Study on Novel Penetrator Impacting Semi-infinite Target Perpendicularly

摘要

Some experiments are carded out on two kinds of novel penetrators with different section shape, triangle and quadrangle, impacting semi-infinite target perpendicularly with velocity of 1400m/s to 1900m/s and L/D of 20 and 15. In addition, circle section penetrator with the same mass and length is tested and the three results are compared one another. By contrast, it shows the status of the impact velocity of 1700m/s being very important.While the velocity is lower than 1700m/s, the penetrating power of the three penetrators with different section shape almost equal. But once it exceeds 1700m/s, the penetrating power of those three kinds of penetrators differ widely. The triangle rod penetrates the most deep,the second the quadrangle, and the last the circle. Based on the experiments, some theory modelling and numerical simulation are made and compared with the foregoing experimental outcome, and they consist with one another.
