At the International Engine Building Forum, the United Engine Corporation (UEC), part of Rostec State Corporation, presented its advanced developments for the Russian aviation industry. One of the key innovations was the blades for the PD-35 technology demonstrator engine, made using modern technologies and materials.
For the first time, UEC demonstrated working and nozzle blades for a low-pressure turbine, which were manufactured using additive technologies. 3D printing technology ensures high precision in the manufacture of parts, which is critical for the efficient operation of engines. In addition, the stand featured fan blades made of polymer composite materials, which reduces the weight of components by up to 30%.
The use of additive technologies and composite materials is considered one of the priorities in the development of new aircraft engines. These technologies are necessary to create lighter, more efficient, and high-performance engines, which in turn will positively affect the overall competitiveness of the Russian aviation industry.
Earlier, www1.ru reported that a sample of the PD-35 aircraft engine passed the first stage of testing.
