Due to its unmanned feature and some of being matured underwater technologies, UUV(Unmanned Undersea Vehicle) is increasingly considered as a utility player in today's battle-field. The operational benefit of submarine-based UUV operation could be enormous yet the integration challenges are significant, particularly for most of small conventionally-powered submarines. In this paper, we consider UUV operational methodology via the conventional submarine's torpedo tube. Two previous attempts having been done to retrieve the UUV through torpedo tube are reviewed, and their pros and cons are also analyzed. Then, an alternative option is proposed for UUV operation via torpedo tube. In addition, some of practical challenges are also discussed in the paper.

대표적인 잠수함 발사 유도탄의 수중에서의 발사 개념에 대한 기술 동향을 분석하였다. 세계 각 국의 수중 발사 유도탄 중 발사 형태가 특히 다른 Tomahawk, Sub Hapoon, Exocet SM39 유도탄에 대하여 그 발사 방법에 따른 기술 동향과 장단점을 비교 분석하였다. 대표적인 서방 세계 수중 발사 유도탄인 Tomahawk는 여러 가지 다른 형태가 있지만 잠수함 발사는 Wet Capsule에 의해 보호되며 어뢰 발사관을 이용하여 압축수에 의해 수중으로 배출되는데 잠수함과의 안전거리에서 견일줄이 유도탄 진행에 따라 장력을 발생 부스터를 점화시킨다. 이 부스터에 의해 수면까지 부상하며 부스터에 설치되어 있는 수중궤적 제어용 Jet-Tab이 수중운동을 제어한다. 수면에서 부스터의 추진력에 의해 대기로 진입하는데 일정속도 이상으로 가속된 후 부스터를 분리시키며 Turbo 엔진이 점화되어 계속 비행하게 된다.(중략)

Purpose: The purpose of this study is to improve submarine TACM launcher system safety device performance. Methods: In this study, EPLD(Electrically Programmable Logic Device) control and time sharing method to the safety device actuator motor and discrete signal processor in launch control panel were used to resolve unusual performance of safety system. Results: The result of this study are as follows; First, sporadic stopping of safety device actuator motor due to insufficient In-Rush current was resolved. Second, repeat of safety device condition as lock & release due to chattering for motor activating was resolved. Third, simultaneous release function for safety device actuator was available. Conclusion: The unusual performance of function for submarine TACM launcher system was overcame by applying EPLD control and time sharing method. The suggestions were proved by performance test in the pressure chamber. The results of this study enhanced survivability of ${\bigcirc}{\bigcirc}{\bigcirc}$ class submarine from enemy torpedo.
