The invention relates to a sub-ammunition object for vapor generation for a spinstabilized carrier projectile with axial sub-ammunition discharge, consisting of a stackable, flat, disk-shaped, stamped part of identical caliber, which, at a height/width ratio of about 1:1.5 to 1:5, contains red phosphorus as the primary active substance and is designed to retain its structural and form stability during firing, discharge, and stacking as a result of fibers embedded in the active substance and/or a shell, with the combustion time being chemically and/or physically adjustable through the height, compression pressure and/or composition of the active substance. It is preferred that the active substance be located in a container with at least one blower aperture and one oxygen donor as the energy supply needed for combustion of the red phosphorus in the container.

Sub-ammunition object for vapor generation

The invention is directed to an ammunition casing made of a composite fiber material, which comprises fiber material and a bonding agent, is at least partially flammable and has a high strength. The ammunition casing is particularly useful when surrounding a smoke screen unit, and the combustion reaction products of the composite fiber material form soot particles, preferably of hydrocarbon C.sub.X H.sub.Y, which will contribute to the smoke screen effect of the smoke screen unit during combustion.

Ammunition casing of composite fiber material

A smoke screen shell is provided having a rapidly burning decoy charge that generates a spontaneous fog and a slowly burning camouflage charge that generates a lasting fog. The decoy charge and camouflage charge are fired from a canister sleeve by an ejection charge. Upon firing, pressure from the ejection charge is communicated through a channel to a relief chamber positioned between the decoy charge and the camouflage charge. This results in an accelleration difference, causing a separation and slightly different trajectories, the decoy component accelerating at a higher rate. The decoy charge takes effect in the air prior to the camouflage charge. The collocation of the spontaneous fog and of the lasting fog essentially occurs in the target. The decoy charge and the camouflage charge land within a proximity at a target area such that a collocation occurs between the spontaneous fog and of the delayed lasting fog. The ignition and relief chambers, the channel therebetween, the charges, etc. are dimensioned and configured to assure the desired proximal collocation without a mechanical connection between the camouflage charge and the decoy charge.
