Abstract
A method for deicing a rotor blade having a blade root, a blade tip, and a leading edge in which the rotor blade is operably coupled to a hub of a turbine includes circulating heated air through an outflow channel from the blade root towards the blade tip, recirculating the heated air via a return channel from the blade tip to the blade root, whereupon the recirculated heated air becomes returned air, and reheating the returned air for further circulation.
