Sets of blades for gas turbine engines in Russia began to be produced using the "growing" technology from powder, which reduced the manufacturing time from 6 months to 10 days. This was announced by the president of the National Research Center "Kurchatov Institute" Mikhail Kovalchuk.
According to him, Russia is one of the five countries that possess a full cycle of creating gas turbine engines. One of the important parts is the engine blade, which rotates at tremendous speed at high temperature.
Now a set of blades for our aircraft is "grown" simultaneously by dozens instead of 6 months of manufacturing in 10 days. Before that, we made the part in such a way that we melted a large ingot, cut everything off from this ingot and made a small part. And today such a part is made of powder with a size of 30 microns.
The scientist added that "growing parts opens up prospects for the development of bionic engineering, which will allow designing things that cannot be made by classical methods, but can be "grown".
Earlier www1.ru reported that a sample of the PD-35 aircraft engine passed the first stage of testing.
