Disclosed is a borescope-based inspection method for inspecting a condition of an externally invisible component of a device, in which method a change in the microstructure of the component material is determined based on a physical property and evaluated in relation to at least one reference physical value that accounts for aging of the component. Also disclosed is a system having a computing unit and at least one probe for performing such an inspection method for selecting, with the aid of or, in particular, by a computer, a non-destructive testing method for measuring the physical property and for actually measuring the physical property, for performing a comparison between a measured value and the reference value and for performing an evaluation of a tolerance between the measured value and the reference value.

Inspection method for inspecting a condition of an externally invisible component of a device using a borescope

A guide system for repairing turbomachinery includes a housing; a guide tube have a hollow interior for accepting a working tool module; an axial motor for moving the guide tube axially with respect to the housing; a rotational motor for rotating the guide tube with respect to the housing; and an attachment for securing the housing with respect to a turbomachinery casing. A repair kit and method are also provided.

Repair tool for turbomachinery and related method

The invention relates to a method for cleaning a turbo-machine stage () consisting of at least one of the following steps: a cleaning nozzle () is introduced into an opening of a turbo-machine, in particular into an inspection opening (); and the blade () of the stage is acted upon by solid particles, said particles subliming at the blade temperature, in particular into dry ice particles.

Cleaning of a turbo-machine stage

A blade of a turbomachine, in particular of a gas turbine, is disclosed. The blade includes at least one fastening section for fastening the same in a locating section of a rotor-side or stator-side component of the turbomachine. The, or each, fastening section has a core region which is made of a relatively brittle and relatively light material and is embedded in an encasing region made of a material having relatively high ductility.
