Beschreibung
Zusammenfassung:	Disclosed is a cooled airfoil (61), the airfoil comprising a hub end (8) and a tip (9), an airfoil height (h) being defined between the hub end (8) and the tip (9). The airfoil (61) comprises a leading edge (LE), a trailing edge (TE), a suction side (SS) and a pressure side (PS). The airfoil (61) comprises a first airfoil height section (H1) adjacent the hub end (8) and extending towards the tip (9), wherein, in a meridional view, the leading edge (LE) and the trailing edge (TE) are straight along the first airfoil height section (H1), and the airfoil (61) comprises a second airfoil height section (H2) adjacent the tip (9) and extending towards the hub end (8), wherein, in a meridional view, the airfoil (61) is concavely shaped at the leading edge (LE) and is convexly shaped at the trailing edge (TE) along the second airfoil height section (H2). At least one cooling channel (65, 66, 67) is provided within the airfoil (61) and having a length principally extending along the airfoil height (h), wherein the cool
