Hardware in the loop experiments with ship propulsion systems in the towing tank: Scale effects, corrections and demonstration

Standards for environmental impact, safety and operational performance of ships are becoming increasingly strict. In order to meet these standards, the new ship designs must be predicted with an increasing level detail confidence. As present prediction methods lack realistic, dynamic behaviour ship's propulsion plant, there is a need more advanced methods. this paper, open water test Hardware in Loop (HIL) functionality proposed. HIL tests combine software hardware components emulate realistic plant towing tank. It known, however, that experiments tank subject viscous scale effects. addition this, shaft dynamics distorted by number effects occurring inside model system. it demonstrated measurements if corrections applied, interaction between propeller simulated engine system can accurately emulated basin.
