摘　　要：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。A design method for fuel supply control law of ground start for tt/rbofan 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.
