The rotational motion of finned shaped-charge liners is studied. It is 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 in the liner cross-section. The proposed method can be used to estimate the average angular velocity of the jet with consideration of the size of the finned shaped-charge liner and the properties of its material. It is shown that the results are consistent with available experimental data.
