摘要

从热力学、气体动力学和发动机基本原理出发

对基于流量法的齿轮传动涡扇发动机动态性能建模技术展开了研究

并推导出了基于流量法的齿轮传动涡扇发动机动态数学模型的求解方程组.基于该模型方程组

利用C++面向对象编程语言

建立起了某齿轮传动涡扇发动机的动态模型.该发动机动态模型与著名的商业化发动机性能计算软件Gasturb 10进行的比对显示:该模型的运算结果与Gasturb 10的运算结果具有良好的一致性

最大误差不大于1.5%.证明了基于流量法的齿轮传动涡扇发动机动态数学模型求解方程组的正确性和适用性.

Abstract

On the basis of thermodynamics

gas dynamics and gas turbine principles

a detailed research on how to model the transient performance of a geared turbofan engine was performed

and the relevant solver equations were deduced simultaneously by employing constant mass flow (CMF) method in the paper.A geared turbofan engine transient model was successfully coded by means of employing the solver equations and C++ programming language.On the comparable basis

the calculation results have quite remarkable consistency with those results calculated by Gasturb 10

a famous commercial software in aero-engine performance simulation

with maximum errors within 1.5%.Hence

these consequences show the correctness and applicability of the solver equations.
