초록

본 논문에서는 저수심 구역 운항 시 추진기 손상 및 해상 부유물 걸림이 최소화될 수 있는 소형 고속선박들의 추진기에 대한 연구를 수행하였다. 검토대상 추진기들의 일반적인 특징은 정성적인 평가를 하였고, 저수심 운용성을 고려한 항해가능 수심은 일반배치를 통한 정량적인 검토를 수행하였다. 또한 선박의 기본적인 성능인 추진기별 속력성능 측면은 전산유체역학(CFD)을 통하여 저항을 해석한 후, 추진기별 추진효율을 적용하여 정량적인 속력 대 소요마력을 확인하였으며 추진기별 정성적 측면과 정량적 측면을 종합정리하여 저수심 운용을 위한 최적의 대안 추진기를 제시하였다.

Abstract

In this paper, a study was conducted on the propellers of small high-speed ships that can minimize damage to the propellers and jamming of floating objects at sea when operating in low-water areas. The general characteristics of the propellers subject to review were qualitatively evaluated, and the navigable water depth considering low-water operability was quantitatively reviewed through general arrangement. In addition, the speed performance of each propeller, which is the basic performance of the ship, was analyzed for resistance through computational fluid dynamics (CFD), and then the propulsion efficiency for each propeller was applied to confirm the quantitative speed vs. horsepower required. Qualitative and quantitative aspects for each propeller were examined. was comprehensively summarized and presented as an optimal alternative propulsion device for low-water operation.
