Abstract
Official abstract text for this publication.
A method for producing a warhead with directed blasting action involves the step of making an outer casing and arranging therein a charge with a cavity situated at the front end of the charge. An insert whose shape corresponds to the shape of the cavity is arranged on the surface of the charge. The method furthermore involves the step of depositing a material on the insert in an additive manufacturing process. A warhead manufactured according to the method includes an outer casing, a charge with a cavity situated at the front end of the charge, and an insert. A material is deposited on the insert.
First claim
Opening claim text (preview).
1 . A method for producing a warhead with directed blasting action, comprising making an outer casing, arranging a charge in the outer casing with a cavity situated at a front end of the charge, arranging an insert whose shape corresponds to the shape of the cavity on a surface of the charge, depositing a material on the insert in an additive manufacturing process, laying down the deposited material with varying rate or temperature, so that decreases or increases in the deposited material are created. 2 . The method according to claim 1 , wherein the material is deposited in zones on the insert. 3 . The method according to claim 1 , characterized by the step that several different materials are deposited on the insert. 4 . The method according to claim 3 , characterized by the step that the material which is deposited is laid down in two or more overlapping layers. 5 . A warhead manufactured according to the method according to claim 1 , the warhead comprising the outer casing, a the charge with the cavity situated at the front end of the charge, and an insert, wherein the material is deposited on the insert. 6 . The warhead according to claim 5 , wherein the deposited material is arranged in zones on the insert. 7 . The warhead according to claim 5 , wherein a plurality of different materials are deposited on the insert. 8 . The warhead according to claim 5 , wherein the deposited material is reactive. 9 . The warhead according to claim 5 , wherein the deposited material has an amorphous structure. 10 . The warhead according to claim 5 , wherein the the insert contains a plate. 11 . The warhead according to claim 7 , wherein two or more materials are arranged in overlapping layers.
