摘要

摘要: 考虑了容腔的质量和能量的储能效应,提出了基于容积法的涡扇发动机实时数学模型建模方法,建立了容腔压力和温度的微分方程,容腔的压力和温度可以用不迭代的数值法求解.同时,利用C++面向对象编程语言,建立了某涡扇发动机动态模型.用建立的发动机动态模型和商用软件Gasturb 10分别计算了发动机性能,并进行了对比,结果表明:该模型与Gasturb 10的运算结果具有良好的一致性,高压压气机转速、涡轮进口温度及压气机喘振裕度的响应结果最大相对误差小于1%.容积法避免了数值迭代,可以保证模型计算的实时性.

Abstract: The effect of mass and energy storage in a volume was considered. A modeling approach for real time turbofan engine model was presented by employed inter-component volume (ICV) method. The pressure and temperature differential equations were established. The pressure and temperature were calculated through numerical integral without iterative. A turbofan engine transient model was coded by means of employing the solver equations and C++ programming language. By comparison, the calculation results have quite remarkable consistency with those results calculated by Gasturb 10 which is famous commercial software in aero-engine. The simulation results show that the maximum relative errors of high pressure compressor,turbine inlet temperature and the surge margin of compressor are within 1% and ICV method avoids iterative so the computer's running time is evidently reduced.
