Computational Design of the Cavity in the Enhanced Hypervelocity Launcher

  • 摘要: 使用多介质流体高精度计算程序(MFPPM, Multi-Fluid Piecewise Parabolic Method)对汇聚型超高速发射装置的发射腔进行了计算设计。根据发射腔角度的不同,提出了3种改进的发射腔结构,计算研究了发射腔角度和TPX厚度对二级飞片速度、速度差异和击靶位置平面性的影响。计算结果表明:在3种TPX厚度以及击靶位置下,使用第2种发射腔结构发射出的二级飞片的平面性最好、速度最高、汇聚效果最强,但平面性范围最小,且二级飞片自由面速度差异变大,其平面性难以得到维持。
