Possibility of Increase in Penetration Depth into Soil and Rocky Targets of Composite Projectiles with the Tail Part Thrown Back During Penetration

Abstract

The possibility of increase in depth of penetration into soil and rocky targets of composite projectiles with the tail part thrown back in the course of interaction is considered. The thrown back tail ballast mass had a tubular part that acted as a ballistic barrel in which the penetrating module was placed. When the ballast mass is thrown in the direction opposite to the penetration direction, the penetrating module receives an additional impulse in the direction of its movement, which can lead to an increase in the penetration depth of the module. Based on the calculation results, the influence on the penetration depth increase of the mass ratio of the thrown back and penetrating parts of the projectile, of the ballast mass throwing back time, of the throwing pressure and of the ballast mass tubular part length determining the powder gas pressure action time is established for the targets of the type of dense soil and rock.
