At the National Research Center "Kurchatov Institute", a technology for printing a combustion chamber swirler has been developed for the PD-14 engine. The material utilization rate reaches 98%, according to the Russia 1 TV channel.
Yulia Dyakova, Director of the National Research Center "Kurchatov Institute", explained that when swirlers are made using standard methods and holes are cut on a machine, there is a high risk of defects.
There are dozens of such swirlers in the engine. When you make them with additive technologies, you get everything the same.
Dyakova explained the advantage of additive technologies using the example of blanks that are very difficult to create using conventional mechanical processing methods.
For example, how do you make a bone? It's hollow inside. How do you make a completely closed structure? It's impossible. But with additive technologies, it really can be done.
Today, the National Research Center "Kurchatov Institute" has the only full cycle of additive production in Russia — from the development of specialized alloys and powder compositions to the creation of technologies for manufacturing parts and preparing a complete set of regulatory documentation.
Dmitry Bloshchinsky, Deputy General Director of the United Aircraft Corporation, noted that the industry has bet on additive technologies. According to him, 3D printing of metal parts can revolutionize the entire approach to aircraft production in the country.
