The moral of the story is, don't drive a Ferrari if the only way to pay for it, is through a loan which you would then pass on to your children for them to worry about and at the risk of further downgrading their credit rating.

The deflections of the rudders are calculated taking account of the forces that the parts and the whole can sustain. You don't want rudders so strong that deflecting them could destroy your aircraft. This is one of the advantages of fly-by-wire, or fly-by-light as the case may be.
Sounds great. But you have to design you engine to be able to tap enough air from the high pressure compressor to inject into the tail pipe. No doubt every designer of military aircraft engines is looking at it, but I think, not being competent to judge these matters, that it will not be easy.
that flanker 2D nozzle is the crudest TV nozzle i've ever seen, not even a nozzle i think, just a cowling over the engine nozzle, otherwise there will be pressure loss in such nozzle
having said that, i think T-50 still have a fair chance of having a stealthy nozzle modification, despite the lack of such experimentation on their side, compared to the US, but nozzle aside they have to shield the engine first, if not nozzle treatment will be useless
i wont worry about 2D/rectangular/stealthy nozzle in J-20, let's leave CAC at that, we don't have the parameters
i'd prefer to see if it's underpowered or not
Reproduced Defense Commentary: China's first aircraft carrier platform, the mystery of the engine

Phoenix Military Defense Commentary August 15 August 14, China's first aircraft carrier platform successfully completed the first sea trials, this is a landmark event with. Chinese aircraft carrier platform trials successfully, that the aircraft carrier power plant basically been solved. However, China's first aircraft carrier to use what force platform, is still a huge mystery. "Kuznetsov" was bought by the Chinese before, there is the legend that the aircraft's power system has been dismantled together Western and Ukrainian. "Kuznetsov" was from the Ukraine towards the whole of China is relying on the tug, slowly sailed on the ten thousand sea miles to arrive at the destination, the level of hardship can be imagined. As the ship lacks its own power, the Turkish side had refused their order through the Black Sea straits. According to the original design, "Kuznetsov" was used in the four 50 000-horsepower steam turbines, to ensure that its speed can exceed 30 knots. Such power is also used for "modern" class destroyers, which uses two 50,000-horsepower steam turbine. That, "Kuznetsov" aircraft carrier power plant is the double of the "modern" class destroyers. If China imports such a large ship engines in the international events is not able to confidentiality, so you can rule out the possibility of re-imported from Ukraine. The Chinese-made ship with the original steam turbine, have not been able to reach this level, 051 series of destroyers equipped with the steam turbine are about 25000-36000 horsepower. Therefore, China's first aircraft carrier platform using the engine, if we adopt the domestic power system, can only be a new development. On the other hand, a huge volume of steam turbine, usually ships into the water before the installation is completed, replace the power system if you must re-enter a large dock for the "surgery." "Kuznetsov" was coming to China although the dock has been repaired, but moved in "major operation" signs. In addition, a separate waste vessel for the development of high-horsepower engine, does not seem reasonable. Therefore, there may be another historical truth! That is, "Kuznetsov" was the engine has been retained. Part of the memoir has pointed out, "Kuznetsov" was launched, the entire drive conventional steam turbines and has been placed inside. More images in accordance with the words, is already on the position of the engine, but no mounting screws. According to the follow-up memories, "Kuznetsov" was the power plant before the sale of China, met with Ukraine's "removal." But this "removal" was very subtle, in the end is all clean "demolition"? Or just remove some parts? As the huge volume of steam turbine, the so-called "complete removal of power system" is almost impossible, coupled with lack of funds and skilled workers at Ukraine, it may be just "cope with errands," like some parts removed, not even achieve the basic damage. Therefore, the "Kuznetsov" was restored power systems have adequate conditions. As the Chinese navy, "modern" class destroyers and the power system, "Kuznetsov" was a homologous series, which has a reliable repair at the reference object, if necessary, import or production of some of the equipment parts on their own, without having to import complete steam turbine. "Kuznetsov" was after so many years of restoration work, restoration of the number one focus is likely to focus on the power system. In fact, both China successfully developed its own self-healing, or that high-powered steam turbines in the technology sector are huge achievements. Although the steam turbine as advanced gas turbines, but for tens of thousands of tons of large ships, however, it solved the problem of power system availability, and for the continued development of China's large warships provided valuable technical accumulation.

I dont know about the impact on performance, but i think that the fuselage would have to be redesigned to acommodate 2d nozzles
the flanker 2d nozzle was a soviet era program developed in 1990. The fact that russia since then has not followed up on this tech but went on to develop 3d nozzles tech, makes me doubt that they will adopt 2d nozzles for T-50. But i could be wrong. Who knows?
See post nº 276 for 3 pictures of this nozzle:
Yeah. Real crude and heavy. Compare that with F-22 which flew for the first time that year
