Abstract
A kinetic hydro energy conversion system having a turbine for mounting in a hydro energy source, wherein the turbine comprises a rotor having conformal blades and a screen for horizontally deflecting debris from the blades.
Claims11
In a kinetic hydro energy conversion system having a turbine with a rotor including a cylindrical hub and blades having one end fixed to the hub, wherein the rotor rotates about an axis of rotation corresponding to the central axis of the hub, wherein each blade has an airfoil profile at any section thereof between the ends of the blade with a twist angle and chord length defined in accordance with Glauert equations, the improvement wherein the airfoil profile for each blade section disposed at a distance from the axis of rotation lies on the surface of a cylinder having its center at the axis of rotation and its radius equal to said distance from the axis of rotation, whereby the airfoil profiles will be aligned with the direction of rotation motion of the blades.
A method of producing blades for a kinetic hydro energy conversion turbine rotor comprising the steps of:
- determining a plurality of initially planar airfoil profiles to be disposed at different distances from the axis of rotation of the rotor, with each profile having a twist angle and chord length defined in accordance with Glauert airfoil equations;
- conforming each airfoil profile onto the surface of a cylinder having its center at the axis of rotation and its radius equal to the distance of the profile from the axis of rotation;
- and forming the outer surface of the blade according to the conformed profiles;
- whereby the airfoil profiles of the resulting blade will be aligned with the direction of rotating motion during use.
