초록

현재 운용 중인 선박의 추진기에는 선박의 수중음향 스텔스 성능 향상을 위해 PRAIRIE system을 적용하고 있다. 하지만, PRAIRIE system에 대한 공기분사량 조절과 수중방사소음에 미치는 기여도 분석 등의 운용성 측면에서 최적화 연구는 미흡한 수준이다. 이에, 본 논문에서는 실적함 수중방사소음 측정 결과 분석을 통해 효율적인 PRAIRIE system 운용 방안과 수중방사소음 최적화를 위한 추가 연구방향을 제시하였다.

Abstract

Currently, the PRAIRIE System is applied to the propeller of the naval ship in operation to improve the underwater acoustic stealth performance of the naval ship. However, optimization research is insufficient in terms of operability, such as controlling the amount of air injection into the PRAIRIE System and analyzing the contribution to underwater radiation noise. Therefore, in this paper, an efficient PRAIRIE system operation plan and additional research directions for optimizing underwater radiation noise were presented through analysis of the results of underwater radiation noise measurement.
