| 摘 要： | 本文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。

| Abstract: | This paper puts forward a design method for fuel supply control law of ground start for turbofan engine. 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. |
