A projectile is described which consists of a contact head 1 and a screen material canister 3 which is made of aluminium, attached thereto by bolts 45 and, optionally closed with a cover 5. Contact rings 9 are arranged on an outer casing of the contact head and are connected via firing leads to a primer capsule 17 which is located in the contact head in a centrally disposed box-shaped charge chamber 13 having a substantially gas-tight screw cover 47 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 107 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 75 having a charge 35 for igniting the screen material 83, 127, 125 and fragmenting a casing of the canister, or through an expelling charge chamber (37) Figure 5 (not shown) containing an expelling charge (39) for expulsion of the screen material at rupture of the cover on the head of the canister. The screw cover 47 is formed at its edge with a screw thread 49 and may be formed at least in its central region with an abutment 51 for a spacer of a cup discharger, the parts of the cover between the edge and the abutment being formed with weakened areas 57 for the escape of propellant gases. The screen material may consist of thin smoke-producing combustible lamellae 83, which may comprise a carrier material carrying a slow-burning combustion layer, and optionally smoke-producing pellets 125 embedded in smoke-producing granulate 127, or packages of chaff (73) Figure 6 (not shown). <IMAGE> |
