초록

회전익 항공기의 충돌방지등은 항공기 운용 중 충돌을 방지하기 위한 목적으로 사용되며, 비행 안전성을 확보하기 위한 핵심 구성품이다. 한국형 기동헬기(KUH)의 충돌방지등은 상부등과 하부등으로 구성되며, 충돌방지등 전원공급기와 항공기에 함께 장착되어 운용된다. 그리고 충돌방지등은 밝기 조절 및 선택적 점등이 가능한 이중 구조로 설계되었다. 항공기 납품 후 운용 과정에서 충돌방지등의 이상점 등이 발생하였고, 이러한 현상을 해소하기 위하여 항공기 체계/구성품 단위의 종합 검토를 수행하였다. 본 논문에서는 충돌방지등의 이상점등이 발생한 원인을 분석하였고, 설계 개선방안을 제시하였다. 그리고 설계 개선방안에 대한 타당성을 구성품 및 항공기 체계 지상 및 비행시험으로 입증하였다.

An anti-collision light of a rotary-wing aircraft is used for the purpose of preventing collision during the operation of an aircraft and is a key component to ensure flight safety. The anti-collision lights of the Korean Utility Helicopter (KUH) consist of upper and lower lights, and the power supply of anti-collision lights mounted on the aircraft. The anti-collision light is designed as a dual structure capable of brightness control and selective lighting. During the operation after delivery of the aircraft, abnormal lighting of anti-collision light occurred. In this paper, a comprehensive review of the aircraft system and component level was conducted to solve these phenomena at first. Then, the causes of anti-collision light anomalies were analyzed and the design changes are presented. The validity of design changes has been verified through the component and aircraft system ground/flight test.
