Abstract

In accordance with the character of the turbojet's starting control law

the power extraction model of acceleration and deceleration control law was used to design the starting control law of turbojet engine.In combination with the low speed component character prediction method and the improved power extraction method

the constrain conditions and design procedures were presented.The model could be used to predict the starter power in the crank process

and design the starting control law in the whole flight envelope and all climate conditions.It is shown that the control law designed with the power extraction method coincides with the actual starting control law of the turbojet engine

and the model is of good engineering value.
