The invention concerns a system for deicing the leading edge of a nose inlet cowl for a turbine engine. The invention is characterized in that one of the two elements formed by the pressurized hot air supply duct (6) and by the protective casing (15) is longitudinally rigid, while the other of said elements comprises at least two mutually nested parts adapted to slide sealingly relative to each other; and said two elements (6, 15) are, on one side, rigidly fixed to one of said partitions (5) of the structure box (10), while, on the other side, said two elements are rigidly linked to each other (in 18) and are adapted to slide jointly relative to a sliding bearing (17) provided in the other partition (16).
Selon 1' invention , il y a prévu un système pour le dégivrage du bord d'attague d'un capote d' entree d'air pour turbomoteur comprenant: l'un des deux éléments constitues par la conduite (6) d' alimentation en air chaud sous pression et par l'enveloppe de protection (15) est longitudinalement rigide, tandis que l'autre desdits elements comporte au moins deux parties emboitées l'une dans l'autre et aptes a coulisser l'une par rapport à l'autre, de façon étanche ; et lesdits deux éléments (6, 15) sont, d'un coté, rigidement fixes à l'une desdites cloisons (5) du caisson (10) , tandis gue, de l'autre coté, lesdits deux éléments sont rigidement reliés l'un à l'autre (en 18) et sont aptes à coulisser en commun par rapport à un palier de coulissement (17) prévu dans l'autre cloison (16) .
