Abstract

Abstract

In order to apply condition based maintenance (CBM) to control civil aeroengine time on wing (TOW), the features of aeroengine CBM and TOW were discussed, and the proportional intensity model was established to describe the relation among TOW, condition monitoring variables and failure intensity. TOW control limit due to performance deterioration and optimal preventive maintenance (PM) interval under minimizing expected total maintenance cost per unit time were implemented. The operation data of a CF6-80C2A5 engine were studied. It is pointed that the less failure intensity is, the lower TOW control limit is; moreover, the cost rate between PM and corrective maintenance can affect optimal PM interval; sufficient engine operation data are the keys of accurate TOW control, such as engine removal and on wing history records, maintenance cost, requirements of airworthiness and manufacturer, and time limits of life limited parts etc.
