固体火箭发动机结构轴向振动对内弹道影响

The Influence of Structural Axial Vibration on Solid Rocket Internal Ballistics

文中研究了固体发动机结构的轴向振动对燃烧室内弹道性能的影响。在一维非定常内弹道方程中,考虑了结构轴向振动及侵蚀燃烧的影响。在给定强迫振动模型的情况下对不同频率的轴向振动的内弹道方程进行了数值模拟。结果表明发动机轴向振动对燃烧室内弹道有着显著的影响。

The influence of structure axial vibration on the internal ballistics of solid rocket motor was investigated. With considering tbe effect of structural axial vibration and erosive burning, the one-dimensional conservation equations were used to compute internal ballistics of solid rocket motor. Given the forced vibration model, the internal ballistics that considered effect of different frequency axial vibration were modelled. The results proved that axial vibration of the motor have obvious influence on internal ballistics of solid rocket motor.
