The first fifth-generation Su-57 fighters equipped with the second-stage turbofan engine will be assembled in 2022," said Sergei Chemezov, Rostec's managing director. Russia is currently conducting flight tests of this engine, which should enable the Su-57 to achieve supercruise capability.
Targeted course 2022 for the series
"We are continuing to work on the second-stage engine [...] and I hope that by 2022, turbojet engines will be manufactured and mounted on aircraft, so that series production can begin in the next few years," said Chief Rostec, Sergei Chemezov. Russia is currently conducting flight tests of the second-stage engine on the Su-57, Chemezov said. "Several prototypes of the new jet engine have already been produced. Work is underway to finalize its assemblies and systems," he added.
Article 30, code name of the so-called second-stage turbojet engine, will be mass-produced at the UEC-Ufa Engine Production Association (part of the United Engine Corporation within Rostec). Ufa had previously manufactured the first prototype of the second-stage engine, which began flight tests in December 2017. It was reported earlier that series deliveries of fifth-generation Su-57 fighters equipped with the new engines would begin in 2023. The second-stage engine will enable the Su-57 fighter to develop supersonic speed without the need for afterburner.
