  • Patent number: 9003655
    Abstract: 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.

  • Publication number: 20100169048
    Abstract: A maintenance planning method for turbomachines, especially for gas turbine aircraft engines, is disclosed. In an embodiment, the method includes: a) data obtained from the previous maintenance of turbomachines is stored in a database in a structured manner, where the data especially correlates maintenance work carried out with operating loads of a serviced turbomachine; b) in order to pre-plan the maintenance of a turbomachine undergoing further maintenance, the maintenance work to be carried out is planned in terms of type and sequence on the basis of the database; and c) the turbomachine undergoing further maintenance is inspected for the final planning of the maintenance, and the type and/or sequence of the maintenance work to be carried out, which was specified during the pre-planning of the maintenance, is adapted and/or supplemented on the basis of the inspection.
