Jul 04, 2017· 3. Working of Wind Pump • This helical blade vertical axis wind turbine is designed to pump the water. When air blows and strikes the blade of turbine blade starts to rotate. • Rotation of blade mainly depends upon the velocity of air and surface area of blade. The bearings which are fixed to centre shaft will smoothen the rotation.
A vertical-axis wind turbines (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

Aug 05, 2015· Abstract: In order to improve the self-starting capacity of straight-bladed vertical axis wind turbine (SB-VAWT), a prototype with collective pitch control (CPC) was developed. The pitch angle of each blade was adjusted by a blade pitch control mechanism, consisting of four driving wheels attached to the blades and one servo motor, and motion of each blade was half of the rotor.
278 Wind Power Generation and Wind Turbine Design horizontal axis machines. Another key advantage is that the mechanical load may be connected directly to the VAWT rotor shaft and located at ground level. This removes the need for a substantial tower to support the weight of equipment such as the gearbox, generator and yaw mechanism.
