Wind effect simulation system in model tests of ship manoeuvrability

S 2

64--67

Dependence on hydro-meteorological conditions in the test area is an “Achilles’ heel” of physical experiment used for assessment of ship manoeuvrability. Aerodynamic forces and moments generated on the ship upperworks distort significantly the measured values. The paper presents new testing tool in the form of physical simulation of wind effect enabling quantitative evaluation of distortion of the measurement results. Another feature of the system enabling compensation of real atmospheric conditions prevailing during the experiment is also presented. The wind effects simulation arrangement includes board data acquisition and processing system, automatic control system and executive system consisting of industrial fans.
