Abstract:
To analyze the influence of target thickness on the lateral effect of PELE(Penetrator with enhanced lateral effect),by changing target board thickness,simulations and experimentations are carried out on PELE impacting target perpendicularly in the same speed.The results show that,after drilling through a target,the residual axial velocity of the penetrator tends to slow down as the target thickness increases,while the biggest radial velocity of debris augments first and diminishes gradually.When the target thickness goes up to some extent,the projectile loses the most of its energy during perforating and the lateral effect weakens remarkably.For a given system,in which PELE and target are unaltered,there is optimal thickness of the target for PELE exerting its lateral effect.
