Research on aircraft optimal maintenance cycle based on probability and maintenance economy

Abstract

Abstract:

Aircraft airworthiness management of CAAC has been carried out for more than 20 years and remarkable achievements have been initially established,setting up a reliability centered aircraft repair management and repair management mode. But in the actual aircraft repair work,the aircraft system safety,reliability,maintainability and economy must be taken into account. Starting from rate of cost or expense and the efficient use of time from aircraft systems or components of the unit,the theoretical analysis model and analysis method are set up,using the optimization criterion to calculate the aircraft system scheduled preventive maintenance and repair cycle with the minimum average cost rate;in order to achieve the most economic and optimal repair cycle,these are important bases of revised "repair scheme"and "reliability scheme",but also foundation to ensure the flight safety.

Key words: aircraft, onboard system, probabilistic views, optimal maintenance cycle
