摘要
以某型飞机燃油系统设计方案为原型,自供能源式供输网络为特色,建立了各主要部件的数学模型,并采用模块化结构的方法,利用Simulink/Matlab建立了各部件的仿真模块,构成仿真系统进行研究。求解了飞机燃油系统5种供油状态下各节点的流量、压力和温度,并分析了部分换热器参数对换热器有效能损失的影响。上述研究为飞机燃油系统的整体建模和仿真提供了新的思路和方法,同时对燃油系统的有效能分析有一定的意义。
Based on a certain type of aircraft fuel system design for the prototype, and characterized by the self supplied fuel network, the mathematical models of the main components were built. Using the modular structure method, the Simulink/Matlab was adopted for building the simulation modules of various components and forming the whole simulation system. According to the simulation calculation, the flow, pressure and temperature for each node of the fuel system were obtained, and the effects of several parameters of heat exchangers on its exergy losses were analyzed. The present study provides a new method and idea for the modeling and simulation of a whole aircraft fuel system, as well as has some effect on the analyzing the exergy of the fuel system.
