The present invention relates to a system and a method using a microsphere filled with a fluid to help monitoring and indicating a high-energy blunt impact on a structure such an air craft. A plurality of microspheres may be attached to or provided in a coating applied onto the surface of a substrate (for example, tape or applique), and the substrate may be attached to the surface of a structure to be monitored. The microsphere is designed to burst at one or more specified pressure limit values. In some embodiments, the microsphere is filled with an electrical conductive fluid, and the electrical conductive fluid changes an electromagnetic state of the substrate when the electric conductive fluid flows out of the bursting microsphere. A blunt impact indicator is generated in reaction to detection of sufficiently great change in electromagnetic state of the substrate. Thereafter, the impact point may pass through a non-destructive inspection.

    항공기와 같은 구조물 상의 고에너지 블런트 충격을 모니터링하거나 표시하는 것을 돕기 위하여 유체로 채워진 할로우 마이크로스피어를 이용하는 시스템 및 방법. 복수의 마이크로스피어가 서브스트레이트(예컨대, 테이프 또는 아플리케)의 표면 상에 적용된 코팅에 부착되거나 내장될 수 있으며, 서브스트레이트는 모니터링될 구조물의 표면에 부착될 수 있다. 마이크로스피어는 하나 이상의 특정된 압력 한계값에서 파열되도록 설계된다. 몇몇 실시예에서, 마이크로스피어는 전기 전도성 유체로 채워지는데, 이 전기 전도성 유체는 파열된 마이크로스피어로부터 유출되면 서브스트레이트의 전자기 상태를 변화시킨다. 서브스트레이트의 전자기 상태의 충분히 큰 변화의 검출에 반응하여, 블런트 충격 표시가 생성된다. 이후, 충격 지점은 비파괴 검사를 거칠 수 있다.
