见故障分析

Principle and Common Default Analysis of Direct Current Power System of General Aviation

针对典型通航飞机直流电源系统的组成、结构、功能和工作原理进行论述,对近三年该系统出现的各类故障按照机载蓄电池、发电机及电源控制组件和供电网络三大子系统进行详细分析,统计各子系统故障次数及故障原因,并找出引起该系统故障的主要影响因子——发电机系统及供电网络。

For the typical aviation direct current system, the constitution,construction,function and principle is introduced. The default from three sub-systems-airborne battery,generator and power control unit and supply net- work in the latest three years is particularly analyzed. The frequency and causes of the three subsystems are counted, the main factors causing the system failure-the alternator system and supply network are found out.
