Abstract: Blade root receptacle for receiving a blade root of a rotor blade of a turbomachine. The blade root receptacle, for radially bearing in a form-fitting manner on the blade root, has a supporting flank which, in terms of a rotation axis, at least in proportions faces radially inward, wherein the supporting flank is provided with a convexity which, when viewed in an axially perpendicular section, at least in portions has a convex shape and, also when viewed in an axially parallel section, at least in portions has a convex shape.

Abstract: A method for producing a rotor disk or a rotor blade for a gas turbine compressor stage or turbine stage of an aeroengine, wherein at least one blade groove of the rotor disk for arrangement of a blade foot of a rotor blade for fastening the rotor blade to the rotor disk, or a blade foot of the rotor blade for arrangement in a blade groove of a rotor disk for fastening the rotor blade to the rotor disk is fabricated using an electrochemical material removal and in the axial direction has a profile which is curved once or more.

Abstract: An actively morphable vane includes a leading edge, a trailing edge downstream of the leading edge, a tip end, a hub end spaced radially outward from the tip end, a pressure side comprising a pressure surface, and a suction side comprising a suction surface. The pressure surface extends continuously between the tip end, the hub end, the leading edge, and the trailing edge. The suction side is positioned opposite of the pressure side and the suction surface extends continuously between the tip end, the hub end, the leading edge, and the trailing edge. The actively morphable stator vane also includes an actuator in mechanical communication with the tip end. The actuator is operable to selectively morph the actively morphable stator vane between a first configuration and a second configuration. The first configuration is optimized for a first operating condition, and the second configuration is optimized for a second operating condition.
