<p>Disclosed herein is a rotator-type propulsion apparatus in which a hub, blades, a propeller opened at a front side thereof and having a sucked fluid passage, and a duct having a plurality of accelerating suction parts formed thereon are integrally formed so as to rotate together. Particularly, the present invention allows the fluid sucked into the ducts through a plurality Accelerating suction parts formed on the outer peripheral surface of the ducts to continue to join the fluid introduced into and flowing inside the fluid propulsion apparatus when rotating at a high speed. In addition, the present invention provides an super high-speed fluid propulsion apparatus in which a trumpet-shaped duct is interposed between the blades of the propeller, so that the flow speed of the fluid introduced into the blades is accelerated within a plurality of trumpet-shaped ducts partially nested within one another.</p> |
