摘要
针对某型辅助动力装置在地面低温起动时多次发生的超温、喘振现象,进行了起动系统工作原理分析,并对比了起动成功和失败时发动机主要参数,详细研究了发生该故障的几种可能性,给出了解决方案。
Aiming at many over-temperatures and surge phenomenon occurred in ground low-temperature starting of an auxiliary power unit,the operation principle of starting system was analyzed.The main engine parameters between some success start and fail start were compared.The several possibilities of this failure were studied in detail,and the solutions were obtained.
