Modeling and Simulation for Fuel Distribution of Commercial Aircraft Engine

基于AMESim建立商用航空发动机燃油分配的仿真模型,对不同工况条件下的燃油分配特性进行仿真分析。通过功能、性能等试验数据来对比验证模型,结果表明,建模仿真过程合理、准确,仿真与燃油分配真实工作状态一致。利用模型仿真深入分析燃油分配特性的影响因素,为航空发动机燃油分配的设计、改进提供理论支持。

The simulation model of commercial aircraft engine fuel distribution has been built in AMESim,and used to analyze the characteristic of fuel distribution in several different working conditions.The model has been verified with the test data of the functional and performance test.The result shows that the modeling and simulation is rational and accurate,and the simulation is consistent with the real working state of the fuel distribution.Analyzing the factors which influence the characteristic of fuel distribution by simulation provides theoretical guidance for the design and the optimization of the aircraft engine fuel distribution.
