Abstract

L’invention concerne une pale (10) d’hélice de turbomachine en matériau composite comportant un intrados (14) et un extrados (16) jointifs en un bord d’attaque (18), ledit bord d’attaque (18) étant recouvert d’un clinquant métallique (20) qui est collé sur ledit bord d’attaque (18) au moyen d’un joint de colle (24), ladite pale (10) comportant en outre au moins une surface recouverte d’un élément (28) chauffant électriquement et/ou thermiquement conducteur qui est apte à provoquer une fonte de givre ou de glace recouvrant ladite pale (10), caractérisée en ce que l’élément chauffant (28) conducteur est emprisonné dans le joint de colle (24) entre le bord d’attaque (18) et le clinquant (20). Figure pour l'abrégé : Figure 6.
