摘　　要：基于SIMULINK平台搭建了分轴燃气轮机稳态、过渡态仿真的数学模型,利用该模型进行燃气轮机-螺旋桨共同工作动态仿真,分析了螺旋桨角度瞬态变化对燃气轮机性能的影响。在燃气轮机性能曲线网图和压气机特性线图中得到燃气轮机工作过程,并得到螺旋桨角度瞬态变化对燃气轮机性能参数的影响。The mathematical model of the steady state and transition state simulation for the separated-spool gas turbine was constructed based on the SIMULINK platform.The operational dynamic simulation of the gas turbine and propeller was conducted by the model.The influence of the transient variation of the propeller angle on the gas turbine performance was analyzed.The operation process of the gas turbine was obtained by the performance curve graph of the gas turbine and the characteristic graph of the compressor,and the influence of transient variation for the propeller angle on the performance parametersof gas turbine was obtained.
