Abstract (en)

[origin: EP0773424A1] The explosive charge cover (4), especially for a sub-munition ejected from a carrier shell, is fitted onto a support (5) with a cylindrical projection (5a) adjusted to the inner diameter of the charge casing, the support being fixed to the casing by connectors which ensure its axial retention. The support (5) is ring-shaped, conical or in the form of a dome applied to the explosive charge (3) and made with a recess to receive the cover, the cover being made from tantalum and the dome of aluminium alloy. Where the support is in the form of a ring it can have concentric flexible tongues.
