Description

{APPARATUS FOR PHOTOGRAPHING MODEL SHIP}

The present invention relates to a model line photographing apparatus.

Typically, the model line test facility uses a towing carriage to measure the hydrodynamic force acting on the model line while moving the model line in the tank, or to observe and measure the flow phenomenon around the model line. . For example, the resistance acting on the hull, the wave shape at the bow site, and the water flow at the stern area can be observed.

Korean Patent Laid-Open Publication No. 2011-0115224 (hereinafter referred to as " prior art ") discloses a technique in which an underwater camera is installed just below a model line, .

However, the prior art is limited in that only the bottom of the model line can be photographed because the camera is installed in the water. Also, since the camera moves with the model line in the water, it is difficult to completely block the flow disturbance, which can affect the precise measurement of the model line test.
