Renewal of Elements and Construction Units of Gas Turbine Engines by Means EBW

Renewal of gas turbine engines (GTE) is very urgent and at the same time highly complicated technical task. A cost effective alternative to new replacement parts is the restoration of the damaged or worn construction units and elements of GTE, including compressor and fan blades, as well as guide cases and hydraulic cylinders of nozzle block. The work contains the results of the development of reliable and efficient methods of gas turbine parts renewal by means electron beam welding. The technology of repair of three types of blade airfoil defects, replacement of damaged guide vanes and restoration of worn hydraulic cylinders was mastered. It is confirmed that electron beam welding is ideal for the solution of aircraft GTE construction units repair problems.
