A high-efficiency airfoil for VAWT is shown to demonstrate an increased power coefficient of higher than 0.4 due to increased lift at lower angle of attacks (AOA). The high efficiency airfoil of the present invention includes a modification to the leading and trailing edges, resulting in an improved power coefficient at higher AOAs. For the leading-edge modification, a cylindrical nose was placed at the leading edge, and for the trailing edge a scorpion tail was added to the trailing edge with angles at 20 degrees in either positive (CCW) or negative (CW) direction. The results of these modifications were compared with the corresponding results for the baseline model to illustrate their impacts on the lift and drag coefficients.

A linear network of wind turbine blade arrays has a plurality of wind turbine blade arrays. Each of the wind turbine blade arrays has a frame with a top structure and a bottom structure.

The application provides a wind power generation system. The application discloses one or several set of power generation units, which generate power by driving the power generation units through the airflow generated by the natural environment or the carrier device, and then the control module outputs the power to the power storage device, and then supplies power to each power-consuming equipment by the diverter connected to the power output terminal of the power storage device, respectively. The internal structure of a turbofan blade of this application has a cavity for repeated impact of airflow, which can utilize a single inlet air to generate several drives to the blades, so that tiny wind can provide more stable power supply for various power-consuming facilities, and the power generation system of this application is less affected by external environmental factors.

A vertical-axis wind turbine (VAWT), such as a Savonius-type VAWT, having one or more stages of curved blades rigidly mounted to a vertical axle and a structure rotatably mounted to the vertical axle. The structure has a deflector plate and a tail plate that orients the structure with respect to the blade-axle assembly such that the deflector plate is positioned upwind to deflect at least some of the wind away from the convex back faces of the curved blades, thereby increasing the force difference of the wind on the blades' concave front faces and convex back faces and therefore increasing the rotational force applied by the blades to the vertical axle. When connected to an electricity generator, the VAWT can generate electricity at a greater rate than analogous conventional VAWTs.
