Abstract

In order to study the critical penetration velocity and aftereffect of small-caliber cluster tungsten-fiber penetrator with enhanced lateral efficiency(PELE)penetrating rolled homogeneous armor(RHA)with 10 mm thickness,the theoretical calculation of cluster tungsten-fiber PELE of 23 mm diameter penetrating RHA with 10 mm thickness was carried out by using the theoretical model of PELE vertically penetrating thin metallic plate.The penetration experiment by using ballistic gun with 23 mm caliber was conducted.The results show that the critical penetration velocity is 623.7 m/s,and the PELE can produce good aftereffect after penetrating RHA with 10 mm thickness while the impact velocity is more than 685.2 m/s.The experimental result accords with the theoretical calculation result.
