摘要
为借鉴国外航空发动机在设计、研制和使用中积累的经验与教训,通过大量的数据统计与分析,描述美国F-15与F-16战斗机及其装配的F100与F110发动机在使用中发生的重大故障,归纳并总结这些故障在不同阶段、不同部件、不同影响因素的分布情况与规律.分析表明:发动机在前10年或工作35 000 h左右,故障率高,在之后的较成熟期,故障明显减少;无论是否考虑结构完整性,发动机各种故障会出现在整个使用过程中,但按结构完整性大纲研制的发动机的故障率明显低;在部件故障分布方面,发动机叶轮机是最主要的故障源;在影响因子分布方面,设计、维护、保障和使用不当是发动机出现故障的最主要原因.
With reference to foreign experience on fighter engine design and development, the critical failures of F-15 and F-16 fighter powered by F100/F110 engine during - eration were described based on a great deal of data statistics and analysis. The distribution and respective rules of the failures during operation phases, various components and influential factors were analyzed and concluded. The analysis shows that the failure rate of the engine is high within initial 10 years or 35 000 flight hours, then significantly decreases; various engine failures can be exposed during operation, but the failure rate considering the structure integrity is obviously lower than that without considering the structure integrity; the compressor and turbine are main sources of failures; the design, maintenance, support and operation are main influential factors.
