某型涡轴发动机地面低温起动技术研究

Investigation on Ground-Start of a Turboshaft Engine in Low Temperature

分别从不加温直接起动、数控系统控制规律更改、加温后起动等各方面对某型全数控涡轴发动机在高寒机场的地面低温起动试验进行分析研究,最终总结出该型发动机的地面低温起动规律。结果表明:延长起动机带转时间,并对发动机进行适时加温,可使发动机低温起动成功。

The ground-start of turboshaft with full authority digital electric control system（FADEC） in low temperature test was analyzed on aspects of immediate start with no calefaction,FADEC controlling law updatinog,and start after heat up.The engine ground-start law in low temperature was summarized.The results indicate that prolonging the work time of starter and proper heating up on the engine will achieve the engine starting in low temperature.
