An embodiment of the present invention provides a system and a method to test mechanical stress which is applied to a sealant (206) from lightning which strikes an aircraft. According to an embodiment of the present invention, the system comprises: a sample (204); a test fixture (210); and a capacitor (212). The sample (204) comprises: an electrically nonconductive sealant (206) for a fuel tank of an aircraft which is in a cylindrical shape; and an electrically conductive wire (208) whose center is fixated in an axial direction within the sealant. The text fixture (210) fixates the sample (204) during a test. The capacitor (212) is electrically combined with the test fixture (210) and tests a lightning, which strikes the aircraft, by gasifying the wire (208) with an electric current to generate a mechanical impact on the sealant (206).

    여기에 기재된 실시예는, 항공기에 내리치는 번개로부터 실란트(206)에 인가되는 기계적 스트레스를 모의하기 위한 장치 및 방법을 제공한다. 일 실시예는 시료(204), 테스트 픽스처(210) 및 캐패시터(212)를 구비한다. 시료(204)는, 원통 형상을 갖는 항공기 연료 탱크용의 전기적으로 비도전성의 실란트(206)와, 실란트 내에서 축방향으로 중심이 맞춰진 전기적으로 도전성의 와이어(208)를 포함한다. 테스트 픽스처(210)는 테스트하는 동안 시료(204)를 고정한다. 캐패시터(212)는, 테스트 픽스처(210)에 전기적으로 결합되어, 실란트(206)에 기계적 충격을 발생시키기 위해 전류로 와이어(208)를 기화시킴으로써 항공기에 내리치는 번개를 모의한다.
