Rotational Motion of Fluted Shaped-Charge Liners

Resumo

The rotational motion of fluted shaped-charge liners has been studied. It has been shown that the main factors affecting the rotation of a shaped-charge jet are the position of the jet-forming layer and the distribution of the circumferential velocity over the liner cross-section. The proposed method can be used to estimate the average angular velocity of a jet with consideration of the dimensions of the fluted shaped-charge liner and the properties of its material. It is shown that the results are consistent with available experimental data.
