Vane wheel oar

The invention relates to a turbine oar, and consists of an oar disk, an oar blade and an oar hub; wherein, the structural connection is that the oar hub is arranged in the center of the oar disk; the oar blade is fixed on and connected with the oar hub; the radius of the oar disk is bigger than that of the oar blade; a narrow gap keeps between the oar blade and the oar disk, and are not contacted with each other directly; the oar blade and the oar disk can rotate around the oar disk; the oar blade is a narrow and long streamline thin sheet, the middle of which is raised moderately towards the rotary direction; the frond edge of the oar blade is a smooth surface extending from an oar rood to an oar tip; the smooth surface is vertical or almost vertical to the oar disk; when the oar blade is rotating, the smooth surface squeezes a fluid body to move along the oar disk in radial direction, while the fluid body on the other side of the oar disk is not accelerated, so that the oar disk can get strong pulling force
