摘要
本文综述了通过实验室试验和弹丸飞行试验,描述一种可缩短圆柱形腔内装填液体旋转加速时间的技术.阐述了圆柱形腔内端壁区布满高渗透性介质时,大大加强控制液体旋转加速过程的二次流动的机理,从而达到缩短旋转加速期提高稳定性的目的。
This paper summarized the techniguc by which the spin-up in the cylin-der was reduced that was evaluated via the laboratory tests and flight tests of theprojectiles. This is a principle that permeability medium strongly controls the secondflow of fluid spin-up process, to achieve the reduction of spin-up period and ad-vance stability, when the region located at the end wall of a cylinder is fulldustributed permeability medium.
