MOSCOW, Dec 7-RIA Novosti. Work on creating a second-stage engine for the Russian fifth-generation su-57 fighter will be completed in 2022, Sergey Chemezov, General Director of the rostec state Corporation, told reporters.
"We continue to work on the engine of the second stage. Its flight tests as part of the aircraft are continuing. Several prototypes of the new engine were produced. Its nodes and systems are being refined. And I hope that sometime in 2022, the engines will be ready, "put on the wing", and within a few years we will launch their mass production, " he said.
Chemezov recalled that the Russian aerospace forces have already been handed over 10 vehicles for trial operation, a pilot batch, and by the end of the year the army should receive the first fifth-generation fighter under a previously signed contract for 76 vehicles, while the first production su-57S will be equipped with first-stage engines ("product-117").
The su-57 (formerly known as the PAK FA, experimental name T-50) is a fifth-generation Russian fighter designed to destroy all types of air, ground and surface targets. It first took to the air in 2010. The combination of high maneuverability with the ability to perform supersonic flight, as well as a modern set of avionics and low visibility provide the su-57 superiority over competitors.
The contract for the supply of 76 su-57 fighters to the Russian aerospace forces was signed at the Army-2019 forum. Currently, tests of this aircraft are continuing, during which the functioning of its systems is checked, as well as the operating modes of the second stage engine. The defense Ministry has repeatedly stated that the su-57 successfully passed tests in Syria.
The first production car, which was supposed to be delivered to the Ministry of defense at the end of December 2019, crashed near Khabarovsk during a test flight on December 24, the pilot managed to eject and survived. After the incident, the General Director of the United aircraft Corporation Yuri Slyusar told RIA Novosti in an interview that the results of the work of the Commission on the crash of the su-57 will be used to improve this aircraft.
To date, prototypes of the su-57 are flying with the "first stage" engine — the "product-117", which has already been put into mass production.
The engine of the "second stage" fuel efficiency and the specific thrust will significantly exceed the "product 117", and in constructive-technological performance and level of achievable options will fully comply with world standards, the engine of the fifth generation – to fly at supersonic speeds to besforsazhny mode.
