Abstract
Il est décrit une surface portante possédant une efficacité accrue pour une aube de rotor ou une aube de stator dune turbine à gaz ayant une rallonge de pointe prolongeant lune ou lautre des surfaces adjacentes à la pointe, cest-à-dire la surface du côté refoulement et la surface du côté aspiration, ou les deux. La rallonge de pointe définit une épaisseur à la pointe plus importante que la véritable épaisseur de la surface portante. La rallonge de pointe comprend une surface latérale de transition essentiellement définie le long dune courbe qui sétend tangentiellement à partir de la surface latérale correspondante. La rallonge de pointe définit une augmentation progressive dans lépaisseur sur une partie de la surface portante ayant une dimension radiale correspondant à au moins deux fois la véritable épaisseur.
