PL26191B1 - A projectile that does not produce debris. - Google Patents

Description

The present invention relates to a tracer, smoke or quasi-firing projectile which is reusable and does not exhibit any debris or projecting plugs or other obliterating devices when operating.

An embodiment of the invention is shown in the attached drawing. Fig. 1 shows a longitudinal section of the projectile, and Fig. 2 shows the valve in the open position.

At the bottom of the shell 1 of the shell 1, intended for mortars and provided with saw blades, there is a cavity 2 (Fig. 2) which is closed by a valve 3 which is kept closed by clamping it or by any other suitable means, e.g. a spigot, putty, springs, etc., the valve should not move backwards under the influence of impacts during transport and handling, but should move at the appropriate moment after ignition of the charge of the internal projectile, such as this is explained further.

The embodiment 2 in the present embodiment has a ring-shaped cap 3a which prevents the wave from penetrating into the shell of the projectile, especially under the influence of the pressure of the gunpowder gases upon firing. 96 Ai. The throat in the shell is best served by thick copo-lacquer or some other suitable agent.

Part 4 of the exclusion 2 outside the valve 3 is connected to the outside air by one or more openings 5 with a variable slope.

A tail 6 equipped with saw blades is screwed into the bottom of the shell.

In the smoke mass (composed, for example, of hexachloroethane and calcium silicide, possibly with the addition of a dye), which is loaded, we will make a fescal 9, in which the incendiary mass is placed (e.g. a mixture of hexachloroethane and aluminum).

The channel 9 connects the valve 3 to the mat 10, preferably containing mercury fulminate. If there is a need to place in the interior of the shell an equalizing weight, with a positive hp. of silica, tar or other suitable fciaterial, it is preferably positioned on the inside circumference of the projectile at the point of greatest diameter. The head 12 is screwed in the front of the shell, into which the fuse 13 is screwed into it.

The missile operates as follows.

"At the moment of firing, the protrusion of the ring 3" prevents the valve 3 from moving into the interior of the projectile and the effect of the pressure of the powder gases. As soon as the projectile hits an obstacle, the fuse 13 ignites the excitation flame 10. The heat generated by the explosion of this flap causes the six Chlorofeem to a temperature higher than its boiling point (f810), with the formation of chloride of aluminum (boiling point 183 °) which transmits ignition along the entire channel 9. The pressure generated opens valve 3 which is thrown back into the position shown in FIG. 2.

The combustion of the smoke mass 8, ignited by the mass 9, and the escape of the smoke through the openers 5, takes place at a very high speed.

Instead of placing the ignition mass indirectly in the mass 8, it is also possible to place the ignition mass in a combustion tube (cardboard, celluloid, etc.) or in a non-combustible but perforated tube. This mass can moreover be placed in a channel or a tube placed eccentrically in the projectile, and this channel may have any shape, e.g. screw, broken, etc.

You can use more channels again.

In order to use this projectile as a tracer, it is sufficient to ignite the charge at the appropriate moment with a suitable detonator.

You can likewise add a 'draftraiae $ db flying' option to the smoke load in order to receive an offensive or defensive projectile or to test breathing apparatus to kill parasites, etc.

A projectile may only be loaded with smoke, incendiary or extinguishing substances and, in general, may be used in all cases involving the extension of solid, liquid or gaseous materials to a distance without ejecting debris.

The exit opening or openings may, depending on the intended use of the projectile, open at any tangles of the external surface.

The device according to the invention is suitable for projectiles of all kinds intended for smooth or rifled weapons !, for granals of all kinds, "air bombs, etc."

Of course, the invention has been described above and shown in the drawing by way of example only, since changes can be made without excluding its serious frame. - 2 - Ztts tr zasettfiii p «.teiltowe, 1. A projectile that gives off fragments, the bottom of which is a twisted tail, provided with ribbons, characterized by the fact that there is a cavity at its bottom, connected with the atmosphere and interior of the the inside of the projectile is covered by a valve, e.g. in the form of a pressed-in cork wen, which, after hitting an obstacle, is pushed back, revealing holes connecting with the atmosphere, but does not fall out into the outside, but rests on a curled tail . 2, The projectile according to claim 1, which has a smoke charge inside and is provided with a head shock fuse, characterized in that the flame is transferred from the impact fuse to the smoke charge of the projectile via an ignition mass (9) located in a channel connecting the fuse with the hole in the bottom of the projectile, covered with a stopper. 3. A projectile according to claim 1 and 2, having the shape of a drop, characterized in that the internal charge for equalizing the weight of the projectile surrounds its main landing and is located at the largest diameter inside the projectile.
