As part of the creation of a specialization center for the restoration of parts and assemblies at ODK-Service, 11 new technological processes for repairing aviation and ground gas turbine engines will be implemented. The project is being carried out with the participation of ODK and Rostec State Corporation, which are expanding their competencies in the field of power plant restoration and maintenance.
New technologies include modern methods of processing and restoring parts, controlling the geometry and structure of materials, as well as high-precision welding and spraying methods. Some of the solutions are already undergoing the development stage, and the launch of the center is planned by the end of the year.
According to the company, over the past 15 years, repair technologies for 260 parts of various engine types have already been introduced in the industry.
Among the areas planned for use are electron beam welding, laser powder cladding, electrical discharge machining, high-precision measurements of blade geometry on coordinate measuring machines, and metallographic analysis. The development of detonation, high-velocity, and plasma spraying technologies in vacuum, as well as new methods for repairing casing and pipeline elements, is also envisioned.
Essentially, this involves expanding the production base for aircraft engine repair with a transition to more precise and technologically complex methods of parts restoration instead of replacement.
