ABSTRACT
The penetrator will penetrate the concrete plates by using kinetic energy. In order to make the longrod penetrator to have a better penetrating ability, the ratio of the length and diameter should be increased properly. In addition, to make the tungsten alloy long-rod penetrator penetrate the concrete plates more easily when it has big oblique angle and has a better damage effect, the penetrator should have an acurrate warhead. In most cases, ovoid bullet, cylindrical bullet and flat bullet are very common. The ovoid bullet has better penetrating ability compared with cylindrical bullet and flat bullet. However, when the oblique angle is big, ovoid bullet will ricochet more easily. Flat bullet is in the middle among the three. Cylindrical bullet has the worst penetrating ability, but it does not ricochet so easily compared with ovoid and flat bullets. According to the characteristics of concrete plates, the penetrator in this article is flat bullet.
