| 摘 要： | 为了得到航弹母弹飞行稳定性及尾部流场特性,通过模拟试验和数值计算进行了研究.试验和模拟结果均表明该母弹飞行稳定,且两结果吻合较好.另外,采用数值计算对尾部流场进行了分析,得到了尾部压力分布特性,表明弹尾部存在涡流区,该区范围和流速随弹飞行速度的增加而增大.

| Abstract: | Flight stability and rear flow fields of the cargo projectile were studied by simulation test and numerical computation.The cargo projectile can fly stably and the results of simulation test agree well with numerical computation.In addition,the rear pressure distribution was also obtained by numerical computation,showing that there are eddy-current zones at the bomb rear,which will increase with the flight speed. |

| Keywords: | simulation test flight stability rear flow fields eddy-current zone |
