微涡喷发动机离心甩油盘环形折流燃烧室的设计与实验研究

The Design and Study of the Annular Combustion Chamber with Centrifugal Fuel Injection

微涡喷发动机是低成本的结构简单的燃气涡轮动力装置,特别适合于推动巡航导弹、(雷达)假目标、轻型直升机、无人侦察机和航空靶机。离心甩油盘环形折流燃烧室由于具有燃油雾化质量好,轴向长度短,高空性能好等优点,很适合作为微涡喷发动机动力装置的燃烧室。本文主要研究了离心甩油盘环形折流燃烧室的气动热力学参数和几何参数的设计,并通过实验研究验证参数设计的合理性。

For most micro-turbojet layouts, the annular combustion chamber is one of the best combustion system. It is the lightest, least expensive and most efficient combustion system arrangement in terms of utilization of the specified engine volume. In this paper, the design and study of the annular combustion chamber with centrifugal fuel injection are presented.
