Abstract: A method for engaging one or several aerial targets by means of a firing group (10) of autonomous, but cooperating, firing units (12, 112), wherein each firing group has a fire control unit (14, 114) and at least one weapon (16, 116). Several firing units (12, 112) are linked by a signal transmission system (70), which connects their fire control units (14, 114). Each fire control unit (14, 114) autonomously monitors its airspace area for enemy aerial targets. Subsequently, each fire control unit (14, 114) determines a threat assessment, for which the monitoring results of all fire control units (14, 114) are used. The selection of an aerial target to be engaged by a firing unit (12, 122) is subsequently made by the associated fire control unit (14, 114) on the basis of,the threat assessment and on the basis of the status of the weapons (16, 116) of the entire firing group (10).

Abstract: A soldier (A) carries a weapon, on which a laser device (1) is mounted, which is used for illuminating a harness device (6) on the body of another soldier (B). The laser device and the target device each include a microprocessor as well as an ultrasound unit and/or a radio unit (72, 71) such that, if the laser device does not receive a response from the target device within a period of time Ta following the transmission of a bundled, coded laser beam, it transmits another laser beam with different coding, which causes the ultrasound unit and/or the radio unit of the target device to transmit an acknowledgement which can be received by the ultrasound unit and/or the radio unit of the laser device.

Abstract: A soldier carries a weapon on which a laser device (1) is mounted, which is used for illuminating a harness device (6) on the body of another soldier. This harness device is provided with sensors (61, 62, 63, . . . ), which perform detection tasks for several applications in connection with arbitrary simulation scenarios in the course of exercises and battles. The laser device (1) has a laser target illumination element which is designed for transmitting tightly bundled laser beams (11), as well as chopper means for transmitting laser beams which are not only coded, but also chopped at a predeterminable frequency. The sensors contain tuning means for obtaining an alternating electrical signal from the received chopped laser beams, which is supplied to a pre-amplifier connected upstream of a discriminator. A very sensitive laser identification system results due to the fact that the electrical signal obtained in this manner can be very strongly amplified.

Abstract: The determination of the active projectile velocity required for the correction computation and the correction of the disaggregation time (Tz(vo) are performed in a projectile after it has been fired. The velocity measurement takes place in the form of a measurement of a first time (t) which is required for a defined number of revolutions (Nm) of the projectile, wherein a velocity difference, which must be multiplied by a correction factor, is expressed by the actual projectile velocity and a lead velocity of the projectile by means of a time difference (t−tm) formed from the first time (t) and a predetermined second time (tm).

Abstract: The transmission of the disaggregation time takes place in the area of the conveying path of the projectiles (18) between a a magazine of the gun and the start of the flight path of the projectile (18), wherein the disaggregation time (Tz(Vo_typ)) is corrected by means of a delay time, which is a function of the selected transmitting point.

Abstract: A method and device for cooling a gun barrel wherein coolant is provided to the gun barrel via a nozzle arranged at the downstream end of a pressure feed line arrangement. The coolant is originally conveyed from a reservoir into a pressure cylinder, while the pressure feed line between the pressure cylinder and the nozzle is closed. Thereafter, the coolant in the pressure cylinder is placed under a predefined operating pressure. Prior to firing a round, the pressure feed line is opened, so that the coolant flows to the gun barrel before firing. When firing a shot, the coolant in the gun barrel is compressed to a pressure above the predetermined operating pressure by the firing gases and pushed out of the gun barrel. In the process, the coolant is expanded into a buffer reservoir adjacent to the nozzle and is injected back into the gun barrel after the gas pressure built up has been reduced to the predetermined operating pressure.

Abstract: The simulation system is used in the course of firing exercises, in particular with a laser beam, for simulating conditions which would arise if actual ammunition were used. For identifying a responder device (2), an interrogation device (1) transmits a coded radiation, which is detected in the responder device and is converted into electrical signals, which are supplied to a central unit (25) on the receiving end for transmitting identification messages back to the transmitting device in accordance with decisions made by this central unit (25). The interrogation device generates laser radiation or electromagnetic pulses or pulse bursts containing information which is coded in such a way that the response pulses being sent back by the responder device to the interrogation device additionally enable a central unit (15) on the transmitting end to calculate the distance between the interrogation device and the responder device.

Abstract: Cartridges (5) are guided during a loading phase shortly before reaching the automatic cannon (1) onto a first track, which differs from the conveying direction of the conveyor chain (14) and are guided at a greater distance from the revolving drum (13) around the shaft (15) of the revolving drum, and conveyed on. In a firing phase, the cartridges (5) are guided shortly before reaching the automatic cannon (1) onto a second track, which differs from the conveying direction of the conveyor chain (14), are guided around the shaft (15) of the revolving drum (13), and are sequentially brought into a firing position directly behind the revolving drum. After having been fired and ejected, the empty cartridge cases (6) are caught and are transported on the first track into a magazine (4).

Abstract: In connection with this ammunition-feeding device, an axial transport device (19) with a conveyor chain (34) is provided between a conveyor (6) and a transfer station (20) for transferring cartridges (2) to a revolver drum (25) of a revolver cannon, by means of which the cartridges (2) are displaced in their longitudinal direction during transport vertically in respect to the movement direction of the conveyor chain (34). A buffer shaft (35) is provided for driving the conveyor chain (34), wherein the drive by means of the buffer shaft (35) takes place in such a way that, prior to being transferred to the transfer station (20), the cartridges (2) are brought into a buffer position.

Abstract: Anchoring of a spin-stabilized projectile with a sabot body is provided by grooves arranged on the fin-stabilized projectile, which are engaged by ring-shaped protrusions provided in an axial bore of the sabot body. The distance of the first protrusion from the predetermined breaking points of the sabot body and the height of the protrusions are selected in such a way that the deformation at the predetermined breaking points in case of assembly-related spreading of the segment lies in the resilient range.

Abstract: The service life of gun barrels of firearms with a high cyclic rate can be extended by means of the cooling device of the invention. To this end, coolant (7) is conveyed from a reservoir (6) into a pressure cylinder (10) by drawing up a hydraulic cylinder (13), while the feed line (14) to the gun barrel is closed. Thereafter the hydraulic piston (13) is moved in the opposite direction by a pressure reversal and the coolant (7) in the pressure cylinder (10) is placed under a defined operating pressure. Prior to triggering a volley, the feed line (14) is opened, so that the coolant (7) can flow via the feed line (14) and the nozzle (16) to the gun barrel (1). The coolant (7) is pushed back by the gas pressure respectively being created when a shot is fired, and following the lowering of the gas pressure to the operating pressure, it is again injected into the gun barrel (1).

Abstract: In connection with a projectile, the effective substance (4) is designed as a projectile core (3), which is held in place by a propulsion reflector sheath (1) and a propulsion reflector back (2).
