초록

군용 헬리콥터는 피탄에 의한 폭발을 방지하기 위한 OBIGGS System을 장착하고 있다. OBIGGS 경고등은 이상감지 시에만 작동해야 하나, 초도생산 과정에서 빈번하게 이상 작동을 하여 설계개선이 요구되었다. 본 논문에서는 OBIGGS 경고등 이상 점등 원인을 검토하고 개선방안을 수립 및 입증하였다.

Military helicopters are equipped with OBIGGS System to prevent an explosion caused by the projectile. OBIGGS warning lights up should only operate when sensing fault, but it frequently worked without malfunction in the initial production process and the design improvements were required. In this paper, the cause of OBIGGS abnormal warning lights up was reviewed, the improvements were established and proven.
