Abstract


Aircraft engine fuel control and regulation systems (referred to fuel transfer system) is the core system of the engine, has a very important position. In routine maintenance, the ability to timely diagnose faults, periodic maintenance and repair fuel transfer system can be maintained in working condition and performance of normal, and whether the normal and safe operation of the aircraft closely. This paper analyzes the fault diagnosis fuel tune the necessity and feasibility, and analyzes the domestic fuel tune on studies to determine the content to be studied in this paper, routes and methods. Secondly, this paper studied the fault tree analysis related technologies, and to the theory of fault tree analysis and calculation done related instructions; also establish and fault tree analysis were studied. Thirdly, based on analysis of the requirements of the aircraft for fuel transfer on the basis of analysis of the basic theory and typical fuel adjustment works, from fuel transfer system fault diagnosis to start an in-depth study of fault tree analysis and decision support system based on to find both the starting point, proposed the establishment of fuel transfer system fault diagnosis and repair of decision support systems. Fourth, analysis and research decision support system in order to repair the fault tree and fuel transfer knowledge linking finalized troubleshooting and repair fuel transfer decision-making systems, and the feasibility studies. The system through the fuel transfer system fault tree accumulation of knowledge, so that troubleshooting repair site can quickly diagnose the fault tree to call in order to improve maintenance efficiency; while regular maintenance to provide basis for decision making. The system has a fault diagnosis, system maintenance, data query and other functions, the use of human-computer interaction operations. This a lot of work in the following three aspects: First, the fault tree analysis and decision support system based on the proposed based fault diagnosis and fault tree maintenance decision system design; Second, the Windows XP operating system environment to sharepoint development tool as a front to the C programming language for the software development tool, SQL server 2000 for the database tools to achieve the basic functions of the system; three in a typical fuel conditioning system fault diagnosis and repair of decisions to explain the system to reach effect. Thesis addresses two aspects of key technologies: one is based on the knowledge of the structure of the fault tree design; two is in line with the characteristics of the fault tree reasoning mechanism design. The innovation of papers mainly in two aspects: First, integration of fault tree analysis and decision support systems both technologies, the establishment of fuel adjustment based on fault tree troubleshooting and maintenance decision support system; Second is to strengthen the knowledge base expansion make fault diagnosis and maintenance decision system has a skeleton system features easy system and the gradual improvement in the relevant field gradually applied.
