Abstract
A warhead system, method and apparatus. A warhead includes a liner having a logitundinal axis that runs down the center of the liner. The liner includes a liner pattern and a liner shape. The liner shape is selected and a radial distance from the longitudinal axis is selected. The liner pattern is warped as a function of the selected distance and the shape of the liner to reduce the effects of spoking in the post-detonation fragmentation pattern at the selected distance. The liner is then formed as a function of the warped liner pattern.
Claims26
A warhead, comprising:
- an approximately cylindrical liner having an outside surface and a longitudinal axis that runs down the center of the cylinder;
- a forward bulkhead attached to the liner;
- an aft bulkhead attached to the liner;
- and
- an explosive deposited inside the liner;
- wherein the liner includes a liner pattern, wherein the liner pattern is selected to cause the liner to form a post-detonation fragmentation pattern having a plurality of radially expanding projectiles when the explosive is detonated;
- and
- wherein the pattern includes a repeating pattern which reduces spoking in the post-detonation fragmentation pattern .

16-24. (canceled)
A method of manufacturing a warhead, comprising:
- forming an approximately cylindrical liner having an outside surface and a longitudinal axis that runs down the center of the cylinder;
- attaching a forward bulkhead to the liner;
- attaching an aft bulkhead to the liner;
- and
- depositing an explosive inside the liner;
- wherein forming the liner includes selecting and applying a liner pattern that forms, when the explosive is detonated, a post-detonation fragmentation pattern having a plurality of radially expanding projectiles;
- and
- wherein the liner pattern includes a repeating pattern which reduces spoking in the post-detonation fragmentation pattern.
A machine readable medium comprising a plurality of instructions that, in response to being executed on a computing device, cause the computing device to carry out a method, the method comprising:
- designing an approximately cylindrical liner having an outside surface and a longitudinal axis that runs down the center of the cylinder, wherein the cyclindrical liner includes a forward bulkhead attachment, an aft bulkhead attachment and a cavity which accepts an explosive;
- and
- selecting and applying a liner pattern to the liner, wherein the liner pattern forms, when the explosive is detonated, a post-detonation fragmentation pattern having a plurality of radially expanding projectiles;
- and
- wherein the liner pattern includes a repeating pattern which reduces spoking in the post-detonation fragmentation pattern .
