Abstract
The current accepted design configuration of wind turbines across the output scale is for a horizontal axis, three bladed propeller systems, mounted on a large tower, with a housing that encompasses the gear train and power transmission components. The blades are typically aerodynamically profiled and the pitch may be adjusted in service to accommodate variable wind speeds and feathered to provide minimum wind resistance id the wind speed exceeds a critical threshold value. The entire turbineblade assembly can be rotated in order to face into the wind and optimise the efficiency of the unit, figure 1.
