During the starting process of turbofan engine, the optimization of fuel supply in main combustor is an important key technology of successful start.According to the components characteristics of main combustor, and considering the accuracy of the engine control system, this paper puts forward a design method of asymptotic ignition for fuel supply control law.The method mainly includes the basic fuel quantity, the rate of rise and maximum of ignition fuel supply.Based on this, the judgment conditions of successful ignition are presented.It is applied to a certain type of turbofan engine.With the analysis of ground test, simulated altitude test and test flight, the method is proved to be more practical and effective.
