PL9874B1 - Projectile that produces smoke. - Google Patents

Description

The present invention relates to a projectile designed to produce dense smoke. The invention resides in that metal chlorides such as tin, titanium, antimony, aluminum and the like are used to fill such a projectile; from chloride, hydrolysis produces metal hydrates in the form of particles so fine that they form dense, light-impermeable smoke that remains in the air for a long time. To facilitate hydrolysis and allow it in dry places, he adds ammonium salts, which decompose into ammonia and water, make it possible to hydrolyze metal chlorides under any conditions. The direct mixing of the above-mentioned bodies with any ammonium salt and explosive material also has the advantage that the explosion is milder, so it does not spray chlorides that produce too much smoke, which makes the smoke dense and hydrolyzes better. The water vapor generated at the time of the explosion significantly lowers the temperature of the explosion, so that the smoke produced is heavy and stays long above the ground. The explosive material and ammonium salt mix with each other in a highly powdered state and are charged to bullet shells in the form of pressed molds, so that the salt mixture does not delay the explosion too much. In some cases, it is necessary to separate the explosive from the ammonium salt, which is achieved by impregnating with paraffin, or charging them in separate packets, wrapped in a tin; in other cases, the explosive may be mixed directly with the ammonium salts. The figure shows an example of an embodiment of a projectile in accordance with the invention. The sheath 2 is screwed into the bomb 1 (Fig. 1) so that a space 3 is formed between the sheath and the bullet wall, which can be filled with a liquid material that produces smoke. For this purpose, the projectile has a hole with a plug 4. The threads of the connection are tin or lead coated so that the closure is tight; during twisting, the vagina and the projectile are heated. The explosive material and the ammonium salt are in the sheath 2. The explosion is caused by a detonation flap 5 attached to the fuse 6. The charge of the vagina 2 can be made freely, so e.g. in the form of thin, pressed plates, which, if necessary, Maybe the paraffin in which they are immersed could be insulated (Fig. 2). In order for the explosion to occur with a uniform force throughout the load, the ammonium salt plates are punched and the lines 7 formed therein are filled with explosive material (FIG. 2). PL PL

Claims (6)

1. Patent claims, 1. A smoke-producing projectile, the significant point that a hermetically sealed scabbard is placed in its hull of quite considerable dimensions, so that there is a free space inside which fills with the smoke-producing material during when the vagina is filled with a mixture of explosive material and compounds whose chemical decomposition facilitates the hydrolysis of the material that produces smoke. 2. A projectile according to claim 1 ', characterized by the fact that hydrolysable tin, titanium, antimony, aluminum or the like chlorides or the like are used as the smoke-producing mixture, and various ammonium salts, the decomposition of which are used as hydrolysable compounds for ammonia and water is facilitated by mixing them with a suitable explosive (detonated with detonate). 3. A bullet according to claim 1 and 2, the significant point that compounds which, when chemically decomposed, facilitate hydrolysis and constitute the main component of the charge that fills the internal vagina of a bullet, are landed in the form of small lumps, grains, prisms or the like, in such a way that the appropriate explosive material fills the free spaces between these particles, in order to achieve the largest contact surfaces between the particles of the explosive land and the materials whose decomposition, due to the explosion, is to aid the hydrolysis. 4. A projectile according to claim 1-3, the significant point that the particles of the material, the decomposition of which supports the hydrolysis, are properly insulated from each other, either by impregnating with paraffin or by using the material in the form of pouches, wrapped for insulation with staniol or paraffin paper. 5. Projectile according to claim 1-4, a significant area, with the individual ammonium salt nuggets, the decomposition of which promotes hydrolysis, are made into a plate shape or the like by pressing, and are isolated from one another by means of paraffin or other insulating material. 6. A bullet as in claim 1-5, the significant point that the lumps, the chemical decomposition of which supports the hydrolysis, are provided with holes filled with an explosive material, whereby a large contact surface between the mentioned materials is obtained. v Akciova Spolecnost drive Skodovy Zavody v Plzni.
