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%提出了一种涡扇发动机地面起动供油规律的设计方法,通过引入转速上升速率作为控制参数,设计转速上升速率给定控制规律,采用闭环控制适应性调整起动供油量,在很大程度上降低起动过程对供油精度的敏感度,并应用于某型航空涡扇发动机地面起动,取得了良好的验证效果.
