摘要
通过对运七飞机发动机起动过程的分析,阐述了飞机在起动中的4级过程:转子回路传入电阻RST,电枢串联电阻起动;切除电阻RST,起动发电机增速;两组电瓶串联升压;切除并励绕组成串联电动机工作,使发动机起动顺利完成。掌握飞机发动机的起动过程,对从事飞机制造的调试和维修人员有一定的借鉴和帮助作用。
Through the analysis of electric power startup process of engine of Y- 7 aircraft, the article elaborates on the four-grade process in the startup： startup through the transmission of rotor circuit into the resistance RST in series connection with armature; remove the resistance RST and accelerate the generator; two groups of accumulators boosting up; engine starting to work. The mastery of the startup process of aircraft engine can be of reference and help for debugging and maintenance personnel engaged in aircraft manufacturing.
