摘要
分析了带Flade的自适应发动机工作机理,建立了发动机单外涵、双外涵、单外涵+第三外涵以及三外涵等4种工作模式的稳态性能数学模型,对带Flade的自适应发动机在典型工况下的稳态工作进行了数值仿真,对比分析了不同工作模式的工作特点。仿真结果表明,带Flade的自适应发动机能够根据不同工况和性能需求,改变工作模式,在一定范围内维持进气流量,更好的匹配进气道流通能力;单外涵+第三外涵工作模式应用于需要大推力的状态,三外涵模式应用于需要低耗油率的状态,双外涵工作模式则在涡轮前温度达到限制时可以产生更大的推力。
By analyzing the working principle of the adaptive cycle engine with Flade(fan-on-blade),the steady-state performance mathematical models of four kinds of working modes of the engine,including single bypass,double bypass,single-add-third bypass and triple bypass,are established.Under typical working conditions,the steady-state performance of the adaptive engine with Flade is simulated,and the characteristics of different working modes are compared and analyzed.The simulation results show that:the adaptive cycle engine can maintain the inlet flow in a certain range,and obtain better adaptive flow capacity of the inlet.The single-add-third bypass working mode is applied to the state requiring high thrust,the triple bypass working mode is applied to the state requiring low fuel consumption,and the double bypass working mode can produce more thrust when the turbine front temperature reaches the limit.
