摘　　要：以某涡扇发动机为研究对象,建立其各子部件模型,然后通过求解共同工作方程组建立发动机整机稳态及过渡态模型,求解方法采用Broyden法。对模型分别进行了多点稳态仿真以及动态仿真,结果表明,该模型能够执行发动机稳态及过渡态性能计算;结果显示该模型的稳态建模误差在3%以内,动态建模误差在5%之内。Taking a turbofan engine as an object,each sub-component is modelled,and then the steady state and transition state models of the whole engine are established by solving the common set of working equations,and the Broyden method is adopted for the solution.The multi-point steady state simulation and dynamic simulation are carried out respectively,and the results show that the model is capable of performing the steady state and transitional state performance calculations of the engine;the results show that the steady state modelling error of the model is within 3%,and the dynamic modelling error is within 5%.
