摘要: |
针对多级导弹级间热分离这一复杂环境条件,用数值模拟的方法对级间段流场进行了预示。计算采用Godunov有限体积格式,对非定常轴对称欧拉方程进行求解。计算结果为级间分离段和发动机热防护的设计提供了理论依据。 |

Abstract: |
The thermal stage separation condition of multi stage missile is very complex.The flow field for thermal stage separation part is predicted with numerical simulation in this paper.The Godunov finite volume method is used to solve the unsteady axisymmetric Eluer equations.The results can provide basis for the design of the thermal protection of motor case the stage separation part |
