Explosive projectile, particularly artillery explosive projectile, has projectile axis, projectile casing, projectile cavity formed with projectile inner wall that has cylinder with cylinder longitudinal axis in section

摘要

The explosive projectile (1) has a projectile axis (2), a projectile casing (3), a projectile cavity (4) formed with a projectile inner wall (5). The projectile inner wall has a cylinder with a cylinder longitudinal axis in a section (6) and forms a cylinder top surface (7), where the cylinder longitudinal axis is located in the projectile axis. The cylinder top surface has a rough region (8) that enables interlocking contact of the projectile inner wall for the explosive charge. The rough region is a coupling or a cross coupling or a helical groove.
