The present invention describes a method and an apparatus (12) for surface strengthening and/or smoothing of an integrally bladed rotor area (9) of a jet engine. The rotor area (9) can be connected to a device (13) and held by the latter inside the container (14) in a position equivalent to an at least approximately horizontal orientation of a rotary axis (15) of the rotor area (9). A space delimited by the container (14) and the rotor area (9) between a surface (17) of the rotor area (9) and that surface (18) of the container (14) facing the rotor area (9) is filled at least partially with strengthening and/or smoothing elements (19). A relative movement is generated between the surface (17) of the rotor area (9) and the strengthening and/or smoothing elements (19). The surface region (17) of the rotor area (9) to be strengthened and/or smoothed is at a distance from the surface (18) of the container (14) facing the rotor area (9).
Method for surface strengthening and/or smoothing of an integrally bladed rotor area of a jet engine, with the rotor area being arranged inside a container, and a space delimited by the container and the rotor area between a surface of the rotor area and that surface of the container facing the rotor area being filled at least partially with strengthening and/or smoothing elements, and a relative movement being generated between the surface of the rotor area and the strengthening and/or smoothing elements, characterized in that a rotary axis of the rotor area is arranged at least approximately horizontally inside the container during surface strengthening and/or smoothing of the rotor area, and the surface region of the rotor area to be strengthened and/or smoothed is at a distance from the surface of the container facing the rotor area.
Apparatus for surface strengthening and/or smoothing of an integrally bladed rotor area of a jet engine with a device for holding the rotor area inside a container to which the rotor area can be connected, characterized in that the rotor area can be held by the device in a position inside the container equivalent to an at least approximately horizontal orientation of a rotary axis of the rotor area.
