Russia’s United Engine has carried out cruise-altitude simulation with the core of the Aviadvigatel PD-8 powerplant, intended for a revised version of the Sukhoi Superjet 100.
The test-bench simulation of operating conditions up to 12,000m (39,400ft) marks the initial stages of PD-8 certification testing.
Rostec says the core section includes the high-pressure compressor, combustion chamber and high-pressure turbine.
The Baranov Central Institute of Aviation Motors provided the facilities to conduct the tests, and Rostec states that these “confirmed the pre-calculated thermal model” of the compressor.
PD-8 engines will be offered on the ‘SSJ-New’, a version of the Superjet which will include a higher proportion of domestically-manufactured components and systems.
Rostec first deputy chief Vladimir Artyakov says the cruise-altitude tests will “facilitate evaluation of the power characteristics”.
He adds that the core will be subjected to a series of further certification tests running to March 2023, to run concurrently with testing of other prototype systems for the engine.
