针对临近空间特殊的飞行环境和流场特性,以面对称的子母弹为具体研究对象,采用CFD仿真计算的方法,得到了腹抛分离发射方式下分离速度、高度、子弹气动力与姿态角之间的关系,在研究和分析多者之间变化规律和趋势的基础上,提出了适用于临近空间腹抛分离发射的分离方案,这为今后开展该领域分离发射技术的研究和临近空间气动流场的仿真分析奠定了基础。
Aiming at the special flight environment and the characteristics of the flow field in the near space, the symmetric submunition bomb is taken as the specific research object. The velocity, height, the aerodynamic force and the attitude angle of the bullet are obtained by CFD simulation. On the basis of studying and analyzing the changing rules and trends among many people, this paper proposes a separation scheme applicable to the separation and launch of the adjacent space in the vicinity of the space, which is of great significance for the future research on the separation launch technology in this field and the near spatial aerodynamic flow Field simulation analysis laid the foundation.
