Abstract
A rotor for a wind energy turbine includes a hub defining an inner space and at least one rotor blade defining an inner space and having a tip and a root attached to the hub. The inner spaces of the hub and the at least one rotor blade are in fluid communication. The rotor further includes air flow means for causing air to flow out of the hub and into the at least one rotor blade.
