There are two main types of wind turbines. The two general categories for wind turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and

A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind (but not necessarily vertically) while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which removes ...

1.3 How to design a good small vertical-axis wind turbine 1.3.1 Although different from a HAWT, the core technology of a VAWT remains a wind mill structure with blades. After choosing an airfoil, it is necessary to calculate a concave orientation, angle, width, and quantity because each of these factors determines the performance of the VAWT.
· Startup wind is 3X less than any other technology, it starts operation with only 1 mph wind. · It generates 5,000W with 28mph winds – 2X the current power generated by best latest technology. · It is light and small for residential and commercial applications.
Vertical- versus horizontal-axis turbines. A major benefit of vertical-axis wind turbines (VAWTs) compared with their (upwind) horizontal counterparts (HAWTs) is that they can draw wind from all directions while not needing a yaw system. A main disadvantage compared with modern, large-scale HAWTs is much lower aerodynamic efficiency.

This paper describes the development of a novel vertical axis wind turbine used for teaching and research purposes. The device is designed to operate at low tip speed ratios and features blades that are symmetric about the mid-chord plane. The blades are actively pitched by means of a mechanical system so that the chord of each blade rotates by 180o for every revolution of the main rotor.

We present a method to adapt Greenberg's potential flow model for coupled pitching and surging flow such that it can be applied to predict the loads on a vertical-axis wind turbine blade. The model is extended to compute loads on a blade undergoing multi-harmonic oscillations in effective angle of attack and incoming flow velocity by formulating the blade kinematics as a sum of simple harmonic ...
