航空发动机燃油管路系统温度特性研究
Research on temperature characteristics of aeroengine fuel pipeline system
摘要
Abstract
The aeroengine fuel pipeline system provides the fuel for aviation engines,and is an important compo-nent of aeroengine.To explore the changes in fuel temperature characteristics in aeroengine fuel pipeline systems,based on the basic structure and working principle of the fuel system,a simulation model of the aviation engine fuel pipeline system is established using AMESim.Based on heat transfer theory,the important components such as fu-el pumps,heat exchangers,and return pipelines in the system are studied under flight conditions.The temperature characteristics of the system are studied,and the parameter sensitivity analysis is conducted.The results show that the speed of the fuel pump and the temperature of the aviation lubricating oil are the two most significant factors affecting the temperature characteristics of the system among various components.After the pump speed exceeds 6 000 r/min,the fuel temperature rise rate accelerates,and the fuel temperature at the nozzle can reach 140℃.There is a linear positive correlation between the system fuel temperature and the temperature of the aviation lubri-cating oil.关键词
