Abstract

Es ist eine Verdichterlaufschaufel (1) mit einem Schaufelblatt (2), einer sich an das Schaufelblatt (2) anschliessenden Plattform (3) und einem sich an die Plattform (3) anschliessenden Schaufelfuss (4) offenbart. Das Schaufelblatt (4) ist massiv ohne internes Kühlsystem ausgeführt und weist eine Vorder- und eine Hinterkante (5, 6), eine Saug- und eine Druckseite sowie eine Schaufelspitze (7) auf. Erfindungsgemäss zeichnet sich die Verdichterlaufschaufel (1) dadurch aus, dass das Schaufelblatt (2) der Verdichterlaufschaufel (1) an der Hinterkante (6) der Schaufelspitze (7) eine Aussparung (8) aufweist.

Figure imgaf001
A compressor blade (1) with an airfoil (2), a platform (3) adjoining the airfoil (2) and a blade root (4) adjoining the platform (3) are disclosed. The blade (4) is solid without internal cooling system and has a front and a rear edge (5, 6), a suction and a pressure side and a blade tip (7). According to the invention, the compressor blade (1) is characterized in that the blade (2) of the compressor blade (1) at the trailing edge (6) of the blade tip (7) has a recess (8).
