摘　　要：采用部件法建立了某涡轴发动机的起动模型,研究了温升对起动过程的影响,考虑部件特性在低状态下的变化和边界、环境条件对各截面输出参数的约束,给出了某发动机的起动仿真结果。仿真结果表明动力学起动模型能够对发动机的起动过程进行真实的模拟。The thermodynamic real-time mathematical model of aeroengine starting process was established. It is based on component characteristics and it is part of the full-state thermodynamic mathematical model. The influence of temperature rise on starting process was studied with the component characteristics change at low part power condition, the boundary condition and the atmospheric condition constraints taking into account. The simulation results are presented, and they prove that the mathematical model can simulate the engine starting process satisfactorily.
