Abstract: A compressor assembly, and more in general relates to a compressor for a gas turbine providing a solution that teaches to locate within a cavity formed by the outer casing of the compressor and the inner vane carrier a separator element, or membrane, such to divide the cavity into two sub-cavities. This advantageously results in a more flexible design with respect to the positioning of the flange blow-off extractor and to the cavity sizing, as the flange position is not necessarily the boundary for the flow anymore as it would be without the separator element.

Abstract: A gas turbine includes a rotor concentrically surrounded by a casing, with an annular hot gas channel axially extending between the rotor and the casing. The rotor is equipped with a plurality of blades, which are arranged on the rotor in an annular fashion. Each of the blades is mounted with a root in a respective axial slot on a rim of the rotor radially extending with an airfoil into said hot gas channel and adjoining with an axially oriented root surface to an annular rim cavity. Cooling means are provided at the root of each of said blades to receive cooling air being injected into said rim cavity through stationary injecting means. An optimized cooling is achieved by providing the root surface to be an essentially plane surface and the cooling means including a scoop for capturing and redirecting at least part of the injected cooling air, which scoop is designed as a recess with respect to the root surface.
