Abstract: front page image
(EN)An aircraft transparency has a heatable member to remove fog, ice and snow from the outer surface of the transparency. The heatable member includes a pair of spaced parallel bus bars with the ends of the bus bars offset from one another, and a coating including a plurality of spaced segments of an electrically conductive coating electrically connecting the bus bars. The ratio of the major diagonal to the minor diagonal is in the range of greater than 1 to 1.25 to more uniformly heat the coating and the outer surface of the transparency.
(FR)La présente invention concerne un vitrage d'avion comportant un élément chauffant pour ôter la buée, la glace, et la neige, de la surface externe du vitrage. L'élément chauffant comprend une paire de barres omnibus parallèles espacées, les extrémités des barres omnibus étant décalées les unes par rapport aux autres, ainsi qu'un revêtement comprenant une pluralité de segments espacés d'un revêtement électroconducteur connectant électriquement les barres omnibus. Le rapport entre la grande diagonale et la petite diagonale se situe dans un domaine compris entre plus de 1 et 1,25 afin de chauffer de manière plus uniforme le revêtement et la surface externe du vitrage.
