The head of the United Aircraft Corporation, Yuri Slyusar, at the Army-2023 forum, announced that the standard fighter engines (the so-called second-stage engines) need to be improved and continued testing. Although it was previously said that tests of turbojet bypass engines of the second stage for the Su-57 will be completed in 2022.
Arrived: the standard engine for the Su-57 needs to be improved
“ The engine of the second stage for the fifth-generation Su-57 aircraft is already in place, it flies, it is actually being tested, but they will not end the day after tomorrow. We do not deviate from the model agreed with the Ministry of Defense, talk that it does not exist is empty. But, like any fundamentally new engine, it needs refinement, it requires more testing , ”said Yuri Slyusar.
At the moment, AL-41F1 engines are being installed on the Su-57.
