LCT에서 선박용 상호반전 전후 프로펠러 상호작용 특성 시험적 연구

Abstract

In order to develop test technique for CRP propulsion, CRP dynamometer which can be installed inside the model ship was designed and manufactured and then the research ship was selected. To begin with, we checked the performance of the CRP dynamometer through the calibration and then installed it inside the model ship. After the model ship setup including a CRP and a rudder in the Large Cavitation Tunnel(LCT), A series of model test composed of propeller behind wake(PBW), cavitation observation and pressure fluctuation tests was conducted. Through the model test and data analysis for CRP, the performance of the CRP dynamometer was verified and the experimental technique was established. dynamometer through the calibration and then installed it inside the model ship.
