Abstract: A method for modifying the mechanical and surface properties of a component. The method involves: removably attaching a component to at least one component support that is located within a vibratory trough of a component treatment apparatus, the at least one component support being a support shaft upon which the component is removably mountable within the vibratory trough; supplying the vibratory trough with treatment media; moving the component support or the vibratory trough so that the component is immersed into the treatment media; vibrating the vibratory trough to provide a substantially uniform surface treatment of the component, the vibratory trough being movable by at least one trough vibrating mechanism whose actuation is controlled by a controller in response to signals received from at least one sensor located on or within the vibratory trough; removing the component from the treatment media; and detaching the component from the component support.

Abstract: The present invention describes a rolling tool device for compression rolling of, in particular, blade elements of a rotor area of a jet engine provided with a tool carrier. The tool carrier is connectable to a carrier spindle. Furthermore, two pliers-type bodies are rotatably connected to the tool carrier. The pliers-type bodies are each provided with a rolling area, with a distance between the rolling areas being variable in dependence of the rotary movement of the pliers-type bodies. In accordance with the present invention, an axis of the carrier spindle in the state connected to the tool carrier passes between the rolling areas through a contact point present at a distance between the rolling areas equal to zero.

Abstract: A method for determining a flow behavior of a medium uses at least one analysis device placed inside the medium. The at least one analysis device is freely moveable in the medium and supplies data characterizing at least one property of the medium flow behavior to a data evaluation device. The at least one property of the medium flow behavior is determined by the data evaluation device on the basis of the data in selected areas or in all areas through which the at least one analysis device flows with the medium.

Abstract: The present invention describes a method and an apparatus for surface strengthening and/or smoothing of an integrally bladed rotor area of a jet engine. The rotor area can be connected to a device and held by the latter inside the container in a position equivalent to an at least approximately horizontal orientation of a rotary axis of the rotor area. 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 is filled at least partially with strengthening and/or smoothing elements. A relative movement is generated between the surface of the rotor area and the strengthening and/or smoothing elements. 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.

Abstract: For surface strengthening of blisk blades, a blade area of the blisk is completely inserted into a water bath (13), and a multitude of high-pressure water jets are injected into the water bath which are directed bilaterally and essentially vertically—and opposite to each other—to both blade sides. Cavitation bubbles imploding near the blade surface that are generated in the water bath on the periphery of the high-pressure water jets to produce micro jets upon imploding, exerting an effect on the blade surface, creating plastically formed depressions without sharp edges. An apparatus for performing the method includes a container (3), a jetting unit (6) having parallel spaced apart water-jet tubes (4) with nozzle openings connected to a high-pressure water conduit (5) to produce the high-pressure water jets.

Abstract: The present invention describes a method for the production of a one-piece rotor area, preferably of a jet engine. The rotor area includes an annular base body and several, circumferentially distributed blade elements extending essentially radially from the base body. Residual stresses are imparted to the blade elements in surface-near areas by way of roller compression using a rolling tool introduced between the blade elements. During roller compression, one each area of a blade element is arranged between areas of the rolling tool, with longitudinal sides of the blade element being simultaneously roller-compressed. According to the present invention, the rolling tool is radially introduced between the blade elements and the surfaces of the blade elements are roller-compressed, thus at least the blade elements having a roller-compressed surface.

Abstract: 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).

Abstract: In a method for determining the surface coverage obtained by shot peening to ensure uniform and complete strengthening of the surface of components, in particular blisk blades, a shot-peened surface topography is digitalized by an optical digital recording unit. A three-dimensional height profile is then prepared by measuring and evaluation software which includes both indentations and excrescences due to shot peening and also roughnesses due to manufacturing, which are smaller than the excrescences and indentations. The roughnesses are subsequently filtered out from the height image by a software filter using mathematical methods. A height diagram with the indentations situated below a zero line is established, with the size of these indentations being calculated in relation to the total area in the height diagram and the extent of coverage of the entire shot-peened surface being determined therefrom.

Abstract: With a method for surface strengthening and smoothening of metallic components, in particular of rotors or rotor drums (7) with integral blading for aircraft engines, the components are loaded in a vessel (2) which is filled with strengthening elements (10). A tumbling movement is performed by which the metallic components are strengthened and smoothened by a relative movement between the workpiece surface and the strengthening elements in one process step. The strengthening elements (10) have a circumferential, rounded edge area, or compressive strengthening area (13) for strengthening the surface, and, extending therefrom on both sides, a flatly curved smoothening area (14) for smoothening the surface roughened by strengthening. With low time and apparatus investment, workpieces can be provided that feature high fatigue strength and advantageous aerodynamic properties.
