About the project

Perpendicular Wind Turbines. Rising sea levels and escalating pollution levels has generated worldwide interest and has given rise to new wind turbines designs.(Check out EWICON, Bladeless windmill)

HAWT are the most common type of wind turbines built across the world. VAWT is a type of wind turbine which have two or three blades and in which the main rotor shaft runs vertically. VAWT are also called as transverse axis wind turbine / cross-flow wind turbine

Perpendicular wind turbines belongs to VAWT category, in which axis of blades run perpendicular to the flowing air or the ground and are great placement at residential sources for renewable energy

These turbines have their generator and gearbox installed close to the ground, facilitating service and repair. These turbines do not need to be pointed into the wind, eliminating wind-sensing and orientation mechanisms

To overcome the disadvantages involved in VAWT like unstability, low power generation, different technologies have been developed and experimented. Once such model is Active real-time pitch attack angle regulation technology

The core of Active real-time pitch attack angle regulation technology is to adjust blade angles on a spinning turbine. The device was tested on a 1-m tall x 1.36-m wide VAWT in a wind tunnel at a wind speed of 2 m/s.

The conversion rate of wind energy to mechanical energy reaches 68%, surpassing the limit of 59.3% by Betz Law. The measured torque was 0.9 to 1 Nm at 44 rpm

There are many more technologies and prototype experiments are being made which will lead to change the shape of current large wind turbine industry.
