The Eurasian Times has just published a graphic image of a single-engine fighter, believed to be of a future design, built by Russia based on the Su-57 fighter, in order to overcome the biggest weakness of this aircraft. , which is the lack of stealth. Accordingly, Sukhoi Corporation has embarked on the design of a new fighter, based on the original design of the Su-57, but enhancing stealth to a new level. Information from the Eurasian Times also said that it is likely that the next design of this new fighter jet will be equipped with only one engine. So far, the Russian Su-57 fighter has always been praised for its excellent maneuverability and speed, but to achieve speed and maneuverability, the Su-57 at the expense of invisibility. Although Russia has never acknowledged it, many military experts believe that the 3D vector engine design on the Su-57 is the fighter’s fatal weakness in front of enemy radars. Unlike the engine design hidden inside the stealth cover of the aircraft like the US F-22 Raptor, the engine of the Su-57 fighter is almost completely exposed. The radar-absorbing shell of the Su-57 fighter does not cover the aircraft’s engine parts, which means that, even though the entire Su-57 is invisible, its engine will still be targeted by enemy radars. side caught. The difficulty of Russia is that the engine of the Su-57 has too good performance, generates a lot of heat and is a 3D vector engine. All of these factors will make the Su-57’s engine impossible to fit inside the aircraft, nor can it be covered with a radar-absorbing shell on the outer surface. The US itself has admitted to trading the maneuverability, as well as the speed of the F-22 Raptor and F-35 fighters in exchange for superior stealth, but with the Su-57 everything is different. does not appear to be going in this direction. In addition, information about Russia’s next 5th generation fighter model will be equipped with an engine, also making many people curious and excited. Since the dissolution of the Soviet Union, Russia has not built any single-engine light fighter. Russia’s lightest fighter today, probably the MiG-29 – is also equipped with two engines, and can be considered a medium fighter. The single-engine fighter, in theory, is not much inferior to the twin-engine fighter in terms of weapon carrying capacity and aerial range. Not to mention, single-engine fighters will have lower production costs, shorter assembly times, and lower usage and depreciation costs. Currently, on the world market, the US F-16 single-engine fighter is still “hegemonic” and has almost no rival. Despite having only one engine, the US F-16 fighter is still capable of carrying up to 7.7 tons of weapons – only 300 kg less than the maximum weapon load of the Su-30. This is currently also the backbone of the US, with 1,300 in service, the most numerous fighter in the world at the moment. The test pilot pushed the Su-57 fighter to the limit of its maneuverability with a series of unbelievable flight maneuvers. Source: Sukoi.
