Abstract

An armor system and method for the protection of an environment. The armor system includes at least one, and generally a plurality of flexible strands, a first strand support system, and a control subsystem. The control subsystem is configured to manually or automatically adapt the configuration of the armor system in response to a ballistic threat. The armor system may further include at least one of a drift gap and a spall catcher positioned between the flexible strand and the environment to be protected. The configuration can include activating a wave shape along the flexible strand. The configuration can include multiple layers of the flexible strands. The flexible strands may be implemented as a curtain. The strands may be deployed into an open-top container.

First claim

What is claimed is:

1. An armor system for the protection of an environment ( 50 ), the armor system comprising:
at least one flexible strand ( 102 ), wherein the flexible strand comprises a first end, a second end, and a strike face;
a first strand support subsystem ( 110 ) mounted to the environment and comprising at least one of an idler pulley ( 180 ) and a spool ( 184 ), wherein the first strand support subsystem retains the first end of the strand, and the flexible strand is configured to intercept a ballistic threat ( 70 ) at the strike face;
a control subsystem ( 120 ) coupled to the first strand support subsystem and configured to manually or automatically adapt the configuration of the armor system in response to the ballistic threat; and
an open-top container ( 190 ), wherein the open-top container is mounted to the environment and has a closed bottom ( 192 ), an open top region ( 194 ), and an internal box thickness (BT);

wherein, the flexible strand is deployed into the open-top container via the open top region, and when the second end of the flexible strand encounters the closed bottom, the flexible strand folds upon itself to an accordion shape as constrained by the internal box thickness.

2. The armor system of claim 1 , wherein the armor system further comprises at least one of a drift gap ( 174 ) and a spall catcher ( 176 ) positioned between the flexible strand and the environment where the armor system is implemented.

3. The armor system of claim 1 wherein, the flexible strand comprises at least one of a roller, leaf, or hinge link chain or a flexible belt having at least one armor plate ( 170 ) that is attached to the flexible belt.

4. The armor system of claim 1 wherein, the armor system further comprises a second strand support subsystem mounted to the environment, wherein the second strand support subsystem retains the second end of the flexible strand.

5. The armor system of claim 4 , wherein the control subsystem ( 120 ) is further coupled to the second strand support subsystem.

6. The armor system of claim 1 , wherein the configuration of the armor system includes activating a wave shape along the flexible strand.

7. The armor system of claim 1 , wherein the flexible strand is looped around the at least one of the idler pulley and the spool to present two or more layers to the threat.

8. A method for defeating a ballistic threat, the method comprising:
attaching a first strand support system ( 110 ) to an environment ( 50 ) to be protected, the first strand support system comprising at least one of an idler pulley ( 180 ) and a spool ( 184 ); and
operating the first strand support system to retain at least one flexible strand ( 102 ) at a first end thereof to provide an armor system, wherein the flexible strand further comprises a second end, and a strike face; and, wherein the flexible strand is configured to intercept a ballistic threat ( 70 ) at the strike face;
wherein the armor system further comprises a control subsystem ( 120 ) that is coupled to the first strand support subsystem, and the control subsystem configured to manually or automatically adapt the configuration of the armor system in response to the ballistic threat; and
wherein the armor system further comprises an open-top container ( 190 ) mounted to the environment and having a closed bottom ( 192 ), an open top region ( 194 ), and an internal box thickness (BT); wherein, the flexible strand is deployed into the open-top container via the open top region, and when the second end of the flexible strand encounters the closed bottom, the flexible strand folds upon itself to an accordion shape as constrained by the internal box thickness.

9. The method of claim 8 , wherein the armor system further comprises at least one of a drift gap ( 174 ) and a spall catcher ( 176 ) positioned between the flexible strand and the environment.

10. The method of claim 8 wherein, the flexible strand comprises at least one of a roller, leaf, or hinge link chain or a flexible belt having at least one armor plate ( 170 ) that is attached to the flexible belt.

11. The method of claim 8 wherein, the armor system further comprises a second strand support subsystem that is mounted to the environment, wherein the second strand support subsystem retains the second end of the flexible strand.

12. The method of claim 11 , wherein the control subsystem ( 120 ) is further coupled to the second strand support subsystem.

13. The method of claim 8 , wherein the configuration includes activating a wave shape along the flexible strand.

14. The method of claim 8 , wherein the flexible strand is looped around the at least one of the idler pulley and the spool to present two or more layers to the threat.
