摘　　要：本文研究航空发动机空中因富油问题导致起动困难,在分析起动供油的基础上,设计了高空修正模块来补偿飞行高度对供油特性的影响。并通过模拟试验进行了比较和分析。结果表明方案可行,能够解决发动机空中起动时的富油状态问题。In this paper, we study the aircraft engine air starting difficulty caused by rich oil problem, based on the analysis of starting fuel supply, designs the high altitude correction module to compensate the influence of altitude on fuel supply characteristics. And taking comparison and analysis through the simulation test, results show that the scheme is feasible, and can solve the problem of oil-rich state of engine airstart.
