A320系列飞机燃油系统常见故障签派放行处置研究

针对A320系列飞机不同机型燃油系统构型存在差异，不便于签派放行处置的问题，提出了A320系列各机型常见故障的签派放行处置方法。首先，系统总结了A320系列飞机各机型燃油系统的布局、供油部件和供油逻辑，指出了各机型可能出现的故障类型和引起故障的机理。其次，分析了可能影响航空公司运行的常见故障，以供油的原理和逻辑为基础，根据构型不同指出对运行影响最大的两个部件为中央燃油泵和传输活门。再次，提出了不同故障条件下签派员的处置方法。最后，以飞机处于签派放行阶段、起飞阶段、中央油箱燃油部分消耗阶段和中央油箱无油阶段为例分别进行分析，进行算例分析说明。结果表明，所提方法能够有效指引签派员处置中央燃油泵或传输活门出现常见故障。

Research on dispatch of common faults in A320s fuel system

To solve the problem caused by different layout of fuel systems of A320 series, the disposal method of common malfunctions of A320 series was put forward. Firstly, the layout, fuel supply components and logic in fuel supply system of A320 series aircraft were systematically summarized. Secondly, the common malfunctions that may affect the operations were analyzed. According to different layouts, it is pointed out that the two components that have the greatest impact on operations are the central fuel pumps and transfer valves. Thirdly, the disposal methods of dispatchers under different fault conditions were put forward. Finally, an example was given to illustrate the aircraft in the dispatch stage, take-off stage, no fuel stage in the central tank and the consumption stage of the fuel in the central tank. The results show that the proposed method is systematic and comprehensive, and can effectively guide the dispatch and disposal to deal with common malfunctions of the central fuel pump or transfer valve.
