Abstract

A projectile is described which consists of a contact head and a screen material canister which may be made of aluminum, attached thereto by bolts and, optionally closed with a cover. Contact rings are arranged on an outer casing of the contact head and are connected via firing leads to a primer capsule which is located in the contact head in a centrally disposed box-shaped charge chamber having a substantially gas-tight screw cover at its base and substantially gas-tight ports for the firing leads, the ports being sealed with a sealing agent. A delayed action fuse assembly is arranged in the head section of the contact head or in the base of the screen material canister and connects the charge chamber and the canister, the assembly being in communication with the canister either through an igniter-destructor unit having a charge for igniting the screen material and fragmenting a casing of the canister, or through an expelling charge chamber containing an expelling charge for expulsion of the screen material at rupture of the cover on the head of the canister. The screw cover is formed at its edge with a screw thread and is formed at least in its central region with an abutment for…
