某型发动机亚热带岛礁气候下的可靠性分析与保障

针对某型航空发动机及其备件驻岛礁保障数量决策困难问题,在分析发动机于亚热带气候条件下使用的可靠性基础上提出保障率概念,运用量子粒子群优化求解方法,在重点关注发动机备件重要性、可维修能力、故障程度等因素前提下,结合发动机2级维修保障体制,给出了发动机及其备件基地级保障和不同驻岛时间内的携行保障策略,为实现飞机驻岛礁的发动机常态化优化保障提供参考。

Reliability Analysis and Support of an Aeroengine under Subtropical Islands Climate

Aiming at the difficult problem of decision-making for optimal number of an aeroengine and its spare parts, the concept of support rate was proposed on the basis of analyzing the actral soperation reliability of the engine under subtropical climate. By using quantum particle swarm optimization method, combined with two-stage engine maintenance and support mechanism, the base level support strategy of engine and its spare parts and the carrying support strategy in different station time are given, while considering the importance, maintainability, failure degree and other factors of engine spare parts. The research result provides reference for normalizing optimal support of aeroengine when stationed at islands and reefs.
