摘要

为提升头部进气固体火箭超燃冲压发动机的燃烧性能,采用数值模拟方法研究了富燃燃气喷孔结构形式对发动机燃烧性能的影响。研究结果表明相比传统的圆形截面喷孔结构,采用椭圆截面喷孔结构条件下富燃燃气与空气的掺混更加充分,化学反应速率更高,具有更高的推力及比冲增益。随着椭圆截面喷孔长半轴与短半轴比值的增大,补燃室燃烧性能更加优异,建议工程上采用椭圆截面喷孔。

Abstract

In order to improve the combustion performance of head intake solid rocket scramjet, the effect of rich fuel gas nozzle structure on the engine combustion performance was researched by using numerical simulation. The result showed that compared with the traditional round section nozzle structure, the elliptical section nozzle structure has more sufficient mixing of rich fuel gas and air, higher chemical reaction rate, higher thrust, and specific impulse gain. With the ratio increase of long half axis to short half axis of elliptical section nozzle, the combustion performance of secondary combustion chamber is better. It is recommended to use elliptical section nozzle in engineering.
