Abstract

The invention relates to a method and an apparatus for engaging targets at different range with the aid of ballistic projectiles which are fired from a compressed-gas weapon (1), the gas pressure of which can be regulated. In order to engage targets at different ranges in a simple manner, without changing the elevation angle of the weapon, the invention proposes that the compressed-gas weapon (1) be connected to a fire control installation (7). In this case, the fire control installation (7) determines the muzzle velocity which is required in order to hit the target from the range to the target or target region, as predetermined by the user of the compressed-gas weapon (1) or as determined automatically by means of a laser rangefinder, and the elevation angle of the weapon barrel (3), as determined automatically for example with the aid of an angle sensor (5), as well as the mass of the projectile of the corresponding round. The fire control installation (7) then uses this velocity value, together with a table which is stored in a memory (10) in the fire control installation (7), to determine the gas pressure required for firing the projectile, and produces an actuating signal which appropriately adjusts the gas pressure in the compressed-gas weapon (1).

Description

 DESCRIPTION

Method and device for fighting targets of different

 Range

The invention relates to a method for controlling targets of different range by means of ballistic projectiles which are fired from a gas pressure gun with adjustable gas pressure. The invention further relates to an apparatus for carrying out the method.

Ballistic projectiles are usually fired with the help of a pyrotechnic drive (propellant charge) from a gun barrel. To vary the range of such projectiles, either the elevation angle of the gun barrel or the propellant charge must be changed. Both are extremely time consuming. In addition, can not achieve a sufficiently accurate stepless range control with these known methods.

A pneumatic projector for fireworks projectiles is described in WO 93/25861 A1 and has a drum, wherein the respective drum tube is rotated over the pressure vessel, so that the projectile located in this tube can be ejected.

The non-prepublished DE 10 2009 041 094.5 deals with a gas pressure weapon, in which a range or energy control is integrated without drive bullets. The initiation of these unpowered projectiles takes place via known induction methods. The range control or projectile energy control makes it possible to determine the firing and thus impact velocity of the ammunition or active body on the distance to be deployed in such a way that the ammunition can be fired at different individual distances, in particular the non-lethal ammunition still not acting lethal. This has the consequence that the muzzle energy is gradually can be adjusted to the particular application or the respective required operating range. This projectile energy control can be realized by controlling the shot pressure. The control of the shot pressure can be done once by controlling the operating gas pressure and / or by influencing the valve characteristic (valve opening time). In addition, since an incorrect choice of pressure could have catastrophic consequences, not only a purely electronic pressure level check is proposed.

The invention has for its object to provide a method with which it is possible to combat different distant targets without changing the elevation angle of the weapon. Furthermore, an apparatus for carrying out this method should be specified.

This object is achieved with respect to the method by the features of claim 1 and with respect to the device by the features of claim 4. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

The invention is based essentially on the idea of connecting the adjustable gas pressure weapon with a fire control system. In this case, the fire control system determines from the predetermined by the shooter or automatically determined by a laser rangefinder distance of the target or target area and, for example, using an angle sensor automatically detected elevation angle of the gun barrel and the mass of the projectile of the corresponding ammunition, the muzzle velocity of the projectile, which is required to hit the target. From this speed value, the fire control system then determines, for example with the aid of a previously stored in a memory table the necessary to launch the projectile gas pressure and generates a control signal which adjusts the gas pressure in the gas pressure chamber of the gas pressure weapon accordingly.

By the method according to the invention a fast targeting is possible without the weapon must be directed or readjusted. The range of the projectiles is practically infinitely variable by increasing or decreasing the gas pressure. The effect of different projectile masses, resulting for example from a printed on the respective floor identifier and automatically by The device can be determined, are taken into account in a simple manner that the pressure in the gas pressure chamber (and thus the projectile velocity corresponding to this pressure) is changed accordingly.

The error rate is low, since not the user of the gas pressure gun must direct each time again, since the device of the invention automatically determines the required to launch the projectile pressure and controls.

In addition, on floors where a disassembly of the projectiles is to take place over a target area, done in a simple manner by the fact that the Feuerleitanlage from the predetermined height of the decomposition process, the elevation angle of the gun barrel and the mass of the projectile the required delay time between launch and initiation of the determined decomposition process determined and generates a delay time corresponding control signal, which is transmitted to a delay element of the projectile.

Finally, for example, in direct combat of a target without changing the elevation angle, the projectile energy when hitting the target by the appropriate choice of gas pressure and thus the muzzle velocity of the projectile can be adapted to the target (this can, for example, in the case of non-lethal projectiles, which on demonstrators or the like will be of importance).

Further details and advantages of the invention will become apparent from the following, with reference to figures explained embodiments. Show it:

1 shows a block diagram of the weapon system according to the invention and

2 shows a diagram from which the effect of the weapon system can be seen.

In Fig.1 1 is indicated a gas pressure weapon. The gas pressure gun 1 has the rear side a pressure chamber 2 and the front side at least one gun barrel 3, from which a bullet, not shown, can be fired without its own drive.

The pressure chamber 2 is connected to a control input 4, via the control signals for Specification of the pressure with which the respective projectile is to be fired from the barrel 3, are entered. In addition, an angle sensor 5 for automatically determining the elevation angle of the gun barrel 3 is provided. Furthermore, the gas pressure gun contains an electronic reading device 6 for automatically scanning the projectiles already located in the gun barrel and provided with identifiers.

The control input 4 and the outputs of the angle sensor 5 and the reading device 6 are connected to a fire control system 7. This includes a Feuerleitrechner 8 and is also connected to an external input device (for example, a keyboard) 9.

If, for example, the user of the gas pressure weapon 1 (for example a police officer) shoots at a certain target (for example a demonstrator) with a non-lethal projectile (for example a demonstrator), which is about 50 m away from him, he merely gives the information Input device 9 this distance value and loads the gas pressure gun 1 with a projectile.

The fire control system 7 then asks automatically from the angle sensor 5 the existing elevation angle and the reading device 6 the ammunition type, and thus the mass of the projectile, from. From these values, in conjunction with the entered distance of the target, the fire control computer 8 automatically determines the muzzle velocity (or energy) of the projectile required to hit the target. With the help of a stored in a memory 10 of the fire control system 7 table is then determined by the Feuerleitrechner 8 from the speed or energy value required for launching the projectile gas pressure and generates a corresponding control signal.

This control signal reaches the control input 4 and causes the gas pressure in the pressure chamber 2 is increased or decreased, so that the gas pressure required to hit the target.

When the gas pressure is reached, the latter acts on the projectile at the rear, so that the projectile is ejected from the weapon barrel 3 at the appropriate speed.

From Figure 2, the range control of the projectiles described above is again shown schematically. The altitude H is dependent on the flight distance D a projectile shot, which is fired at two different elevation angles. As can be seen in FIG. 2, a range change can be achieved by increasing or decreasing the gas pressure p (which corresponds to an increase or decrease in the muzzle velocity or projectile energy) for a given angle of elevation.

If the projectile (such as a lightning projectile) is provided with a bursting charge which is to disassemble it over a target area at a predetermined height, then the corresponding user of the gas pressure weapon 1 only needs to input the height above the target area into the fire control system 7 via the input device 9. The fire control computer 8 then calculates the delay time between the launch and the initiation of the intended dismantling process of the projectile, taking into account the distance of the target area, the elevation angle of the weapon barrel 3 and the mass of the projectile, and generates a control signal corresponding to the delay time , This control signal is then transmitted to a delay element of the projectile before or at its launch.

To transmit the data relating to the delay time on the projectile, the weapon barrel 3 of the gas pressure weapon 1 are provided on the outlet side with an inductive transmitter 1 1 (FIG. 1) and the projectile is provided with an inductive receiver.

With the device according to the invention, it is also possible in a simple manner to change the projectile energy occurring in the target in a directly directed to a target gas pressure weapon. For this purpose, with the help of the fire control system 7 from the predetermined projectile energy in the target required for launching the target gas pressure of the gas pressure gun 1 is determined and generates a corresponding control signal which changes the gas pressure of the gas pressure gun 1 in the desired manner.
