摘要: |
采用准一维非定常数值模型,对某小型固体发动机尾部点火瞬态过程进行性能预示;以预示结果为基础,对尾部点火性能主要影响因素进行了参数研究。研究结果可为尾部点火器和喷管堵盖的点火匹配性设计提供有益指导。 |

Abstract: |
With a quasi 1-D unsteady flow model, a numerical simulation is completed to analyze the ignition transient in a small solid rocket motor activated by a rear igniter. Based on the simulation results, a detailed parameter analysis is performed for some key factors which may heavily affect the performance of ignition transient. The results can provide a useful guide for the matching design between the rear igniter and the nozzle seal. |
