Title: WIND TURBINE BLADE DE-ICING SYSTEMS AND METHODS
Abstract:
There is a system and method for de-icing a wind turbine blade. The system includes a heater for heating air and for attaching to an interior surface of the wind turbine blade, a blower for moving air across the heater to generate a heated airflow, and a flexible duct for receiving the heated airflow and for releasing the heated airflow into the interior of the wind turbine blade. The method includes generating heated air in the interior of a wind turbine blade, moving the heated air into a porous duct within the interior of the wind turbine blade, and passing the heated air through the porous duct and into the interior of the wind turbine blade to heat a surface of the wind turbine blade.
