Specialists from the United Engine Corporation (AO "ODK") have begun using a rotary friction welding machine in aircraft engine production. This was stated by leading engineer of the Research Institute of Technology and Organization of Engine Production (NIID), Almaz Miniakhmetov.
This is the first equipment in Russia for joining superalloy parts with a diameter of up to 400 mm. It was manufactured according to the technical specifications of NIID.
According to Miniakhmetov, friction welding is used in manufacturing the high-pressure compressor rotor of the promising PD-35 engine.
In the machine, under strong compressive force and rotation, the parts are joined to each other without gaps and without metal destruction.
The finished structures are lighter, while the joining of parts in them is strong and reliable.
About the PD-35
The PD-35 is the base engine of a family of turbofan jet engines intended for wide-body aircraft. Its characteristics are being verified on an open test stand.
The PD-35 has already passed the first stage of testing. During 50 runs, the engine produced thrust of more than 35 tonnes.
At the second stage, ODK specialists are evaluating the operation of the high-pressure compressor blades and the high-pressure turbine developed from new Russian materials.
