摘要
针对某型涡扇发动机整机地面台架试车中遇到的喘振故障,从研究多级轴流式压气机在低转速下发生喘振的机理出发,查找发生喘振故障的根源。分析发动机试车中喘振前后所采集到的数据,确认高压压气机可调导向器叶片角度及转差不合适是导致喘振故障发生的主要原因。
Typical turbofan engine surge was described and analyzed during ground bed test. The reasons resulting in the surge were found out according to the acquired data, and the measures were provided for troubleshooting.
