Description

Technical field

BACKGROUND OF THE INVENTION The invention relates to a training target which is connected via a conduit to an external source producing a gaseous heated medium and which has a channel inside the target, into which the conduit opens, the channel being laterally limited by guide rails and the target having a plate rear wall fastened front wall of plastic material.

BACKGROUND OF THE INVENTION

Such a training target is used for training in sharp-shot shooting in daylight and at the same time poor visibility, or at night if target detection, target selection and target shooting, as well as operating the weapon system, are practiced under real conditions.

FR 2 544 067 A1 describes various possibilities for creating a training target. On the one hand, it is proposed to make a rear wall of a wooden board or a rigid metal plate and cover it with a front wall in the form of a plastic film, and on the other hand a possibility of realization according to which a training target structure is formed. they stretch over two beams that are arranged on the edge of the practice target.

The first embodiment, due to the use of solid materials, is not suitable for firing by guided flying bodies or bullets with a hollow charge, since their sharply set lighters would operate on impact and the target would be destroyed at the first hit. In addition, wood is used as a consumable here. This should be avoided with regard to the environmental burden, as wood as a natural product grows only very slowly and the wood-destroyed wooden target can no longer be used in the re-process for the production of other targets. In addition, the heating of wooden boards creates some inertia, so it is not possible to practice near-emerging and disappearing targets.

The second embodiment with fabric or foil has the disadvantage of mechanical instability under certain weather conditions, which is unfavorable both in the depiction of the target and in the handling of the target assembly. In addition, it is not ensured that the target could still be recognized even after a few hits with 120 mm bullets, since too much heated air escapes in the event of a nighttime use of torn fabric or foil material.

The fact that the target mounting frame is roughly the same as the edge of the target has proved to be a significant disadvantage when compared to similar targets. When shelling high-caliber missiles is often hit by the edge or frame, which makes the target unusable due to lack of its own stability.

SUMMARY OF THE INVENTION

SUMMARY OF THE INVENTION It is an object of the present invention to provide a training target in order to overcome these drawbacks of the prior art in such a way that handling, transportation and assembly is improved, so that the target in the area typically encountered by missiles will consist exclusively of reusable material; that with this target, a realistic representation in terms of time behavior and good recognizability, in particular surface heat distribution, is achieved even after a large number of large-caliber missile hits.

-1 CZ 286138 B6

The task is solved by a training target, which is based on the fact that the rear wall of the training target consists of a bowl made of shaped rigid plastic material, on the one hand, and has a rear wall more in the interior space between the rear wall and the front wall and on the other hand, in the region of the lower edge of the at least one wall, a horizontally arranged pipe is easily releasably fastened and connected to a gaseous medium source via an inlet and having an intermediate space between the ribs and / or notches for each intermediate space. at least one air outlet.

According to a preferred embodiment, the front wall and the rear wall are made of identical, reusable plastic. It is advantageous here that the ribs and / or notches form a transverse connection at least at one point of their total length for the transverse flow of the gaseous medium. Advantageously, the front screens are at least partially provided with an antireflective layer. It is also advantageous if the blowing orifices have an increasing or equal diameter with increasing distance from the supply point of the gaseous medium.

Particular advantages of the target according to the invention are that it is easy to transport and assemble due to its light weight. Due to the special shape, high stacking density is achieved. Used plastic material can be melted again after bombardment and processed for a new target. Chips and residues turn self-absorbing in nature by exposure to ultraviolet radiation. During exercise, the target can be heated to the desired elevated temperature within five seconds. Recognition of the target after 10 rounds with 120 mm bullets or after 200 rounds with 20 mm bullets is ensured and has been proven by experiments. According to the invention, uniform heating of the target surface is provided. Due to the materials used, the training target is insensitive to the effects of weather. When using the target as a daily target, the tube through which the heated gaseous medium is distributed in the target at night is simply removed. Thus, it can not be destroyed by the intervention, thus saving material.

Overview of the drawings

The invention is explained in more detail below by way of example with reference to the drawing. Fig. 1 is a schematic view of the training target from the shooting side. Fig. 2 is a partial cross-sectional view taken along line A-A 'of Fig. 1.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a schematic and simplified view of an exemplary embodiment of a training target Z from the firing side. On a predetermined target frame 10 is mounted a deep-elongated bowl forming a rear wall 1 at a distance which should be at least equal to the caliber of the projectile used. The back wall 1 is made of a plastic material, preferably polyethylene, having a thickness of 1 to 3 mm. A plurality of vertical ribs and / or notches 4 are pushed into the rear wall 1 by deep drawing, which protrude into the interior space 2 formed by the rear wall 1 and the front wall 3 provided on the shelling side. As a result, a high degree of intrinsic stability is achieved, so that the fastening to the target frame 10 can be performed as a clamping. Advantageously, the ribs and / or notches 4 abut against the front wall 3. The ribs and / or notches 4 are provided from a tube 5 which distributes the hot gaseous medium 11 just below the upper edge of the rear wall J, thereby forming transverse connections 9 between the intermediate By means of the transverse connections 9, the most uniform distribution of heat is achieved over the entire target surface. As a result, the visibility of the day or night training target Z remains largely maintained even after a large number of large caliber missile hits. Even damage to the edges of the cup-shaped rear wall 1 does not lead to an increase in the training target Z.

-2GB 286138 B6

The front wall 3 of the training target Z is preferably formed of the same material as the rear wall J.

However, the thickness of the material is always chosen as the film thickness only. This foil is provided by easily releasable fastening means at the outer edge of the rear wall 7. Thus, the training target Z can be removed as a whole after being damaged by a plurality of hits and reprocessed. Due to the low material thickness of the front wall 3, good heat transfer is ensured. The improvement of the thermal representation of the training target Z is given by the coating of the front wall 3 with a non-reflective paint.

The heating is effected by means of an external device, i.e. a source 7, which is connected to the training target 10 Z by means of an inlet 6. In view of the arrangement and arrangement of the device or source 7, the utility model DE-GM 91 12 639 is fully described. The hot gaseous medium is fed to the pipe 5 at the supply point 12. The pipe 5 is made of light metal, for example, and is easily detachably fastened to the rear wall 1 so that it can be replaced quickly in the event of damage. When the training target Z is used as a daily target, the pipe 5 and the heating device 15 are removed, thus preventing their damage by impact or splinters. In the direction of the inner space 2 of the training target Z, the tube 5 has a plurality of discharge openings 8. The diameter D of these discharge openings 8 varies according to the pressure conditions in the tube 5 so that it flows into different sub-regions independently of which consist of ribs and / or notches 4 each having the same amount of hot gaseous medium 11.

Practical tests have shown that practice target Z is very easy to handle and that the representation of the target is very realistic. Training target Z has sufficient mechanical stability under all weather conditions and parts of training target Z can be easily stacked and transported. All parts of the training target Z are reusable, with production and reprocessing costs low.
