摘　　要：介绍了可靠性指标的确定及可靠性的主要参数,基于国外军用航空发动机可靠性参数体系和指标的统计、分析,针对我国国情提出了军用航空发动机可靠性参数体系和指标确定的建议。发动机配装飞机类型的不同及一架飞机配装发动机的数量不同,对可靠性指标有不同的要求;在其它指标要求相同的条件下,高可靠性意味着低寿命、高成本。所以必须综合考虑可靠性指标与飞行安全、寿命成本间的关系。The determination of reliability targets and main parameter is discussed ,and then a statistic analysis is made on the reliability targets and parameter system of national aero-engine .On the base, the suggestion about the determination of reliability targets and parameter system in Chinese military aero-engine is proposed. There is different requirement about reliability targets when the engine is installed on the different aircraft and the number of engine which is installed on an aircraft is different：The high reliability means low life and high cost when other targets is same. So it is necessary to consider synthetically the relation between reliability targets, flight safety and life cost.
