Abstract

Aube présentant un meilleur rendement de transmission de chaleur. Elle comprend un pied, une plate-forme et une pale dans laquelle sont formées des passages de refroidissement 19 qui s'étendent au-dessous de la surface de l'intrados et de l'extrados de la pale dans le sens de l'envergure de la pale, chacun des passages 19 comportant une série de protubérances circulaires 36 qui s'étendent sur au moins 120 degrés et de préférence sur environ 360 degrés de la circonférence du passage dans des plans perpendiculaires à la paroi du passage et sont espacées les unes des autres d'une distance comprise entre 2 et 6 diamètres de passage. Application aux turbines à gaz.
