摘要
给出了发动机燃烧室及涡轮导在后冷却空气掺混的解析模型。依照气体热力学 原理及发动机的主调节计划,利用系统数学软件Mathematica推导出描述发动机平 衡工作的方程式。给出了发动机控制输入和性能参数之间的解析关系式。通过与发 动机数值模型计算结果的比较,验证了该解析模型的正确性。
The analytic models of an engine combuster and the mixture of cooling air with burning gas behind turbine vane were given. Depended on the gas thermodynamic principles and engine control conditions, by using of , the analytic equations of an engine under balance working condition were deduced. Then the analytic relations between performance parameters and control inputs of the engine were presented. A comparison of this method with the results of numerical model calculation was made, and the accuracy of the analytic modeling was proved.
