초록

헬리콥터 호이스트는 응급구조 및 해상작전 등 다양한 임무에 활용되는 핵심 장비이나, 안전성은 단순한 정격하중 충족만으로 확보되지 않는다. 본 연구는 소해헬기 적용을 중심으로 대표 사고사례, 감항개선지시, 장비 단품기준 및 체계 장착기준을 종합적으로 검토하여 해상 운용 호이스트의 감항 요구와 설계 안전성 쟁점을 분석하였다. 분석 결과, 호이스트의 안전성은 구조강도뿐 아니라 과부하 보호장치의 신뢰성, 케이블 및 훅 계통의 건전성, 장착 적합성, 운용 제한, 지속감항 관리가 함께 확보될 때 성립하며, 특히 해상환경에서는 파랑, 조류, 하강풍, 수면운동 및 반복 진수·회수 운용에 따라 케이블 편각과 장력 변동이 증가하므로, 이를 반영한 통합적 감항평가와 운용 제한 설정이 필요함을 확인하였다.

Abstract

Helicopter hoists are critical mission equipment for rescue, medical evacuation, and maritime operations, but their safety cannot be assured solely by satisfying rated load requirements. This study analyzes the airworthiness requirements and design safety issues of helicopter hoists for maritime mine countermeasure applications, with emphasis on mine countermeasure helicopters. Representative accident cases, equipment-level qualification standards, installation-level criteria, and maritime operational characteristics were reviewed. The results show that hoist safety is governed not only by structural strength but also by overload protection reliability, cable and hook system integrity, installation suitability, operational limitations, and continued airworthiness management. In maritime operations, waves, currents, rotor downwash, sea-surface motion, and repetitive short deployment cycles can increase cable angle, load fluctuation, and cable degradation. A preliminary assessment indicates that safety margin decreases as cable angle increases under conservative maritime assumptions. Therefore, maritime hoist airworthiness should be assessed through an integrated approach combining equipment qualification, installation criteria, and mission-specific operational limitations.
