Abstract

A method for combating target objects (27, 28) by means of bomblets (15) and a bomblet carrier body (1) for carrying out such a method are to be improved in such a way that the combat effect of the bomblets (15 ) is increased. For this purpose, above the standard height (24) for covering a target area (12) with bomblets (15), it is determined whether there is a target object (27) to be specifically fought in an inner, reduced target area (13). In this case, the bomblet output is delayed until the carrier body (1) has fallen to the reduced height (29) for occupying that reduced target area (13) with its bomblets (15). For target detection in the inner target area (13), a sensor (4) is arranged in the carrier body tip (3), arranged behind an interior lens (22) optimized for the sensor function in terms of material and geometry. This is uncovered by blasting off an external lens (19) which is more favorable in terms of flight dynamics, before reaching the detection height (26) above the standard height (24) for occupying the non-reduced standard target area (12).

Description

The invention relates to a method according to the preamble of claim 1 and a carrier body according to the preamble of claim 2.

The generic method and the generic device are known from DE-AS 17 03 781. The ignition of the ejection propellant charge must take place at such a height that the bomblets - essentially parallel to the direction of incidence into the target area - are ejected backwards from the carrier body and whose steep flight into the target area undergoes a mutual fan-shaped widening, a sufficiently large scattering and thus Occupy target area; while, on the other hand, if the target area is too large, the probability of being hit by individual target objects operating in the target area is only low due to the limited number of bomblets in a carrier body.

The invention has for its object to improve the effect of fighting individual targets in the target area of bomblets.

This object is achieved according to the invention essentially in that the method of the generic type is additionally configured according to the partial features of the characterizing part of claim 1, while the carrier body of the generic type also has the partial features of the characterizing part of claim 2.

The core idea of the solution is therefore to be seen in not only the altitude-dependent control for the Z _ü n the ejection propellant charge with a sensor to provide the support body; but also to provide this or an additional sensor for - before dropping the support body to the standard Height for the discharge of the bomblets - to examine an inner area of the target area for whether there is a specific (specified) target object to be combated. If this is the case, the bomblet output is not yet at the standard height, but is delayed; and thus only when a reduced height is reached, from which the bomblet stray field is essentially concentrated on the smaller sensor detection field inside the larger standard target area. In this case, the effect of the bomblet use is increased because its individual effects are concentrated in the reduced target area and thus in the immediate vicinity of a target object to be specifically combated; with the result that the bomblet carrier body is used more likely. If, on the other hand, the sensor does not identify a specific target object in that inner target area when it enters the target area, the bomblets are ejected without delay; So when the standard height is reached with the correspondingly larger scattering area around the inner target area, in which the normal probability of bomblet hits is given in target objects which are located outside the sensor detection area.

Similarly, the warhead of a cruise missile or a ballistic missile can be used as a carrier body, if by its ballistic or controlled flight a sufficiently steep dip of the carrier body into the target area is given. Because then the bomblets can simply be concentrated on the area-reduced, inner target area by (with timely detection of a specific target object to be found therein) the bomblet output is delayed until it reaches a lower height above the target ground. In addition, the design effort for the installation and operation of the sensor is then relatively low because it can be installed rigidly and oriented along the longitudinal axis of the carrier body in the tip thereof.

The sensor itself can also be simple, that is to say inexpensive, since it does not have to have high resolution or strong bundling. Rather, it is sufficient for the desired improvement of the bomblet use that it covers a detection area from just above the standard discharge height at the bottom, which is smaller than the standard spreading area of the bomblets.

Additional developments as well as further features and advantages of the invention result from the following description of a basic example for a device according to the invention for practicing the method according to the invention, which is shown in a highly simplified manner while restricting it to the essentials.
It shows:

• Fig. 1 shows a projectile as a bomblet carrier body, partially cut, and
• Fig. 2 shows the carrier body after blasting off its external lens in a steep approach to the target bottom.

A bomblet carrier body 1 is outlined in FIG. 1 as a projectile 2 that can be fired by a barrel weapon. It consists of a projectile tip 3 with sensor 4 and electronic signal processing device 5, an intermediate part 6 with ejection propellant 7, a projectile jacket 8 with ejection plate 9 and a projectile floor 10 with guide band 11.

The bomblets 15 to be transported from the projectile 2 via the target area 12/13 (FIG. 2) and to be ejected there in the direction of the projectile longitudinal axis 14, opposite to the projectile flight direction, are arranged in the projectile casing 8 between the ejection plate 9 and the floor 10 , namely lined up in a rod shape and packed concentrically around the longitudinal axis 14 of the projectile. For the ejection of the bomblets 15, an ignition device 16 in the intermediate part 6 is triggered by the signal processing device 5, which ignites the ejection propellant 7. The pressure exerted on the ejection plate 9 in the direction of the projectile rear 17 is transmitted to the floor 10 via the rod-shaped packing of the bomblets 15; whose screw connection 18 shears off with the projectile jacket, so that the bomblets 15 are pushed out of the projectile 2 against the direction of flight by the now opened projectile rear.

The contour of the projectile tip 8 is given by an aerodynamically shaped outer lens 19 made of highly durable material, in particular based on light metal. It is screwed to the side with an ogive base 20 on the back of the projectile tip 3. The detachable charges 21 arranged there can be used to detach the outer goggles 19 from the base 20, controlled from the signal processing device 5. This exposes an interior ogive 22, which is designed as a hollow hemisphere and whose geometry and Material is designed in accordance with the electromagnetic radiation with which the sensor 4 works in order to keep distortions and losses when the radiation passes through the interior lens 22 as low as possible.

The sensor 4, which is preferably designed as a millimeter-wave parabolic mirror 23 with a central axis lying in the longitudinal axis 14 of the floor, is arranged in the floor tip 3 behind the interior lens 22. The device for converting received electromagnetic signals into information is expediently structurally combined with this, and is evaluated by the signal processing device 5 arranged behind it for blasting off the ogives 19 and then for ejecting the bomblets 15.

The carrier body 1 is designed - if necessary in accordance with the final phases - to approach the target area in a relatively steep dive. For the construction and installation of the sensor 4, as mentioned, no particular effort is required; it suffices for a pick-up device which is permanently installed in the projectile tip 3 coaxially to it and oriented in advance, as is provided, for example, by the parabolic mirror 23 for millimeter waves,

The target area 12 at the base 25 represents an oval-distorted circular area depending on the angle of fall and the flight movements of the support body 1. This area corresponds to the stray field over which the bomblets 15 spread over a standard height 24 of, e.g. Spread 300 m above ground 25.

Already above this standard height 24, after the external lens 19 has been blown off, the target detection, e.g. at a detection height 26 of 400 m above ground 25. The object of this target detection is the recording of reflection or intrinsic radiation from target objects 27 in the sensor detection area, which corresponds to an inner, reduced target area on ground 25; to which the stray field of the bomblets 15 could be reduced by delaying the bomblet output until a reduced height 29 above ground 25 is reached. Because of the reduced stray field, the bomblet output at this reduced height 29 results in a concentration of the bomblets 15 on the inner target area 13 and thus on the target object 27 located therein, which is attacked with the high density of almost all bomblets 15 and is most likely out of action is set. Thus, the effectiveness of the use of bomblets 15 against target objects 27 can be significantly increased by a simple variant of the sensor technology developed for combat observation and target detection here to delay the bomblet output until reaching a lower height 29, if in the inner target area 13 defined target object 27 was detected, is used.

If, on the other hand, no specific target object 27 to be combated - the radiation or geometry parameters of which are specified in the signal processing device 5 for target selection - can be identified in the interior 13 of the target area 12, which can be detected by bomblets 15, then as usual, the bomblet output already takes place when the standard height 24 is reached, for the distribution of the bomblets 15 over this standard stray field as the normal target area 12. Target objects 28 present therein cannot be combated with the high density of all the bomblets 15; but there is a normal likelihood of hitting 15 hits with at least some of the scattered bomblets and causing at least damage to target 28 to reduce combat value.
