Analysis of ACE Modeling and Mode Conversion Process Characteristics with FLADE
为实现新型航空发动机模式转换过程,以一种带FLADE构型的自适应循环发动机为研究对象,在MATLAB/Simulink平台建立该构型三外涵模式动态数学模型,使用此模型仿真了单+第三外涵模式转换为三外涵模式的动态过程.在地面工况的仿真结果显示:该构型发动机总涵道比由 1.365 增加到 1.416,三外涵模式与单+第三外涵模式相比推力降低了 0.933％,单位燃油消耗率减少了 1.600％.
In order to achieve the mode conversion process of a novel aviation engine,an adaptive cycle engine with FLADE(Fan on Blade)configuration is studied,and a dynamic mathematical model of the configuration's triple-bypass mode is established on the MATLAB/Simulink platform,by which the dynamic process of converting single add third bypass mode to triple-bypass mode is simulated.The simulation results under ground conditions show that the total bypass ratio of this engine is increased from 1.365 to 1.416,the thrust of the triple-bypass mode is reduced by 0.933％compared with the single-add-third bypass mode,and the specific fuel consumption is reduced by 1.600％.
