<p>Wind Turbines mainly are of two types: vertical axis(VAWT) and horizontal axis(HAWT). HAWTs are the most common type of wind turbines built across the world. VAWT is a type of wind turbine which has two or three blades and in which the main rotor shaft runs vertically. They are however less frequently used as they are not as effective as HAWT. The main difference between the VAWT and HAWT is the position of blades. In HAWT, blades are on the front spinning in the air while in VAWT, blades are wrapped around the shaft. The main advantage of VAWT over HAWT is it's insensitivity to wind direction and therefore can be mounted closer to the ground making it effective for home and residential purpose. The concept of this invention is combining both HAWT and VAWT to be said as CWT (COMPOUND WIND TURBINE) which is achieved through the proper gearing system to get more power output.</p> |
