PURPOSE: A ship propulsion device using the compressed air from the middle of a propeller is provided to improve the propulsion efficiency by a gas spray part and the propeller. CONSTITUTION: A cavity(120) is formed on a shaft(110) of a propeller(100) in the axial direction. A gas jet unit sprays gas through the cavity. An air inhale unit inhales the air from the outside of the ship. An air compressor unit compresses the inhaled air of the air inhale unit. The compressed air supply unit supplies the compressed air of the air compressor unit to the gas jet unit. The compressed air from the center of the propeller produces the driving force and makes synergistic effect of propeller. The high propulsion efficiency is made by using the compressed air. |
