Additive technologies have long been used in the development and assembly of aircraft engines in Russia. But they were used little in previous generation installations, said Alexey Mazalov, General Director of JSC "Center for Additive Technologies".
He recalled that if only one item made by additive manufacturing is used in the PD-14 aircraft engine for the MS-21, then the PD-35 high-thrust demonstrator engine has 65 items and more than 2,300 parts.
The introduction of 3D printing technologies reduces the manufacturing time of parts and promotes the introduction of new design solutions. These advantages made it possible to create the PD-35 demonstrator engine on time.
The United Engine Corporation (UEC, part of the Rostec State Corporation) continues to work on the PD-35 technology demonstrator engine, noted Alexander Inozemtsev, General Designer of UEC. He recalled that there have never been installations of such power in the history of Russia.
