摘　　要：为了提高动态条件下聚能射流的稳定性和破甲能力，深入了解气动力和靶板材料对射流稳定性的影响，通过对射流形成后至碰靶前的理论分析和射流微元的参量计算，探讨了空气动力和靶板材料对射流稳定性的影响，得出：气动力、靶板材料的特性等对射流的稳定性有重要影响；径向运动的发展是射流发散的主要原因；射流的延伸断裂失稳过程是空气动力作用和射流靶板内应力状态不断变化的过程，也是能量不断消耗转化的过程。控制气动力和靶板材料特性的影响，可以提高射流的稳定性，增强破甲能力。For improving the stability and the ability of breaking amour of the shaped charge jet under dynamic condition, the influence of aerodynamic and target material on the stability of jet is deeply studied. Through the theoretical analysis of jet after forming and before meeting the target and the parameter calculation of tiny element of jet, the influence of aerodynamic and target material on stability of jet is discussed. And the conclusion is that the properties of aerodynamic and target material have very important influences on the stability of jet; the development of radial movement is the main reason of jet scattering; the extending and breaking process of jet is the course of aerodynamic effects and continuous changing of stress inside the jet target, as well as the course of energy consumption and transformation. The stability of jet and the ability of breaking armour can be improved by controlling the influence of properties of aerodynamic and target material.
