| 中文摘要: |
| 为了分析某型军用涡扇发动机空中停车的原因，通过自批量装备部队以来发生的空中停车故障，根据历年空中停车率
总结了停车原因的变化趋势，归纳了空中停车率统计结果，分析了影响空中停车率的空中停车事件以及故障件与故障原因，提出了
提高成附件可靠性水平、优化控制规律和加强监控措施等预防措施。结果表明：影响发动机空中停车率的主要因素是控制系统和传
动润滑系统成附件故障与整机喘振裕度低。 |
| 英文摘要: |
| In order to analyze the reasons for in-flight shutdown of a military turbofan engine，the trend of the shutdown reasons was
summarized according to the in-flight shutdown rate in the past years since the batch equipment troops. The statistical results of in-flight
shutdown rate were summarized and the in-flight shutdown events affecting the in-flight shutdown rate as well as the fault parts and the
cause of the failure were analyzed. The preventive measures such as improving the reliability level，optimizing the control rules and
strengthening the monitoring measures were put forward. The results show that the main factors affecting the in-flight shutdown rate of the
engine are the failure of the control system and the lubrication system and the low surge margin of the engine. |
