The United Engine Corporation (UEC, part of Rostec) presented the technologies of the future in the industry at Innoprom in Yekaterinburg. The use of thermoplastic materials is one of the key areas of engine building development, the corporation noted.
The materials reduce the weight of the aircraft engine, reduce its cost and shorten the manufacturing time of parts.
Vitaly Krupennikov, Deputy Chief Engineer of the pilot plant for polymer composite materials "UEC-Saturn", noted that in comparison with traditional composites, thermoplastics are characterized by a reduction in the production cycle, the possibility of repair and recycling of parts.
Their use is a global trend in aircraft construction. We expect that by 2030 at least 5% of the mass of the aircraft engine will be made up of parts made of thermoplastic polymers, and by 2040 this figure will reach 25%.
The enterprises "UEC-Saturn" and "UEC-Aviadvigatel" are already developing technologies for pressing and welding thermoplastic materials. They are planned to be introduced in the production of new generation aircraft engines PD-14, PD-8 and PD-35.
Thermoplastics are planned to be used for the manufacture of elements of the outer contour of aircraft engines, including fan blades and housing, gas generator skin and dividing housing.
