To improve the penetration efficiency of long-rod penetrator, in view of long-rod penetrator vertically penetrating semi-infinite target, key factors affecting the penetration depth were analyzed, and effect mechanism of the factors on penetration depth was studied with empirical formula deduced from experiments and numerical simulations. The results show that if initial kinetic energy of the long-rod penetrator is constant, the optimal values of aspect ratio, incident velocity, rotation velocity exist, when the maximum depth is obtained, and as the values of these factors change, the penetration depth would decline. How to obtain and optimize these values was provided.
