固连接异形侵彻体侵彻威力研究

采用对半无限靶侵彻深度的测量方法进行固连接异形侵彻体的侵彻威力实验，并与同质量、直径和异形侵彻体管外径也相同的基准杆进行比较。结果表明：在同一速度下该异形侵彻体相对于基准杆有较大的穿深增益；管的内外径比对穿深的影响较大。建立了固连接异形侵彻体垂直侵彻半无限靶板的理论分析模型，计算和实验结果较为一致；得出了穿深增益随速度的变化规律，发现速度在1．7km／s左右时异形侵彻体相对于基准杆的优势最为明显。得出了侵彻体穿深随内外径比的变化规律，在某一范围内，穿深随着内外径比的增加而增加。

Performance of Telescopic Penetrator

Experimental study of the terminal ballistic performance of a telescopic penetrator is performed by means of DOP (depth of penetration) tests. The results show that it has much better performance than that of the baseline rod of the same mass, whose diameter is equal to that of the tubular part of the telescopic penetrator. The ratio of inner to outer radio plays an important role in DOP of the telescopic penetrator. The analytical model of the telescopic penetrator penetration into semi-infinite target is established. The analytical results accord with the experimental ones. The advantage of the telescopic penetrator vs velocity is gained and the advantage is the most obvious at about 1.7 km/s. The results also show that the DOP of the telescopic penetrator increases with the increase of the ratio of inner to outer radio at some range.
