Abstract
With the development of aerospace technology, high reliability and long lifetime are becoming the basic requirements and ultimate goals for aerospace products. The commonly used technique for ensuring the reliability of aerospace systems is setting up the backup systems properly, which calls for particular attention to common cause failure (CCF) problems in such systems. Limitation of experimental and field data introduces imprecision in the performance characterization of components that need to be taken into consideration for assessing the system reliability. In this paper, we adopt the concept of survival signature to estimate the reliability of aerospace systems with multiple types of components. Particular attention is devoted to CCFs, which are modelled and quantified by parametric models. The component importance measure is enhanced in order to assess the importance of various possible CCF scenarios and to identify their potential impact on the system reliability. Uncertainties of CCF events are reduced by Bayesian inference. The presented method is used to analyse the reliability of the dual-axis pointing mechanism for a communication satellite, which is a commonly used satellite antenna control mechanism. The engineering application demonstrates the effectiveness of the method.
