  • 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.
