Modeling and Evaluation of Reliability in Rocket Engine by Fault Tree Analysis

Abstract

Recognition of any type of failures in systems and prediction of its reliability have important role in improvement of design of systems. Fault Tree Analysis (FTA) is one of the best techniques in analysis and improvement of complex systems. In this paper first, we show reliability block diagram (RBD) of Rocket Engine and then its fault tree is analyzed. Finally based on FTA, reliability of combustion of rocket engine is calculated.
