Abstract

Launch and recovery system(LARS) is required to perform an USV-based underwater exploration. Through the analysis of the requirements according to the scenario of underwater exploration, the mechanism of LARS and the conceptual design of the mechanical parts of LARS are carried out. In addition, a USV motion can be induced due to environmental disturbances such as waves, so the detailed design of LARS for recovering the underwater tow-fish stably in consideration of the USV motion is performed. To verify the performance of launch and recovery operations, LARS and test bed were developed. The results show that the proposed LARS can stably launch and recovery an underwater tow-fish.

무인수상정에서 수중탐색임무를 수행하기 위해서는 자동으로 수중탐색장비 진수 및 회수를 할 수 있는 진회수시스템(LARS; launch and recovery system)이 필수적이다. 수중탐색 운용시나리오에 따른 LARS 요구사항 분석을 통하여 기본적인 구동 메커니즘 및 기구부 개념설계를 수행하였다. 또한 해상에서 무인수상정은 파도와 같은 환경적인 외란에 의해 동요하게 되므로, 이러한 해상상태에 의한 외란을 고려하여 안정적으로 수중탐색장비를 회수하기 위한 상세설계와 제작을 수행하였고, 설계된 LARS에 대하여 수조시험을 통해 진회수 성능을 검증하였다.
