United Engine Corporation (UEC), part of Russia's state-owned Rostec said it will begin testing gas generator components of the PD-35 ultra-high-thrust turbojet engine in autumn 2021.
The new components are characterized by their increased size, and unique equipment for processing large-sized parts is used in their production.PD-35 is an ultra-high-thrust bypass turbojet engine intended for installation on next-generation wide-body aircraft. It is one of the most ambitious projects in the Russian aircraft industry; an engine of this size and thrust will be built in Russia for the first time.
In addition to various UEC and UAC enterprises, almost all leading Russian research centers are involved in the work on the PD-35 project. The project will involve the use of several advanced technologies and materials. In 2020, UEC presented a composite fan blade of PD-35 and successfully tested a model of a fan blade on the PD-14 engine.
