Abstract
The heating device comprises electrically conducting longitudinal fibers extending substantially parallel to a leading edge of the aerofoil close to said leading edge, and means for electrically connecting the ends of the longitudinal conducting fibers to an electric power supply. The conducting fibers are grouped together in conducting rovings forming part of a hybrid fabric which furthermore includes a weft of electrically insulating fibers woven together and woven with the conducting rovings.
Claims5
A device for heating an aerofoil, comprising electrically conducting longitudinal fibers extending substantially parallel to a leading edge of the aerofoil in a region of the aerofoil including said leading edge, and means for electrically connecting the ends of the longitudinal conducting fibers to an electric power supply, wherein the conducting fibers are grouped together in conducting rovings forming part of a hybrid fabric embedded in a set resin, said hybrid fabric further including a weft of electrically insulating fibers woven together and woven with the conducting rovings, and wherein the electrical connection means comprise, at each end of the hybrid fabric, a metallic conducting cable arranged along said end of the hybrid fabric and projecting from at least one lateral edge of the hybrid fabric, and a metallic mesh folded along said end of the hybrid fabric in such a way as to envelope said conducting cable and the hybrid fabric near said end.
