Research on the Fuel Supply Control Law of Ground Start for Turbofan Engine Based on Speed Rising Ratio

A design method for fuel supply control law of ground start for turbofan engine is put forward.The method reduced the sensitivity of fuel supply precision by applying the speed rising ratio as a control parameter in ground start.The control law is given by designing speed rising ratio in closed-loop system,which adjusts fuel supply adaptively.It obtained a good verification by applying a certain type of ground start for turbofan engine
