Abstract[German]
Die vorliegende Erfindung betrifft eine Schaufel (1), insbesondere Leitschaufel oder Laufschaufel, für eine Strömungsmaschine (10), mit einer Vorderkante (1.1) und einer dieser entgegengesetzten Hinterkante (1.2), wobei die Schaufel (1) entlang der Vorderkante (1.1) ein Vorderkantenprofil mit wellenförmigen Profil abschnitten (PI, P2) aufweist, wobei das Vorderkantenprofil ausgehend von einem freien Ende (1.3) der Schaufel (1) in einem ersten wellenförmigen Profilabschnitt (PI) von einem Neutralpunkt (NP) der Vorderkante (1.1) in eine Erhebung (EH) und über einen weiteren Neutralpunkt (NP) in eine Vertiefung (VT) übergeht.[English]
The invention relates to a blade (1), in particular a guide blade or rotor blade, for a turbomachine (10), comprising a leading edge (1.1) and a trailing edge (1.2) opposite the leading edge. The blade (1) has a leading edge profile with wave-shaped profile portions (PI, P2) along the leading edge (1.1), and the leading edge profile transitions, starting from a free end (1.3) of the blade (1) in a first wave-shaped profile portion (PI), from a neutral point (NP) of the leading edge (1.1) into an elevation (EH) and, over an additional neutral point (NP), into a depression (VT).[French]
L'invention concerne une aube (1), notamment une aube directrice ou une aube mobile, conçue pour une turbomachine (10), comprenant un bord d'attaque (1.1) et un bord de fuite (1.2) opposé à celui-ci, cette aube (1) présentant le long du bord d'attaque (1.1) un profil de bord d'attaque avec des parties de profil ondulées (P1, P2), le profil du bord d'attaque partant d'une extrémité libre (1.3) de l'aube (1) dans un premier partie de profil ondulé (PI), d'un point neutre (NP) du bord d'attaque (1.1) vers une structure saillante (EH) puis, via un autre point neutre (NP), vers un creux (VT).
