BLIND-TYPE DOOR FOR THE BOW THRUSTER

摘要

PURPOSE: A blind shape door for reducing the resistance of a bow thruster entrance is provided to reduce the degradation of the speed of a ship by minimizing vortex generation by closing the blind shape door while a bow thruster is not used. CONSTITUTION: A blind shape door for reducing the resistance of a bow thruster entrance comprises a perforation path which is horizontally formed on a boss part(1) of a ship, a propeller(30) which is vertically installed within the perforation path, a grid(20) which is respectively installed in both side of a thrust generator toward an opening inner side of the perforation path of the ship outside, and a half-opening door(100) which is installed on the inlet part of the opening in the ship outside. The propeller is respectively installed toward the left and the right. The grid prevents that foreign material is flown in the perforation path and reduces resistance by blocking the rapid water flowing.
