Abstract
Wind turbine blades with de-icing and/or anti-icing systems including at least one heating unit disposed along the blade's length and between the blade's chord, wherein each heating unit in turn comprises a plurality of heating elements connected both in series and in parallel in a matrix configuration by overlaps or cross-adjacent junctions between adjacent heating elements order to change the electric heating current flow disposing of any additional terminals cables and further enabling to generate a gradually increasing heat flux from the blade root towards the blade tip and from the trailing edge towards the leading edge through each individual heating unit adapting accurately to heat flux demand and hence reducing energy consumption for de-icing and/or anti-icing.
