| 摘要 |
The invention relates to a blade of a row of rotor blades or stator blades for use in a turbomachine, wherein the blade is formed with a substantially convex suction side (SS) and a substantially concave pressure side (DS), and with a leading edge (VK), against which the flow flows, and a trailing edge (HK), away from which the flow flows. The blade has at least one recess in the contour, which is provided on at least one of the sides of the blade comprising the suction side (SS) and the pressure side (DS), wherein the recess in the contour comprises a step-down edge (AK), a contour corner (KE) and a flank face (FF) provided between the step-down edge (AK) and the contour corner (KE), and wherein the recess in the contour extends over at least part of the depth of the profile and/or the height of the profile of the blade. |
