Titanium Alloy Blades For Aircraft Engines Have A New Production Technology

It is reported that Rostech United Engines has introduced a unique technology for the production of aircraft engine blades.  Innovative developments have made it possible to produce the most precisely shaped parts, including large ones, while lowering labor costs and removing human labor from the production process. 

The UEC Saturn plant in Libinsk produces engine blades, using a device for twisting high-precision titanium blades and a technology for mixing and stamping two-phase titanium blades. 

The blade of a gas turbine engine is one of the most complex and scientifically intensive engine parts in terms of design and production.  The product is required to have the most accurate shape, to withstand high loads and high temperatures, and is produced using rare metals and unique alloys as well as composite materials to ensure low weight and high strength of the workpiece.  Only six  countries in the world have the capacity to design and produce engine blades.  The possession of such skills shows that the country's mechanical engineering industry is highly developed. 

"Both of these inventions relate to the production of blade stamping parts.  The torsion unit is built into the process flow and now produces blades for advanced aircraft engines using only Russian-made equipment, expanding the range and capacity to produce large blades.  Hybrid stamping, in turn, is based on additive manufacturing and isothermal stamping techniques that meet the required standards in terms of production economy and mechanical specifications.  "Igor Ilyin, chief engineer at PJSC UEC Saturn. 

These inventions were exhibited at the Archimedes 2022 International Salon, where they won gold and silver awards. 

Rostech United Engines manufactures and produces the PD-8 series of civil aircraft engines extensively using the latest technology to replace imported SJ-New, PD-14 to replace medium-range MS-21, and PD-35 to replace advanced wide-body long-haul aircraft.
