초록

본 연구는 어뢰 개발의 역사적 추세를 분석하여 소형 어뢰의 설계 방향을 제시하였다. 소형 어뢰는 기존 대형 어뢰에 비해 높은 기동성과 유연성을 제공하며, 무인 수상정(unmanned surface vehicle, USV)과 결합하여 현대 해상 전력에서 중요한 역할을 수행할 가능성을 확인하였다. 길이와 직경 비율을 약 10:1로 설정하고, 총중량 대비 탄두 중량을 약 20%로 최적화함으로써 유체 저항을 줄이고 폭발력을 극대화할 수 있음을 확인하였다. 이러한 특성은 소형 어뢰가 좁은 수로, 연안 방어 및 다수 표적 대응 등 다양한 환경에서 효과적으로 활용될 수 있음을 시사한다. 본 연구는 소형 어뢰 설계의 효율성을 높이고 해상 무인체계와의 결합 가능성을 제고하는 데 기여할 것으로 기대된다.

Abstract

This study analyzes the historical trends in torpedo development to propose design directions for small torpedoes. Compared to conventional large torpedoes, small torpedoes offer superior maneuverability and flexibility, and their integration with Unmanned Surface Vehicles (USVs) suggests significant potential in modern naval operations. By optimizing the length-to-diameter ratio to approximately 10:1 and the warhead-to-total weight ratio to about 20%, the study confirms the possibility of reducing hydrodynamic resistance and maximizing destructive power. These characteristics indicate that small torpedoes can be effectively utilized in various scenarios, including narrow waterways, coastal defense, and multi-target engagement. This research is expected to enhance the efficiency of small torpedo design and promote their integration with unmanned naval systems.
