  • Patent number: 10151302
    Abstract: Exemplary compact wind power generation systems are configured to be suitable for residential and other locations where concealed moving parts are desirable. The wind power generation systems utilize a propeller disposed behind a contracting inlet. The propeller blades may be oriented “into the wind” to develop consistent torque across a variety of wind speeds. The propeller may rim-drive power generation components, further reducing vibration, or may share a common rotational axis with the power generation components.

  • Patent number: 10151296
    Abstract: A blade for a wind turbine defines an airfoil with a leading edge section and a trailing edge section, notably a flat-back trailing edge. A rounded connecting section interconnects a pressure side section of the airfoil and the trailing edge section. The rounded connecting section attaches to the pressure side section at a transition point, in which the pressure side section's tangent does not coincide with the rounded connecting section's tangent, so that the outer surface of the airfoil has a sharp corner at said transition point. The truncated radius, i.e. geometrical discontinuity, thus formed at the transition between the pressure side section and the trailing edge section increases the aerodynamically effective surface of the pressure side and enables forced and hence controlled flow separation without compromising ease of manufacture and structural stability of a fiber-reinforced structure making up a shell of the blade.
