摘要
The invention relates to the field of shipbuilding, and more specifically, to the experimental fluid mechanics and relates to the scale models icebreakers and ice ships for hydrodynamic tests in towing tanks of ice. Tasks utility model: - improving the efficiency of the hydrodynamic test models icebreakers and ice ships with mines of the bottom and / or sliding devices; - testing without the need for expensive experimental equipment. This is achieved by the fact that in a large-scale model of the ship to carry out hydrodynamic tests in the towing tank of the ice from the bottom of the bottom shaft is made of a transparent material. Hold-shaft can be closed closure made of a transparent material, or it the retractable device can be installed. The proposed model allows the vessel to carry out visual observation and capture on photo and / or video camera, attached directly on the model, the interaction of broken ice to the bottom of the vessel, with the bottom shell shafts and / or sliding devices, which increases the efficiency of the test, reduces the need for equipping the towing tank and thereby reduces the cost of testing.
