Abstract

In the future war, “gold stick” space-based kinetic energy weapons plays an important role in attacking deep underground targets, and it is also significant for safeguarding national interests and territorial integrity. First, considering the impact of outside temperature, pressure, altitude, atmospheric density, flight speed and other factors on the air friction, this paper analyzed that the “god stick” kinetic energy projectile’s speed would arrive 3401.7m/s. Currently, limited by experimental techniques and methods, only Gold achieved a few groups of experimental datas,of high-speed kinetic energy projectile penetrating into concrete targets, and the highest penetration velocity is less than 2km / s, such as "God stick" ultra-high-speed kinetic energy projectile penetrating into concrete targets’ experimental study is still blank. Therefore, the article completed theory and numerical simulation analysis of “god stick” penetrating a semi-infinite concrete targets. The result shows that: the final penetration depth obtained by numerical simulation(18.9m) agrees well with the theoretical results(17.3m), the finally crater diameter of concrete targets reaches 7.333 times of the diameter of bomb; comparing with the continue declined velocity of rigid projectile, during the process of “god stick” hypervelocity penetration , transient high pressure phase has quickly dropped velocity of warhead, high kinetic energy loss rate, small corresponding penetration depth, stable penetration stage has stable warhead speed, stable rod length maceration, basically unchanged kinetic energy loss rate, and linearly increasing depth of penetration. When the impact speed of projectile arrives large enough, the final penetration depth is mainly affected by the density of projectile and target materials, not by the strength. So the high-density stratification protective structure has great advantages in anti-hypervelocity penetration areas.
