Abstract

An aero-engine fuel system is an important part of an aero-engine, and its reliability directly affects the operation of the aero-engine. To improve the reliability of aero-engines, this paper uses Goal-Oriented (GO) method to analyze the reliability of an aero-engine fuel system with afterburner combustion chamber. Firstly, the GO model is established by the structural schematic diagram of an aero-engine fuel system with an afterburner combustion chamber, and the qualitative analysis and quantitative calculation are carried out according to the operation rules of operators and signal flows in the GO model. Then the minimum cut set and quantitative reliability level of the fuel system are obtained respectively. Finally, the results are compared with the results by the fault tree analysis (FTA) method. The comparison result shows that the reliability analysis of the aero-engine fuel system by the GO method is reasonable and the GO method can be used for the reliability analysis of aero-engine systems.
