A method for maintenance, in particular repair, of gas turbines, in particular aeroengines. Gas turbines are disassembled, with modules and/or assemblies and/or individual parts of the gas turbines then being inspected and/or repaired, and then assembled from inspected and/or repaired and/or new modules and/or assemblies and/or individual parts. The maintenance is subdivided into at least two repair steps, wherein modules and/or assemblies and/or individual parts to be repaired are moved through repair stations in order to move the modules and/or assemblies and/or individual parts of the or each gas turbine to repair stations adapted for this purpose in order to carry out the repair steps. The repair stations may be arranged in repair lines, with gas turbine modules, assemblies and/or individual parts being directed to different repair lines after inspection. The method permits gas turbine maintenance to be performed in a conveyer belt manner.

1. A method for maintenance of gas turbines, wherein the gas turbines are disassembled into modules and/or assemblies and/or individual parts, the modules and/or assemblies and/or individual parts of the gas turbines are inspected to determine which modules and/or assemblies and/or individual parts
1. A method for maintenance of gas turbines, wherein the gas turbines are disassembled into modules and/or assemblies and/or individual parts, the modules and/or assemblies and/or individual parts of the gas turbines are inspected to determine which modules and/or assemblies and/or individual parts require repair, and repairing the modules and/or assemblies and/or individual parts to be repaired, wherein the repair is subdivided into at least two repair steps, wherein modules and/or assemblies and/or individual parts to be repaired of at least one gas turbine are moved through repair stations adapted for the purpose of carrying out specific repair steps, wherein the modules and/or assemblies and/or individual parts are repaired in different repair lines containing repair stations, with a decision on the repair line to which a module and/or assembly and/or individual part to be repaired will be sent being made after inspection of the modules and/or assemblies and/or individual parts, wherein modules and/or assemblies and/or individual parts of gas turbines are moved discontinuously on a cycle through the selected repair stations or the repair lines, and wherein two or more repair steps are carried out in succession on the same modules and/or assemblies and/or individual parts within one repair line, wherein the modules and/or assemblies and/or individual parts are moved to at least one matched repair station in order to carry out the repair steps, wherein each matched repair station includes two or more identical repair stations provided for at least some of the repair steps, such that the same repair steps can be carried out at the same time on different modules and/or assemblies and/or individual parts within one repair line. 2. The method as claimed in claim 1, wherein the repair lines include at least one of a coating-intensive repair line and a welding-intensive repair line and a non-welding-intensive repair line. 3. The method as claimed in claim 1, wherein in addition to the repair stations in the repair lines, central repair stations are provided, wherein modules and/or assemblies and/or individual parts from different repair lines are passed to the central repair stations. 4. The method as claimed in claim 3, wherein the central repair stations include at least one of a heat treatment station, a washing station and an electroplating station. 5. The method as claimed in claim 1, wherein the modules and/or assemblies and/or individual parts are inspected after repair. 6. The method as claimed in claim 1, wherein before being disassembled, the gas turbines are precleaned as a unit, and in that the modules and/or assemblies and/or individual parts are cleaned again before repair. 7. The method as claimed in claim 1, wherein gas turbines are assembled from inspected and/or repaired and/or new modules and/or assemblies and/or individual parts after repair.
