Warerjet 추진시험선 설계, 건조 및 실해역 성능시험

Abstract

This paper describes the design, construction and sea-trial test of a test ship with waterjet propulsion system. Local flow characteristics around an intake and nozzle of an operating waterjet propulsion system is measured at a sea to understand interaction between hull and waterjet propulsion. Flow rate is corrected by bollard pull test and shaft power is measured directly using a torsion meter. The measured results are compared with the predicted results on the basis of DB. Those experimental data will be useful for the future works to develope the model test method for powering performance prediction method.
