Abstract�� The simulation model of turbofan engine for ground starting was described. The simulation is based on thermo-aerodynamics relationship, the components’ characteristics, experienced formulas. According to being given known condition and fuel regulation, the starting has been simulated by integral method. In order to show the effect of the simulation, the results of the simulation model calculated have been compared with the testing results. The compared result shows that the simulation model can simulate mixed flow turbofan engine with afterburner for ground starting effectively. These parameters and coefficients have been analyzed, including calculating time interval, the rotation speed of the starter off, experiential coefficient of combustion total pressure recovery coefficient, the environment temperature and pressure, the airport attitude. The results show that these parameters and coefficients have significant effect on ground starting simulation.
