Experimental study on the penetration performance of truncated-ogive nose projectile

The paper discusses experimental results of launching truncated-ogive-nose earth penetrating weapon into concrete targets. The motion process of projectile is studied using the high-speed recording photographs of the reduce scale earth penetrating weapon penetrating process and test results. Velocity curves and resistance histories of truncated-ogive-nose earth penetrating weapon into concrete targets are recorded. At the same time, using reduce scale theory, computation method and analysis results of the penetrability are presented for standard earth penetrating weapon for concrete targets.
