Abstract

The present disclosure relates to the active initiation of incident energy-dissipating material from a structure surface coating as a counter measure response for the protection of a structure surface. The active initiation is triggered at a predetermined area or areas on a targeted structure surface in response to incident directed energy sensed on a target surface.

First claim

What is claimed is:

1. A coating for protecting a structure against damage from incident directed energy comprising:
a base layer comprising an adhesive layer;
at least one reactive layer comprising an incident energy-dissipating material;
a reflective layer disposed between the base layer and the reactive layer;
a sensing layer comprising an active electronic sensor, said sensing layer configured to sense incident directed energy;
a triggering mechanism in communication with the sensing layer;
an enclosure, said enclosure further comprising a contained amount of the incident energy-dissipating material, said enclosure in communication with the sensing layer and the triggering mechanism;
wherein at least a portion of the contained amount of the incident energy-dissipating material is configured to be released from the enclosure to a predetermined distance away from the coating when incident directed energy directed to the coating is sensed by the sensing layer and the triggering mechanism is activated; and
wherein the incident directed energy does not contact the incident energy-dissipating material before the release of the incident energy-dissipating material from the enclosure.

2. The coating of claim 1 , wherein the incident energy-dissipating material comprises materials selected from the group consisting of: nano-particles, micro-particles, macro-particles, ablative particles, and combinations thereof.

3. The coating of claim 1 , wherein the incident energy-dissipating material comprises an ablative matrix, said ablative matrix comprising particles that are configured to be released from the coating in a substantially uniform manner.

4. The coating of claim 1 , wherein the incident directed energy is energy from a lightning strike.

5. The coating of claim 1 , wherein the reactive layer comprises a nano-thermite-containing compound, and the reflective layer comprises a metal or a non-metal.

6. The coating of claim 1 , wherein the reactive layer comprises a metal selected from the group consisting of: gold, indium, silver, aluminum, titanium-nitride, titanium carbide and combinations thereof.

7. The coating of claim 1 , wherein the triggering mechanism is configured to activate the amount of incident-energy containing material.

8. The coating of claim 1 , wherein the coating further comprises a topcoat layer and an adhesive layer.

9. The coating of claim 1 , wherein the coating further comprises an enclosure, wherein at least a portion of the enclosure is configured to release from the coating prior to activating a predetermined amount of incident energy-dissipating material.

10. The coating of claim 1 , wherein the coating is an applique, said applique comprising a base film, said applique further comprising a top coat layer.

11. The coating of claim 1 , wherein the incident-energy dissipating material comprises components that are dimensioned to at least partially dissipate incident directed energy wavelengths.

12. The coating of claim 1 , wherein the coating comprises an average thickness ranging from about 0.01 μm to about 5,000 μm.

13. The coating of claim 1 , wherein the coating comprises molybdenum disulfide in an amount from ranging from about 10 to about 90 weight percent of applique base film.

14. A structure comprising:
a coating for protecting the structure against damage from incident directed energy, the coating comprising:
a base layer comprising an adhesive layer;
at least one reactive layer comprising incident energy-dissipating material;
a reflective layer disposed between the base layer and the reactive layer;
a sensing layer comprising an active electronic sensor, said sensing layer configured to sense incident directed energy;
a triggering mechanism in communication with the sensing layer;
an enclosure, said enclosure further comprising a contained amount of an incident energy-dissipating material, said enclosure in communication with the sensing layer and the triggering mechanism;
wherein at least a portion of the contained amount of the incident energy-dissipating material is configured to be released from the enclosure to a predetermined distance away from the coating when incident directed energy directed to the coating is sensed by the sensing layer and the triggering mechanism is activated; and
wherein the incident directed energy does not contact the incident energy-dissipating material before the release of the incident energy-dissipating material from the enclosure.

15. The structure of claim 14 , wherein the incident energy-dissipating material comprises an ablative matrix, said ablative matrix comprising particles that are configured to be released from the coating in a substantially uniform manner under high power laser illumination.

16. The structure of claim 14 , wherein the incident directed energy is energy from a lightning strike.

17. The structure of claim 14 , wherein the structure is a stationary structure.

18. The structure of claim 14 , wherein the structure is a vehicle.

19. The structure of Claim 18 , wherein the vehicle is selected from the group consisting of: manned aircraft; unmanned aircraft; spacecraft; satellites; terrestrial vehicles; surface water borne vehicles; and sub-surface water borne vehicles.

20. The structure of claim 14 , wherein the incident directed energy has a power density ranging from about 10W/cm 2 to about 10,000 W/cm 2 .
