The United Engine Corporation of Rostec has completed the assembly of the first experimental gas generator of the new promising PD-8 engine for regional aircraft, in particular, the SSJ-NEW. The next stage of the work will be bench testing and confirmation of the main parameters. A full-scale sample of the gas generator will be presented at the MAKS-2021 exhibition.
During the development work on PD-8, assembly equipment was designed and manufactured, sensors were installed to monitor the condition of the product during testing, and the gas generator rotor was assembled and balanced.

"Rostec continues to create a line of domestic engines for Russian passenger aircraft of different classes. The work on the PD-8 for the short-haul SSJ-NEW largely takes into account the experience of creating its "older brother" — the PD-14 engine for the medium-haul MS-21 airliner. At the moment, we have completed the assembly of the first experimental gas generator — the "heart" of the power plant, and are preparing to start testing it. In the near future, we will have a crucial moment — the first launch, " said Vladimir Artyakov, First Deputy General Director of Rostec State Corporation.

At the first stage of testing, the automatic control system will be debugged, the launch will be worked out, and the main characteristics of the nodes will be determined. The tests will allow us to experimentally confirm the correctness of the design solutions laid down.
The project of creating a PD-8 main propulsion system for SSJ-NEW aircraft is implemented by a wide cooperation of enterprises of the UEC holding of the Rostec State Corporation. The premiere of the gas generator is planned at the MAKS-2021 air show, which will be held on July 20-25 in Zhukovsky, near Moscow.
As previously reported, in the summer of 2020, UEC created the first samples of composite blades for the PD-35 ultra-high-thrust turbojet engine, which is planned to be installed on promising long-haul aircraft, and began their bench tests.
