Russia’s United Engine has completed manufacturing work on the primary components of a prototype Aviadvigatel PD-8 powerplant.
The PD-8 is a lower-thrust variant of a family which centres on the PD-14 designed for the Irkut MC-21-310.
It is intended for eventual use on the Sukhoi Superjet 100 as a fully-domestic alternative to the PowerJet SaM146. The SaM146 is jointly produced by French and Russian firms, with Safran responsible for the high-profile core section.
Sections produced for the PD-8 include the high-pressure compressor, integrated discs, combustion chamber, and high-pressure turbine and the next stage will involve assembly.
