摘要
报道了再生式液体发射药火炮 (RLPG)点火及模拟工质冷态喷射过程的实验结果 ,定量测试了燃烧室、贮液室压力曲线。实验表明 ,采用液体阻尼可以有效减弱点火过程中的压力振荡。针对点火喷射过程建立了数学物理模型 ,并进行了相应数值模拟 ,计算值和实验数据吻合较好。
Ignition and cold injection processes using simulation medium in regenerative liquid propellant gun were investigated experimentally. Pressure time curves in reservoirs and combustion chambers were measured.The results show that pressure oscillation during ignition was suppressed by using liquid damper.A physical and mathematical model for the process is suggested,numerical simulation was also presented here.The calculated results are in good accord with the experimental data.These results have instructive meaning and practical value for analyzing interior ballistic cycle of RLPG.
