The Numerical Simulation Investigation on Penetration Capability of New Nose Shape Projectile Penetrating into Concrete Target
Abstract
Based on the new structure earth penetrating warhead (EPW) validated by MBDA, the new nose shape projectiles with multi-teeth shape were established in this paper. Numerical simulations were conducted on the penetration capability of projectiles with tooth and those with general nose shape penetrating into concrete. The effects of tooth nose shape parameters tooth height(TH) and nose pole diameter(D) on penetration capability of projectiles is discussed. The approaches were brought forward for enhancement of penetration of EPW with tooth nose shape by increasing TH and decreasing D under a certain extension, and achieved a reasonable combination.
