S2 Parametric Channel Modeling and Numerical Simulation for a Whole Turbine-shaft Engine

建立了一种涡轴发动机整机S2参数化流道造型方法,采用某S2数值仿真软件完成了某涡轴发动机的整机计算。计算表明S2参数化流道造型方法简单、有效,仿真软件对涡轴发动机进行整机稳态计算的精度基本满足计算要求,为涡轴发动机整机多学科设计优化奠定了基础。

The paper establishes a S2 parametric channel modeling method for a whole turbine - shaft engine by using a certain S2 numerical simulation software to complete the calculation of a whole turbine - shaft engine. Calculations show that the S2 parametric channel modeling method is simple and effective, and the accuracy after simulation software＇s calculating turboshaft engine＇steady state can basically meet the calculating requirement. Thus this may lay a good foundation for multidisciplinary design optimization of a whole turbine - shaft engine.
