Abstract
A forwardly concave insert for a hollow charge of an armor-piercing missile or projectile has an inner peripheral wall with linear generatrices and an outer peripheral wall with at least partly curved generatrices diverging from the inner wall surface to an annular zone of maximum wall thickness at more than half the distance from the point of the cone to its base, the outer generatrices having centers of curvature lying beyond the cone axis on radii which are perpendicular to the inner wall surface at that annular zone. The arcuately curved sections of these outer generatrices merge tangentially into substantially straight-line sections converging at the cone axis into the aforementioned point.
Claims8
In an armor-piercing projectile having a casing with a substantially cylindrical wall portion, an insert of generally hollow-frustoconical shape in said casing with a rearwardly facing point on the axis of said wall portion and a forwardly facing base adjoining said wall portion, and a charge behind said insert in said casing,
- the improvement wherein said insert has an inner peripheral surface of conical shape with an obtuse vertex angle and straight-line generatrices and an outer peripheral surface of generally conical shape whose axial distance from said inner surface progressively from a minimum value at said point to a maximum value in a predetermined annular zone and thereafter decreases to a value greater than said minimum value at said base.
