Definitions
- the invention relates to a practice projectile for barrel weapons, especially a smashed bullet, according to the generic term of claim 1.
- a practice projectile for barrel weapons especially a smashed bullet
- the expert understands a practice floor, which breaks down when it hits a target medium so that the danger area compared to a standard training floor is reduced and thus minimized.
- the Reduction of the rebound risk in the target is at system compatibility and a indoor and outdoor ballistics according to the standard practice floor required.
- the dismantling of a floor is caused by the floor impact energy from projectile mass and impact speed, through the target hardness and through the bullet strength influenced.
- the target hardness are as parameters the target medium, such as sand, and the impact angle and construction for bullet strength and the selected material for the crushed bullet to call.
- a typical practice floor is from DE 23 09 589 C3 known, which is about a normal in shape and weight combat missile corresponds.
- This practice floor exists essentially one with a metal powder mass filled shell, with predetermined breaking points is provided.
- the metallic shell is like this dimensioned that the compressed and with a polymerizable Product mixed filling powder mass at one Serve on the practice floor on the radially arranged tapered breaking area trained predetermined breaking point exit. This causes the projectile to disintegrate on Aim and visually mark the meeting point.
- DE 23 09 589 C3 also happen when the practice floor hits at an angle, so the possibility of ricocheting is turned off is.
- Shattered bullets were in a systematic series examined whose mechanism of action on with metal powder filled and provided with predetermined breaking points Storey caps are based. It was demonstrated that the Ability to disassemble such training projectiles on impact on a flat inclined sand bed below one certain residual impact energy can no longer be increased is, without thereby their security against firing, namely ballistic security suffers. To such Practice shots the disassembly distance to the desired one To increase dimension, the wall thicknesses in the area would have to the predetermined breaking point should be made so thin that the practice projectiles are either at the feeder into the weapon or through the shot in the gun barrel be destroyed.
- a training projectile for barrel weapons to create the type mentioned at the beginning very low residual energies in the target and on impact on a flat inclined, soft target medium in at least two parts is disassembled, and an increase the disassembly distance is achieved.
- the increase in Disassembly distance achieved in that at least two spherical bodies pressed into the projectile hood be in their contact level in the floor hood radial predetermined breaking points are provided.
- the remaining wall thickness in the floor hood in the area of the predetermined breaking points can be dimensioned so that on the one hand ensures handling and ballistic safety and, on the other hand, the ability to disassemble nevertheless increased beyond the known level can be.
- the practice floor 1 corresponds in terms of floor configuration and mass essentially a standard practice floor and one Standard combat bullet.
- a molded body 8 Face on the tailgate 2 lies in a circular recess 7 a molded body 8, which has a central through opening or blind bore open to the top 5 of the floor 9 has.
- Receiving the ball has the molded body 8 in the front Area of the recess 9 a spherically formed Storage area 31.
- Ball 11 of preferably smaller diameter than the ball 10.
- the ball 11 is in the floor cap 6 pressed in and lies with the ball 10 facing Surface on the ball 10.
- the two spherical bodies 10 and 11 With the help of the molded body 8 are the two spherical bodies 10 and 11 in the direction of the tip 5 of the floor in the hood 6 firmly inserted or braced.
- a radially oriented predetermined breaking point 13 In the perpendicular to the longitudinal axis 12 of the floor The contact level of the two bodies 10 and 11 is in the Storey hood 6 is a radially oriented predetermined breaking point 13 provided. Below the predetermined breaking point 13 in the direction of the tailgate 2 there is another radial predetermined breaking point 14, which is an annular groove or recess 15 in the molded body 8 is opposite. At 16 are in addition to the radial predetermined breaking points 13, 14 still indicated longitudinal breaking points.
- FIG 4 is the impact of the practice floor 1 in a target medium 17.
- the target medium 17 is made of sand and is at a flat angle 18 from about 15 ° incline.
- the approaching Practice floor 1 hits the surface of the Target medium 17 on.
- the floor cap 6 arise on the floor Forces indicated by arrows 19 and 20. Due to these forces 19 and 20 there is a roll the spherical body at their points of contact around the center of the adjacent sphere 10 or 11. Effect the resulting force components an exact tearing open of the projectile hood 6 in the radial Predetermined breaking point 13.
- Arrows 21, 22 and 23 the breakdown of the impact energy into individual Power components.
- the arrows 24 indicate the swirl movement of the practice floor 1, while arrow 25 the Flight direction of the projectile represents and arrow 26 the when the practice floor 1 hits the target medium 17 the direction of force opposite to the direction of flight 25.
- the practice floor 1 in Figure 2 differs from the training floor according to Figure 1 only by the other Design of the body used 27 and 28.
- This Cylindrical bodies 27 and 28 have the mutually facing contact surfaces formed spherically, protruding knobs 29 and 30.
- the touching Nubs 29 and 30 of the bodies 27 and 28 are in the circular section of Figure 2 clearly highlighted.
- In the plane of contact of the two bodies 27 and 28 is again the radial predetermined breaking point 13.
- Figure 3 is a mixture of that in Figure 1 and in Figure 2 shown body shown.
- the floor hood 6 is in the direction of the projectile tail on the molded body 8 the spherical body 10 inserted, the surface on the spherical knob 30 of the cylindrical Body 28 abuts.
- the body 10 and 28 the radial predetermined breaking point 13.
