发动机地面起动电气控制系统的工作原理分析与研究

【摘要】

本文主要阐述了通过对发动机地面起动电气控制系统电路图的研究说明起动过程的工作原理。本文分为四大部分，地面起动电气控制系统的概况；起动电源的构成和原理；这部分也就是本文的重点部分，详细的分析地面起动电气控制系统的要求及工作情况；最后为维护注意事项。

This paper describes the aircraft engine start-up on the

ground control system start-up process. This article is

divided into six most of the first part of the ground control

system start-up of the situation; second part of the start-up

power supply structure and principles; the third part of that

is the focus of this paper, a detailed analysis of the ground

control system start-up requirements and Work; part of the

fourth set to maintain the attention of the matter; the fifth

part of my writing on the paper gains; is the sixth part of

my words of thanks.
