Abstract
Abstract Minimum probability of collision during the dispensing procedure is desirable in the distribution of submunition, such as mines, bomblets, or subsidiary projectiles by means of rockets or shells. For this purpose, a dual ejection process is provided wherein the individual submunitions are accommodated severally in special dispensing units which units, in turn, are inserted as secondary elements in the rockets or shells. Upon primary ejection over the target area, the dispensing units are ejected, stabilized at a distance from the rockets or shells, and subjected to a deceleration different from that of the rockets or shells so that the flight paths diverge, thus precluding collision. Subsequently, in a secondary ejection, the submunition is ejected from the dispensing units.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
140 words
A process for the distribution of submunition wherein a plurality of individual submunitions completely accommodated within at least one dispensing unit of a carrier projectile are released at a predetermined point in time, characterized in that the at least one dispensing unit is ejected in a defined fashion at a predetermined instant from the carrier projectile by being guided during the ejection movement in the carrier projectile, and is maintained in a stable flight position at a spacing from the carrier projectile; and that the carrier projectile and the at least one dispensing unit are differently decelerated so that the trajectories of the carrier projectile and the at least one dispensing unit diverge, and finally the plurality of individual submunitions which are completely accommodated within the at least one dispensing unit are ejected from the at least one dispensing unit.
Claim 2
Dependent Claim
140 words
A process for the distribution of submunition wherein a plurality of individual submunitions completely accommodated within at least one dispensing unit of a carrier projectile are released at a predetermined point in time, characterized in that the at least one dispensing unit is ejected in a defined fashion at a predetermined instant from the carrier projectile by being guided during the ejection movement in the carrier projectile, and is maintained in a stable flight position at a spacing from the carrier projectile; and that the carrier projectile and the at least one dispensing unit are differently decelerated so that the trajectories of the carrier projectile and the at least one dispensing unit diverge, and finally the plurality of individual submunitions which are completely accommodated within the at least one dispensing unit are ejected from the at least one dispensing unit.
Claim 3
Dependent Claim
29 words
A process according to claim 1, wherein each submunition is ejected from the at least one dispensing unit against the flight direction of the at least one dispensing unit.
Claim 4
Dependent Claim
35 words
A process according to claim 1 or claim 2, wherein each submunition is ejected only when the at least one dispensing unit has been braked to a velocity which can be withstood by the submunition.
Claim 5
Dependent Claim
36 words
A process according to claim 3, wherein the at least one dispensing unit prior to ejection of the submunition is decelerated to preferably subsonic speed with the aid of a braking device for the supersonic range.
Claim 6
Dependent Claim
177 words
A process for the distribution of submunition wherein a plurality of individual submunitions accommodated in at least one dispensing unit of a carrier projectile are released at a predetermined point in time, characterized in that the at least one dispensing unit is ejected in a defined fashion at a predetermined instant from the carrier projectile by being guided during the ejection movement in the carrier projectile, and is maintained in a stable flight position at a spacing from the carrier projectile; and that the carrier projectile and the at least one dispensing unit are differently decelerated so that the trajectories of the carrier projectile and the at least one dispensing unit diverge, and finally the plurality of individual submunitions are ejected from the at least one dispensing unit, wherein the at least one dispensing unit is ejected from the carrier projectile so as to maintain a predetermined spacing therefrom in accordance with the relationship of (0.02 to 0.2)s×V c , where V c is the velocity of the carrier projectile at the moment of ejection in m/s.
Claim 7
Dependent Claim
177 words
A process for the distribution of submunition wherein a plurality of individual submunitions accommodated in at least one dispensing unit of a carrier projectile are released at a predetermined point in time, characterized in that the at least one dispensing unit is ejected in a defined fashion at a predetermined instant from the carrier projectile by being guided during the ejection movement in the carrier projectile, and is maintained in a stable flight position at a spacing from the carrier projectile; and that the carrier projectile and the at least one dispensing unit are differently decelerated so that the trajectories of the carrier projectile and the at least one dispensing unit diverge, and finally the plurality of individual submunitions are ejected from the at least one dispensing unit, wherein the at least one dispensing unit is ejected from the carrier projectile so as to maintain a predetermined spacing therefrom in accordance with the relationship of (0.02 to 0.2)s×V c , where V c is the velocity of the carrier projectile at the moment of ejection in m/s.
Claim 8
Dependent Claim
54 words
A process according to claim 5, wherein an ejection charge is provided in the carrier projectile for ejecting the at least one dispensing unit from the carrier projectile, the ejection charge being dimensioned so as to enable the maintenance of the predetermined separation between the carrier projectile and the at least one dispensing unit.
Claim 9
Dependent Claim
107 words
A process according to claim 1 or claim 5, wherein the ejection of the at least one dispensing unit from the carrier projectile and the ejection of the plurality of individual submunitions from the at least one dispensing unit are arranged so that the trajectories of the carrier projectile, the at least one dispensing unit and the individual submunitions diverge from one another, whereby collisions between the individual submunitions and the at least one dispensing unit and the carrier projectile are avoided and reproducible ballistic relationships for the individual submunitions are achieved so as to provide an even distribution of the individual submunitions in a target area.
Claim 10
Dependent Claim
113 words
A process according to claim 7, wherein the carrier projectile carries a plurality of dispensing units, each of the dispensing unit accommodating a plurality of individual submunitions, each of the dispensing units being ejected in a defined fashion at a predetermined instant from the carrier projectile by being guided during the ejection movement in this carrier projectile, and being maintained in a stable flight position at a spacing from the carrier projectile, the carrier projectile and the plurality of dispensing units being differently decelerated so that the trajectories of the carrier projectile and the plurality of dispensing units diverge, and finally the plurality of individual submunitions are ejected from the respective dispensing units.
Claim 11
Dependent Claim
56 words
A process according to claim 3, wherein the at least one dispensing unit at the time of ejection from the carrier projectile is moving at supersonic speed, and the at least one dispensing unit prior to ejection of the submunition is decelerated to subsonic speed with the aid of a braking device for the supersonic range.
