Document Type and Number:
WIPO Patent Application WO/2017/078194
Kind Code:
A1
Abstract:
The present invention is to provide an underwater moving apparatus with an enhanced maneuvering performance. The underwater moving apparatus with an enhanced maneuvering performance, according to the present invention, comprises: a moving apparatus body having a propeller; a plurality of long grooves formed on an outer surface of the moving apparatus body in the longitudinal direction of the moving apparatus body; a plurality of ridges which are movably installed in the inner and outer directions by being disposed on the long grooves of the moving apparatus body in the longitudinal direction of the moving apparatus body so as to protrude from the outer surface of the moving apparatus body; a ridge driving device installed in the moving apparatus body to move the plurality of ridges so as to protrude from the outer surface of the moving apparatus body; and a controller which controls the ridge driving device to prevent flow separation in the moving apparatus body by forming an eddy flow on the outer surface of the moving apparatus body in such a manner that the ridges protrude from the outer surface of the moving apparatus body when the angle of attack of the moving apparatus body becomes greater than a certain angle during underwater movement of the moving apparatus body.
