PURPOSE: A propulsion device using lifting force is provided to reduce a space, in which various facilities for propulsion devices are installed, by obtaining propulsion force from lifting force caused by discharging high pressure seawater. CONSTITUTION: A propulsion device using lifting force comprises a high pressure water supply facility(12), a seawater propeller(14), and a rotating angle adjusting part(16). The high pressure water supply facility compresses seawater flowed inside a hull to high pressure. The seawater propeller is vertically installed with respect to the lower part of the hull in order to spray high pressure water supplied from the high pressure water supply facility to the outside, thereby propelling the hull. The rotating angle adjusting part adjusts rotating angle of the seawater propeller with respect to the hull. |
