DEVICE FOR HYDRODYNAMIC TESTS OF SURFACE VESSEL MODEL Russian patent published in 2010 - IPC G01M10/00 B63B9/02 

FIELD: testing equipment.

SUBSTANCE: invention is related to the field of shipbuilding, namely to technical means of experimental hydromechanics, and may be used for hydrodynamic tests of surface vessel model. Device comprises area of water with free surface, model of surface vessel towed by rope, motion of which is carried out through falling liquid weight that fills metering reservoir, which has holes both for reception and drain of liquid weight. Reservoir is fixed to axis of movable unit. Water to reservoir is sent through nozzle, which, together with elbow, crossbeam and bar creating bearing structure, and water pump, develop continuous water flow for reservoir filling. Fixed unit is attached to crossbeam, which produces polyspast together with unit. In process of tests performance, vessel model is positioned in the end of metering section of water area, and at the same time empty reservoir is lifted upwards. After contact with hole, reservoir after filling with liquid weight till rated level starts evenly lowering vertically down, providing for even horizontal motion of vessel model. The main result of experiment is time of weight lowering from unit down to support plate.

EFFECT: reduced cost of pool equipment, increased accuracy of performed measurements, reduced labour intensity of experiments performance.
