Definitions

• the present invention relates to a cartridge according to the preamble of claim 1.
• the effect of the projectile should be based on the impulse delivery in the target (impact effect) and, on the other hand, on a sustained substance (chemical / physical reaction), which prevents the attacker from countering, makes it possible to arrest him or forces him to flee ,
• the aiming accuracy must be so high that with a first shot even at a distance of 20 m an aimed body part on a person rather gets hit.
• the projectile used may not lead to persons any major skin injuries or even bone fractures.
• the projectile should be able to be used successfully against larger animals.
• the impulse body mentioned in the claim undergoes a high coaxial acceleration due to its centrally stored propellant charge and transmits this as a firing energy parallel to the axis to the projectile in contact with it.
• the impact energy density (surface density) in the target is so high that a person who has been hit unprepared by a 40 mm bullet suffers pain and is greatly irritated even at a distance of more than 20 m.
• the agent which emerges on impact of the projectile for example diluted capsaicin, puts the person out of action for a short time, so that resistance can usually no longer be provided.
• the subject invention can be adapted within wide limits to existing weapon systems; in particular, it can be safely fired by means of top-mounted or additional tubes of ordnance guns and grenade pistols.
• Guide means such as guide strips, can be used to generate a twist on the projectile in corresponding weapons, which gives the latter stabilization and, as a consequence, increased target accuracy, claim 2.
• the ratio of the propellant charge from diameter to length mentioned in claim 4 again results in an increase in the end ballistic performance and the accuracy of the target. This is particularly the case in comparison with charges whose diameter is greater than their length.
• the predetermined breaking points mentioned in claim 8 improve the bursting behavior of the front part of the projectile.
• a spherical cap 15 with an outer radius of at least 150 mm prevents eye injuries and / or point loads in the target, which could lead to injuries to the skin or organs, claim 9.
• a further improvement is experienced by the projectile by recesses in the area of the spherical cap according to claim 10 in FIG its bending ability at the target, which also improves its bursting behavior.
• An embodiment of the front part of the projectile in EPDM results in an elastic behavior even when encountering soft targets. This reduces the energy density (energy per unit area) occupied at the target, at the same time increasing the buckling load of the material so that its desired bursting occurs safely; Claim 11.
• FIG. 4 shows the front part, the counterpart to the projectile part FIG. 3
• Fig. 5 is a perspective view from the left, in the inner and on the front part and
• Fig. 6 shows the entire projectile upon impact with the target with its scattering and or spraying.
• a cartridgeed projectile is designated 1. It is inserted into a tube 30 (barrel) of a conventional weapon, shown in simplified form.
• a firing pin which is not marked strikes an ignition element 3 in the bottom of a cartridge casing 2, which has an ignition channel 3 ', which is in operative connection with a propellant charge 6 arranged centrally in a pulse body 4.
• the propellant charge 6 is filled in a cylindrical cavity 5, whose length 1 is greater than the diameter d.
• a combustible mechanical cover 7 (foil) acts as a mechanical and moisture barrier and at the same time as an ignition distributor on the end face of the propellant charge.
• the impulse body 4 has, viewed in the firing direction A, recesses 8 in its end face, which serve for weight optimization or for weight reduction.
• a driver socket 12 which is part of the rear part 9 of a projectile.
• a front part 10 closes the projectile and delimits a hollow space which, in the firing direction A, is filled with an active substance 17.
• a closure pin 14 forms the rear-side barrier in this cavity and serves to balance the weight, ie, by dimensioning and selecting the material, the center of mass of the projectile can be adjusted.
• Integral to the rear part 9 is a thin-walled side guide 11 is present, which rests positively on the inner cylinder shell 2a and after the impulse transmission to the parts 9 and 10 assumes their axis-parallel guidance.
• the enclosed cavity 13 as well as the air space IIa are slightly compressed during the impulse transmission since the driver stub 12 is yielding; which increases the positive connection of the side guide 11.
• the part 10 is designed as a spherical cap 15; the radius R at its cambered surface is 155 mm. Centered and secured radially against rotation, the front part 10 by outer webs 9 ? or inner - webs 9 "which protrude from the rear part 9.
• the projectile is swirl-stabilized by ducts 31 in the pipe 30.
• the trains 31 intersect in a radially ab ⁇ standing guide means, a guide ring 18, a.
• a typical launch speed of 55 m / s there is an initial spin of 45 revolutions per second.
• the plan view Fig. 2 shows again the cartridge case 2, the guide ring 18 and the front-side projectile part 10, with slot-like recesses 16 and stiffeners 20 in the parts 10 and 15th
• FIG. 3 The embodiment of the rear part 9 is shown in FIG. 3 and the front part 10 of FIG. 4:
• FIG. 3 shows a relatively wide sealing lip 9a, which protrudes beyond the inner webs 9 "and frictionally rests on the inner space 10a, FIG. 5, of the front part 10 and radially seals off the interior space for the active substance 17. tet.
• the wedge-shaped configuration of the outer webs 9 ' can be seen, which serve for the slip-free swirl transmission from the rear part 9 to the front part 10.
• the slot-like recesses FIG. 4 and FIG. 5 have a high notch factor and burst immediately upon impact with a target Z, FIG. 6 (predetermined breaking points), thereby releasing the active substance 17 due to the hydraulic pressure forming, so that form S swaths in the immediate vicinity but also in the area.
• a projectile 9 which is intended to be launched in a 40 mm weapon attachment
• its total mass is 72 g, the length 100 mm.
• Its initial velocity vo when leaving the launcher 30 is 58 m / s.
• the maximum flight distance, in the bow shot, is 200 m; the optimal
• Use distance is between 5 to 20 m, ie in the first shot is to hit a target of 20 x 20 cm at this distance safely. At a distance of 50 meters this applies to an area of 55 x 55 cm. In any case (from 5 m flight distance) an energy density of 9 J / cm 2 is not exceeded, so that no skin injuries or fractures occur when the projectile impacts on persons. An unintentional hit on the head of a target person does not lead to any serious facial or eye injuries, since the soft spherical cap has an outer radius over 150 mm.
• the shot energy is not completely transferred to the drive nozzle 12, so that the pulse body 4 also emerges from the launching tube 30 and falls in an inclined trajectory after a short distance on the ground.
• the amount of active ingredient 17 and its density can be compensated by a mass balance on the closure pin 14.
• the resulting center of mass of the projectile 9, 10 can thereby be adjusted to its optimum position in all conceivable cases.
• the projectile sleeve 2 is made of polyethylene (PE); the Heck ⁇ part 9 made of polyacetal (POM).
• the front part 10 is EPDM (ethylene-propylene-diene rubber), which is commercially available under various product names and has a very high elasticity. This results in the desired cross-sectional increase in the target.
• the central arrangement of themaschine ⁇ charge 6, with the geometric relationships shown, causes a concentric energy transfer and thus a precise firing.
• Non-lethal drugs can be highly diluted due to the large volume available and still achieve the desired effect.
• To mark next to colors and per se known fragrances are conceivable that cause a lasting effect in lawbreakers, even in their environment. It is also possible to use chemical marking media which are only later identifiable by physical means, such as UV radiation or halogen detectors, etc.
