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 method for protecting a structure against damage from incident directed energy comprising:
locating a coating at predetermined locations on a structure surface, the coating comprising a sensing layer comprising an active electronic sensor, and an enclosure, said enclosure further comprising a contained amount of an incident energy-dissipating material, the enclosure in communication with the sensing layer and a triggering mechanism;
sensing incident directed energy at the sensing layer by the active electronic sensor, said active electronic sensor in communication with the triggering mechanism;
activating the triggering mechanism;
actively triggering an amount of the incident energy-dissipating material for release of the amount of incident energy-dissipating material from the enclosure at predetermined locations on the structure surface; and
releasing the triggered amount of the incident energy-dissipating material from the enclosure to a predetermined distance away from the structure surface;
wherein the incident directed energy does not contact the incident energy-dissipating material before release of the incident energy-dissipating material from the enclosure.

2. The method of claim 1 , wherein the enclosure is selected from the group consisting of an applique, a container, a layer in the coating, and combinations thereof.

3. The method of claim 1 , wherein the coating comprises the sensing layer, the triggering mechanism and the amount of incident energy-dissipating material.

4. The method of claim 1 , wherein the enclosure comprises layers selected from the group consisting of: a reflective layer, a base layer, an adhesive layer, a top coat layer, and combinations thereof.

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

6. The method 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.

7. The method of claim 1 , wherein the enclosure is located remotely from a point of sensed incident direct energy on the structure surface.

8. The method of claim 1 , wherein the structure is selected from the group consisting of a vehicle, an aircraft, and a stationary structure.

9. A system for protecting a structure against damage from incident directed energy, said system comprising:
a coating applied to predetermined locations on a structure surface, said coating comprising a sensing layer, said sensing layer comprising and in communication with at least one sensor;
at least one enclosure containing an amount of incident energy-dissipating material in the enclosure, said enclosure in communication with the sensing layer, and said enclosure located at predetermined locations on the structure surface; and
a triggering mechanism in communication with the sensor and the enclosure, said triggering mechanism configured to activate the amount of incident energy-dissipating material within the enclosure at predetermined locations on the structure surface; wherein the amount of triggered incident energy-dissipating material is actively released from the enclosure to a predetermined distance away from the structure surface;
wherein the incident directed energy does not contact the incident energy-dissipating material before release of the incident energy-dissipating material from the enclosure.

10. The system of claim 9 , wherein the enclosure is selected from the group consisting of: an applique, a container, and combinations thereof.

11. The system of claim 9 , wherein the coating is applied to the structure surface as an applique.

12. The system of claim 9 , wherein the coating comprises the sensing layer, the enclosure and the amount of incident energy-dissipating material.

13. The system of claim 9 , wherein the enclosure comprises layers selected from the group consisting of: a top coat layer, a base layer, an adhesive layer, a reflective layer, and combinations thereof.

14. The system of claim 9 , wherein the incident energy-dissipating material comprises material dimensioned to at least partially dissipate incident directed energy wavelengths.

15. The system of claim 9 , 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.

16. The system of claim 9 , wherein at least a portion of the enclosure releases from the structure prior to activating a predetermined amount of incident energy-dissipating material.

17. The system of claim 9 wherein the enclosure is located remotely from a point of incident direct energy on the structure surface.

18. The system of claim 9 , wherein the structure is selected from the group consisting of: a vehicle, an aircraft, and a stationary structure.
