Abstract
한국형 기동헬기(KUH) 다기능시현기(MFD)는 임무/시현계통을 구성하는 장비로서, 항공기 운용 중에 임무컴퓨터(MC)로부터 영상정보(항법, 비행, 생존, 전자지도 및 정비 관련 정보)를 입력받아 시현한다. 이러한 다기능시현기는 조종사가 임무를 수행하는데 있어 핵심적인 장비이며, 시현화면 제어 기능, 데이터 시현 기능, 자체진단 기능, 밝기조절 기능을 가지고 있다. 본 논문에서는 다기능시현기의 이상시현(MFD 4 Flickering) 현상이 발생한 원인을 분석하고, 이 현상에 대한 설계 개선사항을 정리하였다. 또한, 설계 개선사항에 대한 체계 안전성 분석 결과와 비행/지상시험 검증 결과를 함께 기술하였다. Multi Function Display(MFD) of Korean Utility Helicopter(KUH) is the component of mission management/display control system and displays image information(navigation, flight, survivability, digital map, maintenance) acquired from Mission Computer(MC) while the aircraft is operated. It is an essential equipment for pilots to perform flight mission and it has functions of display scene control, data display, built in test(BIT) and brightness control. In this paper, it is analyzed the cause of abnormal display(flickering) on MFD and summarized the design changes to solve the defect. It is also described system safety analysis and suggested verification results of flight/ground test.
