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。
The rail-controlled engine described in this paper adopts the double-nozzle coaxial structure design. Through the numerical simulation of the flow field of orbit control engine under different working conditions and different clearance conditions, the performance of the gap on the pressure and thrust of the combustion chamber of the engine is obtained The influence law of the parameter. The results show that when the orbital control engine rotor with the gap continues to decrease, the total pressure of the thrust control chamber increases with the mass flow rate decreases, the thrust control characteristics of the engine become better.
