Consider a wind turbine comprised of two blades, with a radiusof 63 ft., which delivers maximum power when the wind speed isabove 16 knots (18.4 mph). The wind turbine is designed to produce135 hp with an efficiency of 74%. The rotor is designed to operateat a constant speed of 45 rpm in winds over 5 knots (5.8 mph) bycontrolling system load and adjusting blade angles.
Estimate the blade speed and power coefficient for the maximumpower condition.
