TLDR
In this article, a system and method for de-icing a wind turbine blade is described, which includes a heater for heating air and attaching to an interior surface of the wind turbine, 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 air into the interior of the turbine blade.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.read more

Controlling heating elements in a wind turbine system
TL;DR: In this paper, the authors present a method for controlling the temperature of a blade in a wind turbine system by setting a target temperature, inputting physical conditions of the blade and ambient conditions about the blade into a processor, and outputting a minimum amount of energy to a heating element of the turbine required to reach the target temperature.

TL;DR: In this paper, a pliable air duct system is created by selectively assembling pre-existing stock pieces in different combinations, where the stock pieces include disconnectable longitudinal joints and disconnectable circumferential joints, wherein the longitudinal joints enable interconnecting multiple stock pieces to achieve a desired tube diameter, and the circumference joints allow connecting multiple tube segments end to end to produce an air duct assembly of a desired length.

Method of de-icing a wind turbine blade
TL;DR: In this article, a method of de-icing a wind turbine blade comprises the steps of: generating heated air using heating means (10) provided in the root portion of the blade; and continuously circulating the heated air around the interior of the turbine through at least a portion of two more longitudinal blade cavities (24, 26, 28) defined within the blade.
