Rostec tests domestically-built engine control system for SSJ-NEW

Rostec’s United Engine Corporation has developed an automatic control system (ACS) for the new PD-8 aircraft engine, which will be installed on the SSJ-NEW passenger airliner.

The SSJ (Sukhoi Superjet) -NEW is a short-range narrow-body aircraft designed to replace the Sukhoi Superjet 100 that includes a greater proportion of domestically-built components. The PD-8 aircraft engine will serve as an alternative to the PowerJet SaM146 turbofan engine, produced by the PowerJet joint venture between Snecma (Safran) of France and NPO Saturn of Russia.

The system will control the engine’s operation, including thrust parameters and fuel consumption. It was developed from 100% domestically-made components and materials.

United Engine’s Perm-based facility UEC-Star has completed the development of the PD-8 ACS in just a year and a half – the shortest time possible. The mass production of this equipment is scheduled to start in 2023 when the qualification work is completed, and permits are obtained.

“The automatic control system for the PD-8 engine to equip the SSJ-NEW airliner used within the framework of the import substitution program will be assembled from completely domestic materials and electronic components. The system has a long service life and is resistant to failures. In January 2022, it will complete fine-tuning and bench testing, after which it will be handed over for bench tests as part of the engine,” said Vladimir Artyakov, First Deputy General Director of Rostec State Corporation.

Rostec presented the PD-8 as a generator, the ‘heart’ of the PD-8 engine, at MAKS air show in 2021. At the moment, two copies of the gas generator have been assembled and have successfully passed the tests. The tests confirmed the correct operation of the units, meeting the required temperature and pressure parameters and their compliance with the relevant environmental standards. Obtaining a type certificate for the PD-8 is scheduled for 2023.
