Abstract Keywords
The purpose of this work was to analyze the fluted liners axial
rotation by numerical and analytical methods. The study re-
vealed that pressure at the border between the liner and the
products of detonation depends on the pitch angle of the
oblique shock wave front. This is the cause for the rotation.
According to the pressure dependence on the angle between
the shock wave and the liner surface, we estimated the angular
velocity of the shaped charge jet. Influence of the liner material
properties and cross-section dimensions on jet angular velocity
also was evaluated. The results are in good agreement with
known experimental data
