| 摘要 |
The present invention relates to a blade (1) for a gas turbine, having a leading edge and a trailing edge, which are connected by a pressure side and an intake side, wherein, in at least one segment of a stacking axis, the blade has a cross section with a profile with a common profile tangent (P) at a leading edge region and a trailing edge region, a leading edge tangent (V) at the leading edge, which is perpendicular to the common profile tangent, a trailing edge tangent (H) at the trailing edge, which is perpendicular to the common profile tangent, and a camber line (S), which extends, at an equal distance from the pressure side and the intake side, from a center point (MV) of a leading edge circle (KV), up to a center point (MH) of a trailing edge circle. |

1. A blade (1) for a gas turbine,
having a leading edge and a trailing edge, which are connected by a pressure side and an intake side, wherein, in at least one segment of a stacking axis, the blade has a cross section with a profile with a common profile tangent (P) at a leading edge region and at a trailing edge region, a leading edge tangent (V) at the leading edge, which is perpendicular to the common profile tangent, a trailing edge tangent (H) at the trailing edge, which is perpendicular to the common profile tangent, and a camber line (S), which extends, at an equal distance from the pressure side and the intake side, from a center point (MV) of a leading edge circle (KV), up to a center point (MH) of a trailing edge circle, wherein the blade thickness (t) between the pressure side and the intake side increases, extending from a trailing edge thickness (tH) at the center point of the trailing edge circle in a camber line segment (a), the length of which is at least 15%, in particular at least 19%, and at most 25%, preferably at most 21%, of a length (s) of the camber line between the center point of the leading edge circle and the center point of the trailing edge circle, toward the center point of the leading edge circle, increasing to at least two times, in particular to at least 2.5 times, the trailing edge thickness. |
