Abstract
According to the detonation wave collision theory, initiation from two ends of charge, the liner will close to the middle to form high velocity penetrator. To achieve better closed effect, the influence of axis curvature radius on a single Annular MEFP was studied. Axis curvature radius influence little collision pressure, but is the important factor affecting the formation. The results showed the presence of axis curvature radius can all reach the closure effect, but different greatly. The velocity and mass of penetrator increase as decrease of axis curvature radius, but it forms easily to be rod jet, when the radius is too small. The penetrator mass have bigger loss as increase of axis curvature radius.
