The United Engine Corporation (UEC, part of the Rostec State Corporation) uses rotational welding in the production of aircraft engines. This was reported by the company's press service.
UEC noted that the principle of the method is very simple: one part rotates very quickly, and the other is pressed tightly against it, and then physics comes into play.
Due to friction at the junction of parts, a high temperature arises, which melts the metal.
As a result, two parts are seemingly "rubbed" into each other, and a very strong connection is formed. Thanks to the technology, it is possible to reduce the welding time by 10 times. The seams are strong, and the amount of scrap is zero.
The corporation added that rotational welding allows to join materials that are "unweldable" by traditional methods, which is important for the production of modern aircraft engines.
It is worth recalling that UEC enterprises are currently producing PD-8 and PD-14 aircraft engines for promising passenger import-substituted liners MS-21 and SJ-100.
Earlier www1.ru reported that small aviation in Russia will receive a powerful impetus from Rostec and UAC.
