WIPO Patent Application WO/2017/119630
Kind Code:
The present invention relates to a propulsion apparatus for a vessel of a high-speed rearward jet and integral rotation type. A high-speed rearward jet propulsion apparatus for a vessel comprises: a shaft (100) which is rotatably installed on a vessel and rotated by a driving means; a hollow main body (200) which is fixed at the rear of the shaft (10) so as to rotate integrally with the shaft; a blade part (300) having one side fixed to one side of the shaft (100) and the other side fixed to the hollow main body (200) and allowing water from outside the propulsion apparatus to flow into a water collection space (400) while rotating; and a tapered water collection space (400) formed by being surrounded by the blade part (300) and forming a narrow space at the front thereof and a wide space at the rear thereof, wherein the shaft (100), the main body (200), the blade part (300), and the water collection space (400) are integrally rotated such that the water introduced into the water collection space (400) is jetted to the rear of the main body (200) at high speed. In addition, the blade part (300) comprises at least two blades (310), in which a water inflow gap (330) is formed between the tip (310a) of one blade and the outer circumferential surface of an adjacent blade, wherein the blades (310) are of an arc or spiral shape expanding in the radial direction from a blade root (310a) to a blade tip (310b) and the blades (310) have a width which widens from the front to the rear along the axial direction when viewed in the axial direction and a conical space is formed such that the water collection space (400) is widened in the axial direction.
