Russian engineers, when developing the SJ-100 airliner, made certain design decisions to maintain maximum compatibility of the power structure of the SSJ-100 and SJ-100 airframe, including the pylon and engine mounting points. This was announced by Alexander Dolotovsky, Deputy General Director of PJSC Yakovlev, Director of the Superjet program.
According to him, the aircraft was actually unified in terms of the power plant at the engine mounting points.
That is, we remove SaM146 and install PD-8. This was done, among other things, in order to reduce the number of structural changes in the power structure of the airframe and reduce the amount of testing for strength and service life. Nevertheless, we still conduct such tests.
The top manager said that simultaneously with flight tests, the installation of the interior trim of the passenger cabin began on the fully import-substituted SJ-100. Experts aim to ensure that passengers do not feel any difference compared to the cabin of the classic SSJ-100.
The first flight with PD-8 engines took place in Komsomolsk-on-Amur last week. The plane was in the air for about 40 minutes, reached a height of up to 3,000 m and a speed of 500 km/h.
