Sukhoi is working on a fifth-generation single-engine fighter

Specialists from the Sukhoi company are working on the creation of a fifth-generation single-engine fighter. It is reported by RIA News citing a source in the aircraft industry.

According to the information published by the agency, in the development of a light fighter will be used Technologymastered in the creation of the Su-57. In particular, we are talking about on-board electronics, radio-absorbing coatings, weapons and even the newest product 30 engine.

Also, the source told about some of the technical characteristics of the new combat aircraft. According to him, a single-engine fighter will weigh no more than 18 tons, develop a maximum speed of over Mach 2 and be distinguished by super-maneuverability and short take-off.

The ratio of the mass and thrust of the engine of the winged vehicle will be at least one. At the same time, the Al-31FN unit of series 3 and 4, previously tested on foreign aircraft, can be used as a power plant at the first stages of testing.

As for the single-engine layout, this is the first time such a solution is used for a fighter in Russia. However, in world practice, this is not a rare case. For example, F-16 and F-35 (USA), JAS-39 GRIPEN (Sweden) and J-10 (China) fighters have one power plant.

The advantage of this approach is the reduction in labor intensity of production and easier maintenance of the winged aircraft. At the same time, single-engine fighters have less "survivability" and a limited combat load.

    here to each his own. Russians have theirs - great Ukrainians have theirs
    Someone is developing a new one, someone is selling the last illiquid stock and then not their own (in order to make room for illiquid stock from the EU, USA and UK) wassat

    I don't think a single engine airplane is a good idea. On a twin-engine aircraft, if one engine fails, you can reach home on the second, and with one engine, the engine breaks down, these are the pitchforks, and in naval aviation the coffin is for the pilot. Our seas are mostly cold all the time, and you can't wait for rescuers in the icy water.

      The dual propulsion has an advantage in the aerobatic component, I mean maneuverability, from the complexity of production and maintenance to greater maneuverability. By the way, single-engine Americans are orders of magnitude more expensive to maintain and maintain, and when our two-engine engines were released, why did the author of the article not think about this? The article is a little profane, we need comparative tables with numbers, well, the survivability of 5 eFeshkas is a big question. The Americans themselves refuse them. In fact, after comparing ours against after theirs for with a minus sign, and ours against a big +. An American pilot and general of the military aviation, compared our, Soviet antediluvian Migi, calling them flying sledgehammers that cannot be killed with modern F-22s. The comparison is not in favor of eF22, because servicing one eF costs like 25 old moments, maintenance for frequent, this is a refueling, and mechanically, kicked, knocked, refueled, flew, that's it. Attached electronic including modern electronic warfare hang up, and these 25 will be more effective than 5x Americans.

    Most likely, the fighter, originally made with an eye to export, is a single-engine relatively inexpensive, but a modern fighter is in demand in some countries.

    News from six months ago, but in the photo it is still 2-motor ...

    Single-engine ones are an indicator of the advancement of the engine ...

    a single-engine light fighter is cheaper (many countries can afford it), smaller in size, and will have an unmanned mode in the near future. Upon reaching the perfect unmanned AI, the pilot will be completely removed from the light fighter, the machine will be fully automated, and its loss due to engine failure will not lead to the loss of the pilot, and the state will save a lot of money that is spent today on pilot training. In general, everything is going to reduce the size of fighter unmanned aircraft, today's light fighters such as f16, mig29 will be replaced by small supersonic uavs with AI, they will carry only 2 missiles, such uavs will be used in large numbers. If one aircraft with a pilot carries 6-8 missiles, and at least one anti-aircraft missile is required to destroy it, then in order to shoot down 4 uavs (each has 2 missiles = 8 in total), at least 4 missiles are needed, and they will fly at different altitudes

    If there is a demand for such aircraft, then why not. Both our technologies and our personnel, and if such aircraft are also sold, there are only advantages.

      Can it fit for Chinese and Indian aircraft carriers for plub aircraft?
