Outline of Final Research Achievements

The estimation method of full-scale ship propeller torque in external forces was developed. The rudder effectiveness and speed correction that ensures full-scale similar model ship motion was enhanced to apply to propeller reversing condition. The continuous operation limit of an engine was modeled and the algorithm that makes the rudder effectiveness and speed correction capable to incorporate any engine model was constructed.
The wind loads simulator was developed for free-running model ship tests in wind and waves that had been impossible so far. Free-running model tests in wind and waves and the estimation method of fluctuating full-scale propeller torque developed in this research demonstrated how the ship motion depends on the engine limit and how full-scale propeller torque differ from model-scale propeller torque.
