In order to deduce the engine control law during the helicopter autorotation, simulation was made to demonstrate the transient process of the engine when entering the helicopter autorotation condition using normal control law. Based on the existing control law, an improved law was brought forward by magnifying the differential gain of collective pitch "anticipator" and broadening the deceleration limitation.

为确定直升机自转下滑训练过程发动机的控制规律，分析了采用正常控制规律进入自转状态时涡轴发动机的变化过程，提出了在现有控制规律基础上增强动力涡轮转速控制模块中总矩"提前器"作用和适当放宽速率限制值的控制对策。

The simulation results show that the improved control law can satisfy the requirement of the helicopter, thus attaining an effective way for the control of the engine during the helicopter autorotation.
