Russian rocket engines are actively transitioning to 3D printing technologies. This approach allows for faster manufacturing of complex components, reduces the number of technological operations, and makes production more flexible. About 40% of the RD-191 engine parts are already produced using additive technologies. Details were disclosed by Roscosmos.
The RD-191 is one of the most advanced Russian liquid-propellant rocket engines. It was developed by NPO Energomash specifically for the Angara family of launch vehicles. This engine is used on the Angara-1.2 and Angara-A5 rockets.
In addition to implementing 3D printing, the Russian space industry continues to develop its own production base. Roscosmos reported that over the past five years, industry enterprises have completely replaced imports for approximately 30 types of materials used in the creation of space technology.
Russia has also developed the first domestic all-weather radar with a phased array antenna for Earth remote sensing satellites. Such equipment allows obtaining images of the planet's surface regardless of cloud cover and time of day.
Modernization continues in manned cosmonautics as well. Onboard electronics of Russian spacecraft are equipped with new-generation microelectronic modules created using 3D memory chip assembly technology.
