A radial (centrifugal) propulsion system based on fluids in motion, such as of hydro wind generators, which is characterized at least by: a) a circular wing (11) (ringwing) -with a frustoconical shape- the leading edge and the trailing edge of which(perimeter of small and large base of the cone, respectively) define its airfoil chord (straight side length of the cone), which forms with the plane of the small base an angle (÷), which defines the slope of the circular wing (11) and b) a main radial flow (15) over the circular wing (11) which forms with the airfoil chord at the leading edge of the circular wing (11) an angle of attack () -larger than 0 and smaller than 90 degrees, in particular larger than 8 degrees- and which due to the Coanda effect is curved depending on the angle of attack () and is produced by c) at least one centrifugal propeller (12), which by its blades -which are distributed at a suitable angle in relation to its radius (larger than 0 and smaller than 90 degrees)- that end to the leading edge of the circular wing, transforms a part of the power of the flow to mechanical power and transfers it to a rotor (20) (e. g. an electric current generator). |
