Smoke-producing compositions are disclosed that combine the low toxicity of an organic acid smoke and the high obscuration effect of a red phosphorus (RP) smoke. Phosphoric acid produced by RP is neutralized by an acid scavenger added to at least one of the RP or organic acid smoke formulations. To prevent chemical reaction between ingredients of the two smoke-producing formulations, they are separated in the apparatus of the present invention such that only the resulting smokes mix. Very small amount of a RP smoke formulation increases the obscuration index of organic acid smokes comparable to conventional hygroscopic chloride (HC) smokes.
Improvements applied to the case of a smoke bomb. This invention relates to the envelope of a smoke bomb case. It consists, on the one hand, of a traditional wall (1), resistant to the pressure of the smoke bomb constituents (4) when it is the object of the exothermic reaction of the smoke bomb powder, once it has been initiated by an adequate technique. It comprises, on the other hand, at least one area of reduced resistance (3), formed by a relatively fine layer, the said area being covered by a cover (2) of a resistance comparable to the remainder of the traditional wall (1), and which is pierced by a large number of holes (6, 7, and 8). It is characterized by the fact that each hole (6 or 7 or 8) of said cover (2) has a warped form.
A smoke generating composition including at least one smoke generating material and an effective amount of a polymerized monosaccharide or disaccharide as a binder. The polymerized monosaccharide or disaccharide serves the dual purpose of being both a binder and a fuel to provide a more efficient and safer smoke generating composition.
A mortar cartridge generates effective white or colored smoke obscuration with reduced adverse environmental impact and collateral damage, and provides an improved drag assembly that reduces drift during projectile descent and improves targeting.
