The pumpjet propulsor is composed of rotor, stator & duct which results in the strong interaction between the components. To measure the thrust and torque for duct and stator, a ring-shaped sensor was applied. The test equipment including pumpjet is installed on open-water test dynamometer and the stern of the submerged body. As the whole pumpjet including duct and stator was considered as the propulsor from pumpjet open-water test, the self-propulsion test was conducted in the same way. The total thrust, combined thrust of rotor, duct & stator was used for the pumpjet self-propulsion test analysis. Accordingly, the self-propulsion test & analysis were conducted in the same way as that of the conventional propeller. The full-scale prediction of the pumpjet propulsor made possible to evaluate the performance and get the full-scale operating conditions for the cavitation and noise tests. On the basis of the present study, it is thought that the pumpjet propulsor would be designed optimally. 20220714-01-01T00:00:00Z https://www.kriso.re.kr/sciwatch/handle/2021.sw.kriso/7697 Title: 자유항주시험 시나리오 검증을 위한 준비모형 개발 Authors: Lee, Yeong jun; 박정홍; 최진우; 윤근항 20220602-01-01T00:00:00Z https://www.kriso.re.kr/sciwatch/handle/2021.sw.kriso/7696 Title: 수중함 운항성능 추정을 위한 연구 Authors: Yun, Kunhang; 윤재문 20220602-01-01T00:00:00Z
