| 摘 要： | 所描述的轨控发动机采用同轴线对开双喷管结构设计,通过对不同工况、不同间隙条件下轨控发动机的流场进行数值模拟,得到了间隙对发动机燃烧室压强、推力等性能参数的影响规律。研究结果表明,当轨控发动机的转子配合间隙不断减小时,推力调节室总压随之不断增大,质量流率不断减小,发动机的推力调节特性变优。

| Abstract: | Different flow fields of the orbit-control motor with double opposite nozzle in different condition or in different fit clearances were numerically simulated and effect of fit clearances on orbit-control motor performance parameters was detected.Results show that when the clearance between motor and control chamber gets closer,total pressure of thrust chamber is higher;mass flow rate is lower and thrust of orbit-control motor is improved. |
