Parts of the newest domestic PD-8 aircraft engine for the Superjet SJ-100 and Be-200 are produced at UEC-Saturn using 3D printing methods with additive technologies. This approach reduces the weight of power plants while maintaining the strength of materials.
Deputy Chief Engineer of UEC-Saturn for Additive Technologies, Denis Fedoseev, noted that the company has introduced synthesized parts into the standard design of aircraft engines.
More than a dozen PD-8 parts are mass-produced using additive technologies. At the stage of experimental design work, more than 200 synthesized parts were designed, and more than a thousand were manufactured.
The United Engine Corporation (UEC) showed a video of the process of creating a part of the PD-8 aircraft engine using selective laser melting.
This refers to the oil sump housing, an important element of the unit's oil system. The manufacturing process includes mandatory optical control and X-ray control of the product, which confirm the quality of the part and its compliance with the specified parameters.
PD-8 engines are designed for the SJ-100 aircraft and the Be-200 amphibious aircraft. In the second case, tests will begin in mid- or late 2026.
Earlier, www1.ru reported that China will not take off without the PD-35: it has no other engine for the wide-body C-929.
