Abstract: A compressor component having an improved airfoil profile so as to eliminate previously known vibratory issues in the blade tip is disclosed. By altering the airfoil profile throughout its span, the natural frequency of the airfoil is altered so as to not coincide with a critical engine order of the compressor. Further, the present invention provides a novel airfoil profile in accordance with the coordinates of Table 1.

Abstract: The invention relates to a steam turbine, in particular a high-pressure turbine, which is enclosed by an inner casing, split into a top part and a bottom part, and an outer casing. The steam turbine, for the purpose of bleeding, has a bleed slot, which leads form the blade duct of the steam turbine through the inner casing. According to the invention, the inner casing has a shrink ring, which on the one hand holds together the bottom part and the top part of the inner casing and on the other hand forms an annular space above the bleed slot for the purpose of collecting bleed steam and passing it into a pipe connection. The shrink ring has a cavity in its center and flat sides being adapted to the outer surface of the inner casing. The cavity of the shrink ring, together with the outer surface of the inner casing, forms the enclosed, tight annular space. the shrink ring is distinguished by the few components and a short production and assembly time.
