| 摘 要： | 目的针对一种基于MEMS技术的固体微推进器结构,分析比较瞬态燃烧效应和推进器喉部尺寸对推进性能的影响。方法选择dp/dt燃速瞬态燃烧模型对推进器工作过程进行三维数值仿真。结果在同一燃速模型中随着喉部面积的增大,压强有显著地减小,而推力有明显的增大。结论瞬态燃烧效应不是影响固体微推进器工作性能的主要因素。

| Abstract: | Aim To analyze and compare the effects of transient combustion and propulsion throat size for solid micro-propulsion structure based on MEMS technology.Methods The dp/dt transient burning speed combustion model was chasen,its working process was simulated by three-dimensional N-S equations.Results As the throat area increases at the same burning rate model,the pressure significantly decreases,with significantly increasing thrust.Conclusion The transient burning speed combustion is not the primary effect on the ballistic characteristics of the solid micro-thruster. |
