Definitions

• the invention relates to a floor of the specified in the preamble of claim 1 and u. a. through German Utility Model No. 71 19 938 and U.S. Patent No. 3,952,662.
• the object of the present invention is therefore to develop a simply constructed projectile of the type in question, with which it is possible to act equally effectively against living targets over short, medium and long distances without the risk of being fatally injured.
• the projectile according to the invention is ideally suited for applications where it is important to act against living targets without any risk of death for the same. It is characterized by a particularly large range of action, owing to the large-scale transmission of a meterable kinetic energy from the projectile to the respective target person, which is guaranteed at every target distance.
• This advantage is due to the special interplay of components that are as simple as they are on the market, such as inflatable cushions, pressure sources for filling them and distance sensors.
• the folded cushion with the associated cartridge or the same pressurized gas source is fired, for example, from a hand launcher used for signal rockets, it is the distance sensor that determines the distance to the targeted point of impact and ensures it at a suitable distance from the latter. that the pillow unfolds.
• the projectile in question has a low aerodynamic resistance with its maximum range that can be controlled by the launcher. With the process of inflating the cushion, the latter then increases to such an extent that in a very short time (of the order of 0.01 to 0.1 s) the floor speed drops to zero. There is therefore the interesting possibility of influencing the kinetic energy of the projectile via the time difference between the cushion unfolding and the impact of the unfolded cushion on the target.
• the speed at which the cushion is inflated is a further adjustable parameter in the embodiment of the invention. It can be used to control the volume of the pillow, its aerodynamic resistance and thus the time characteristics of the bullet speed. If the cushion is inflated very close to the person to be met, an additional impulse can be transmitted to this person through the build-up of internal pressure in the cushion. Regarding the possibility of varying the inflation pressure according to a further design feature, the following should be noted: If said pressure is high, that is to say the pillow is very well filled, the result is a comparatively hard blow in the target, which in addition acts on a relatively smaller target area. At lower pressure levels, however, such a blow is softer. It is also distributed over a larger impact area and can also transmit a considerable amount of pressure with the appropriate kinetic energy.
• FIG. 1 in the form of a schematic diagram, an embodiment of the projectile according to the invention in the application and
• FIG. 2 a diagram which provides information about how a projectile execution according to FIG. 1 behaves with respect to the drop in speed on the way to the target and the effective range compared to projectiles of known design.
• FIG. 1 shows a hand launcher 1, specifically immediately after a projectile 2 has been accelerated in the direction of the arrow 3 towards a person 4 standing away.
• the floor 2 has a folded, inflatable cushion 5 in the front area.
• a cartridge 6 generating compressed gas.
• It also has its own distance sensor 7. With the same is at a defined floor distance 8 from the Person 4 triggered the inflation process.
• the consequence of this, as can be seen in FIG. 9, is that the cushion 5 is rapidly deployed by inflowing compressed gas 10.
• Distance sensors of a similar type are often used in conventional projectiles.
• Figure 2 shows in a right-angled coordinate system with the distance from the launch site 1 1 as the abscissa 12 and the initial projectile speed as the ordinate axis 13 velocity profiles of a projectile with consistently high aerodynamic resistance 14, a projectile with consistently low aerodynamic resistance 15 and a projectile according to the invention 16 with controllable time of deployment 17. Furthermore, are marked
• the definition of the different areas of action 18, 21 and 24 depends on the mass, speed and geometry of the respective floor.
• the drop in speed is proportional to its aerodynamic drag.
• the projectile according to the invention can be controlled by the inflation size, while the effectiveness of the target can be influenced by the degree of impact. With the possibility of a composition of two trajectories of different speeds falling shown and the arbitrary choice of the transition time from one to the other trajectory path, the prerequisites for the projectile according to the invention are created for a considerable enlargement of the effective range and the effective intensity.
