ICE EXPERIMENTAL TANK Russian patent published in 2012 - IPC B63B9/02 G01M10/00 F25C1/04 

FIELD: test equipment.

SUBSTANCE: invention refers to experimental flow dynamics of sea transport and deals with creation of laboratories for investigations of ice properties of ships. Ice experimental tank includes bowl with boards, handling dolly with equipment for water jets spraying at freezing of simulated ice cover. Outside the tank bowl parallel to one of its longitudinal boards there routed is a channel with the depth of not less than 0.5 m, which is interconnected with the bowl cavity via a pipeline. Perforated air supply tube to the channel is located at the channel bottom. Handling dolly is equipped with suction hydraulic pump for water supply to water jets spraying equipment, which is equipped with a connection pipe the receiving end of which is lowered into the above channel to the depth of not less than the half of its depth. Connection pipe of hydraulic pump is equipped with a rigid protective casing enclosing its housing and located so that it crosses free water surface in the channel and deepened with its lower end to the value of not less than 0.5 of the channel depth.

EFFECT: providing uninterrupted preparation of simulated ice for conducting the tests of ships models and engineering structures.
