APU航线维护策略研究

以APU失效故障的统计分析和翻修经验为基础，分析了导致APU失效的内、外部因素，给出了APU的小时成本估算法。并以减少或削弱失效故障产生根源、提高派遣可靠性、降低综合维修成本为目的，提出了APU的航线使用策略、日常维护与例行检查策略、视情检查策略和排故策略，从而系统地建立了对机队管理和航线维护具有指导意义的航线维护综合策略体系。

Study on APU Airline Maintenance Tactics

Proceeding from statistics analysis of the APU failures and the experience obtained in a preemptive revisionism,this paper analyses the exterior and interior factors leading to APU failure,and gives an algorithm to estimate cost on hourly calculated basis,on purposes of eliminating failures' sources,enhancing dispatching reliability,as well as lowering comprehensive cost of maintenance. This paper also proposes the airlines' APU routine operation tactics,routine maintenance and regular overhaul tactics,conditional overhaul tactics and fault removal tactics. A comprehensive maintenance tactics system is therefore established,with strategically guiding significance to the air fleet management and to the comprehensive maintenance of airlines.
