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.

A method for protecting a structure against damage from incident directed energy, the structure surface comprising a coating and at least one enclosure, the coating comprising a sensing layer, and the enclosure further comprising a contained amount of an incident energy-dissipating material, the enclosure in communication with the sensing layer and a triggering mechanism, the method comprising the steps of:

locating the coating at predetermined locations on a structure surface;

locating the enclosure at predetermined locations on the structure surface;

sensing incident directed energy at the sensing layer; and

activating the triggering mechanism, said triggering mechanism activating the incident energy-dissipating material in the enclosure at predetermined locations on the structure surface.

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.

nano-particles, micro-particles, macro-particles, ablative particles, and combinations thereof.

7. The method of claim 1, wherein incident directed energy is sensed by the sensing layer, and incident energy-dissipating material located within the enclosure at a predetermined location is activated by a triggering mechanism in communication with the sensing layer and the incident energy-dissipating material to release a predetermined amount of incident energy-dissipating material.

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

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

10. A system for protecting a structure against damage from incident directed energy, said incident directed energy having at least one wavelength, said system comprising:
