摘　　要：为实现典型工况模式选取方案,针对一种带FLADE(Fan on blade)的自适应循环发动机展开研究。基于各部件气动热力学原理在MATLAB/Simulink平台建立了该构型3外涵模式整机计算模型。在此模型基础上,通过减少迭代变量与残差变量的思路,分析了该构型在节流过程中两种工作模式不同典型工况下的性能。仿真结果表明:在地面工况条件下,3外涵模式与单+第三外涵模式相比在低转速下推力较高,而高转速下则相反,地面大功率状态起飞可以采用单+第三外涵模式;对推力需求不高的亚声速巡航工况,可在飞机爬升后开启MSV(Mode selection valve)使发动机以3外涵模式工作。To achieve a typical operating mode selection scheme,this paper conducts research on an adaptive cycle engine with fan on blade(FLADE).Based on the principles of aerodynamic thermodynamics of each component,a complete machine calculation model for this configuration with triple bypass mode is established on the MATLAB/Simulink platform.On the basis of this model,the performance of this configuration under different typical operating conditions of two working modes during the throttling process is analyzed by reducing iterative and residual variables.The simulation results show that under ground operating conditions,the triple bypass mode has higher thrust at low speed compared with the single-add-third bypass mode,while at high speed it is the opposite.The single-add-third bypass mode can be used for take off under high-power ground conditions,and for subsonic cruise conditions with low thrust requirements,the mode selection valve(MSV)can be activated to operate the engine in triple bypass mode after the aircraft climbs during the phase.
