Claims (4)
- 연료탱크의 압력을 검출하는 압력센서,상기 연료탱크의 내부의 온도를 검출하는 온도센서, 그리고상기 온도센서에서 제1 시점에서 검출된 제1 온도와 제2 시점에서 검출된 제2 온도의 온도 변화량에 따른 제1 압력 변화량을 계산하고, 상기 압력센서에서 상기 제1 시점에서 검출된 제1 압력과 상기 제2 시점에서 검출된 제2 압력 사이의 제2 압력 변화량을 계산하고, 상기 제2 압력 변화량에서 상기 제1 압력 변화량을 감산하여 실제 압력 변화량을 계산하고, 상기 실제 압력 변화량이 기준 압력 변화량 이상이면 상기 연료탱크에 누유가 발생한 것으로 판단하는 제어부를 포함하며,상기 제2 시점은 상기 제1 시점으로부터 설정된 시간만큼 경과된 시점이고, 상기 연료탱크는 T-50 항공기의 연료탱크이고, 상기 온도센서는 상기 연료탱크의 바닥과 천상 사이의 중간 지점의 온도를 검출하는 것을 특징으로 하는 연료탱크의 누유 검사 시스템.
- 삭제
- 제1항에 있어서,상기 온도센서는 상기 연료탱크의 바닥으로부터 7.5인치 지점의 온도를 검출하는 것을 특징으로 하는 연료탱크의 누유 검사 시스템.
- 제1항에 있어서,상기 기준 압력 변화량은 0.02psig인 것을 특징으로 하는 연료탱크의 누유 검사 시스템.
