A demonstrator of the latest PD-35 high-thrust aircraft engine was created with the widespread use of additive technologies. Alexey Mazalov, General Director of JSC "Center for Additive Technologies", revealed exactly which elements of the power plant were developed using the new technology.
According to him, the work required deep knowledge and experience to accurately comply with the optimal melting modes. This was necessary to guarantee the repeatability of the physical, mechanical and thermophysical properties of materials.
These are all kinds of body elements, brackets, nozzles, high-pressure compressor sectors, high-pressure turbine blades, low-pressure turbine working blades from the fifth to the eighth stage.
Mazalov added that more than 2,300 parts were created additively for the power plant.
General Designer of the United Engine Corporation (UEC, part of the Rostec State Corporation) Alexander Inozemtsev noted that PD-35 power plant tests are continuing on a test bench in Perm.
