The PD-8 engine has more than nine thousand parts. This was reported by the General Designer of the United Engine Corporation (UEC).
According to him, the parts were specially given a special shape to dissipate heat.
Previously, Russia did not create such supersonic single-stage turbines. It has high loads on the stationary interaction of blade rings and the rotor. To ensure operation, very complex technical solutions had to be implemented
The PD-8 two-circuit turbofan engine was created at the UEC-Saturn enterprise. When developing the power plant, the experience of creating a more powerful PD-14 engine was used. To speed up PD-8 certification, computer modeling methods are used.
