A fifth generation plasma engine will be installed on the Su-57 fighter.

The Tsargrad TV channel reported that the chief designer of the Lyulka Design Bureau Yevgeny Marchukov, communicating with journalists, said that the Russian newest front-line fighter Su-57 will be equipped with a plasma engine.

This engine belongs to the fifth generation power plants. Its code name is "Product 30". When creating it, domestic and foreign experience was taken into account. According to the designer, the engine will be installed on the aircraft by 2020. This power plant has more power than its predecessors, and it is also cheaper. Its thrust is ten times its own weight.

Western critics, as Marchukov said, spoke with disapproval of the “Achilles heel” of the Su-57. She had a high radar visibility of the aircraft, since the thermal efficiency of its engine was too high. "The 30 product" will be assembled on a completely different principle. The unit will be equipped with a plasma ignition and thrust vector control system. Nozzles modernize. This will ensure the ignition of the plasma arc simultaneously with the supply of kerosene. This option will eliminate the "flare" - that is, the fiery column from the nozzle due to an excess of fuel in the combustion chamber will not escape. This will reduce the visibility of the aircraft in the infrared and radio wave ranges.

Another innovation of the “30 Products” is the variable degree of bypass. The power plant will be able to adapt in accordance with any flight conditions as instructed by the pilot. Machine control will become more simple. It should be noted that this ability will allow the Su-57 to have a cruising supersonic speed.
