Wind Mill Turbine

Use of wind turbine is one of the oldest methods of harnessing energy from wind to pump water. However majority of the wind mill available in the market are Aerodynamic wind mills. These types of wind mill require high cut-in speed (minimum wind speed requires for starting, i.e about 12 to 15 km/hr) and this is a major limitations for majority of the Indian geographical area except coastal area. It also requires high maintenance and very expensive also. The wind mill designed by Md. Mehtar D Hussain and Mustaq Ahmad is very innovative and unique in nature. It is not aerodynamic but it is a DRAG TYPE low height wind mill for lifting ground water.

Technical Specification:

a cIt starts at very low wind speed (i.e about 8 to 10 km/ hr), very easy to use and maintain and cheap compared to conventional aerodynamic wind mill.

a cInstead of gearbox (as used in conventional wind mill), for the conversion of rotary motion to reciprocating motion, crank mechanism is used.

a cTurbine blades are made of light weight material.

a cFurling tail mechanism & manual brake system is provided to safe guard it against the high wind velocity.
