低温环境对某型涡轴发动机起动性能影响分析研究

Analysis of the influence of low temperature on starting performance of the turbo-shaft engine

针对某型涡轴发动机在0℃左右的低温环境中出现的带转时间过长问题,分析了低温环境对其起动性能的影响,发现了造成带转时间长的原因,并提出了改进低温起动措施。开车结果表明该措施有效,为该型发动机在低温条件下起动设计提供了参考。

Aiming at the problem of long - term driving rotation of turbo - shaft engine under low temperature in the starting process ,the influences of low temperature on starting performance of the engine were analyzed. And the reason of long - term driving rotation was found, the measures to improve the starting under low temperature were proposed. Driving results showed that the measures are effective. These can provide the references for stating design of turbo - shaft engine under low temperature.
