CONDITION-BASED MAINTENANCE DECISION MAKING METHODS FOR CIVIL AEROENGINE
摘要
Abstract
To provide some feasible condition-based maintenance (CBM) decision making methods for civil aero-engine,firstly,the theory of aeroengine CBM decision making is described.The proportional intensity (PI) model is established based on the reliability and condition monitoring data.According to the model,the decision making methods are proposed for the optimal preventive maintenance (PM) interval and removal.Then,the time on wing(TOW) is predicted by collecting actual data based on the engine age and operating conditions.Finally,an exam-ple of a fleet for CF6-80C2 engines is illustrated.It shows that sufficient engine operation data are the key of ac-curate decision making.Results indicate that the CBM decision making methods are helpful for engineers in air-lines to control engine maintenance actions and TOW,thus decreasing risks and maintenance costs.关键词
