Abstract

The invention regards a de-icing / anti-icing system comprising at least two conductive structures (3', 3'') embedded in an article (2), which includes an outer surface (5) being designed as an aerodynamic surface, at least one of the conductive structures (3', 3'') is arranged adjacent the outer surface (5), a control unit (39) is adapted to control the energy supply to the conductive structures (3\ 3'') for generating heat to the outer surface (5) One conductive structure (3') comprises a first conductive nano structure (19'), the conductive structure's (3') conductive property differs from the conductive property of the other conductive structure (3'') comprising a second conductive nano structure (19'').

Description

technical field [0001] The invention relates to a multifunctional de-icing / anti-icing system according to the preamble of claim 1 and to an object comprising an outer surface acting as an aerodynamic surface when the object moves relative to the air. Background technique [0002] Objects moving through the air, such as wind turbine blades, can freeze under certain weather conditions. Today's wind turbine blade aerodynamic surfaces are protected from icing by anti-icing and de-icing devices placed at or below the aerodynamic surface. Icing is known as an undesirable phenomenon in which the gradual formation of ice occurs on aerodynamic surfaces. [0003] Thus, composite or metal structures of objects comprising aerodynamic surfaces are formed to have an aerodynamic function and are subjected to ice formation on their outer surfaces under certain operating conditions. Ice formation has a strong negative effect on the aerodynamic efficiency of the affected object. To compens...
