China’s Fighter Export Prospects Remain Uncertain

The non-appearance of the Shenyang FC-31 fighter at the recent Zhuhai Air Show is another indication that the type is failing to fulfill both technical and sales expectations. However, the aircraft’s Russian Klimov/Sarkisov RD-93 engine was shown for the first time. This led some observers to believe that this was part of a joint Russian-Chinese initiative to sell the FC-31 to Pakistan, since the same engine powers the Chengdu JF-17/FC-1 fighter that China has co-developed with Pakistan.
Some Chinese industry officials said previously that the FC-31 would be a “breakthrough export program.”
But sources within the Pakistan Air Force (PAF) delegation at Zhuhai stated there is no realistic prospect of the service acquiring the FC-31 for now. “We need all of the resources that we have at the moment for the JF-17 program,” said one PAF officer. “The FC-31 failed to make an appearance this year at Zhuhai as it did in 2012, which may be at least partially due to the fact that there are no near-term customers for it,” said an Indian military aerospace analyst.
The FC-31’s flying display during its debut at the 2014 Zhuhai airshow suggested that it was underpowered. Shortly thereafter, there was an announcement from Russian industry that the Klimov engine design bureau would develop an enhanced-thrust version of the RD-93 engine to correct that shortcoming. The current RD-93 is a reconfigured version of the Mikoyan MiG-29’s RD-33 engine that has the accessory pack moved to the underside of the engine.
Meanwhile, Pakistan is focusing on how to improve the JF-17 by modifying the airframe and changing some of the onboard systems for more advanced options. One of these could be the replacement of the current Chinese-made NRIET KLJ-7A radar with another model, potentially even an AESA.
While China’s military industry is trying to sell its products to foreign customers, its own air force continues to purchase front-line aircraft from Russia. The PLAAF has been trying to procure the Sukhoi Su-35 Super Flanker for more than 20 years. The deal that is in place now was agreed only after protracted negotiations. The contract that was finally signed was for 24 aircraft, a concession by the Russian side, which had initially insisted that the Chinese purchase at least 48 aircraft.
News from the Russian delegation at Zhuhai was that the first four Su-35s could be delivered by the end of this year. But, some Russian specialists at this year’s show who are familiar with the subject were skeptical. Said one: “
There is a concern that the Chinese purchase of the Su-35 is only so that their industry can gain access to the [NIIP] Irbis radar and the [Saturn/Lyulka 117S] engine, in order to copy them. This fear has never gone away and only continues to grow as the delivery date gets closer.”
According to other members of the Russian delegation at Zhuhai, there are active efforts by Chinese industry to increase the resources that they devote to improving their own indigenous designs of both airborne radar sets and jet engines. Any subsequent effort to reverse-engineer the systems onboard the Su-35 will give a major boost to those efforts.
Some of the same Russian officials question whether China will ever become a major exporter of combat aircraft that are original designs, or if the country will continue to be dependent on a “technological umbilical cord” from Russia to sustain its innovation.

Não é isso que dizem, mas sim que o dito caça pode não ser tudo o que se espera pelo simples facto de que a China está a comprar mais caças Russos e que provavelmente continuará a ter grandes falhas no desenvolvimento de algumas tecnologias locais (ex.: motores).
Realmente é louvável o esforço chines para se colocar entre as super-potencias, mas ela ainda não dominou muitas tecnologias sensíveis, daí continuar fazendo compras da Rússia, vide a atual encomenda dos SU-35S. Assim este avião, se for para ser feito sem a ajuda russa, ainda vai demorar a se tornar operacional.

Photographs have begun to appear on the internet showing the first flight of the second prototype Aviation Industry Corporation of China (AVIC)/Shenyang FC-31 ‘Falcon Eagle’ fifth-generation fighter.
Compared to the initial prototype, the second FC-31 — sometimes known as the FC-31V2 — features extensive revisions, apparently including a revised, F-22-style forward fuselage including single-piece cockpit canopy, and re-profiled tailfins.
Previous rumors suggested that a second FC-31 prototype might have been adapted to meet PLAAF requirements, perhaps leading to a production-standard J-31.
The maiden flight occurred at around 10.00hrs local time.
Program history
Reportedly officially designated Project 310, the original prototype ‘31001’ is a technology demonstrator built and reportedly financed as a private venture by the AVIC and Shenyang. The aircraft was officially named FC-31 ‘Falcon Eagle’ during the Zhuhai airshow in 2014.
Pakistan is reportedly very interested in this twin-engined ‘fourth-generation multi-purpose medium fighter’.
In addition, there are still strong rumors concerning secret PLA participation or at least an interest in considering the J-31 as a future land-based and carrierborne medium-weight fighter to complement the larger J-20. In theory, it could even replace some of the remaining J-7/8 series fighters while complementing the modernized fourth-generation J-10 and J-11 fighters.
Shenyang has previously shown a model of how an evolved J-31 design could look like. Featuring a number of major changes compared to the demonstrator, this updated design includes radar cross-section improvements such as clipped wing edges, revised vertical stabilizers, a re-profiled forward section with a single-piece canopy and an EOTS similar to that on the F-35 or the latest J-20 prototypes. A new engine was represented by redesigned, stealthy nozzles. This is said to be a ‘new’ Chinese 10-11-tonne thrust unit that will ultimately replace the Russian RD-93. Exactly what this engine is remains unknown.

Salvo engano, acho que o IOC da versão operacional está agendado para 2024. Mas posso ter me enganado com as siglas. Não duvido nada que se ele arrumar um comprador antes disso ele terá o aval de Pequim para começar a voar antes do tempo em alguma força aérea mais afortunada.
A ver.
ps: o que parece ter mudado neste segundo protótipo são os estabilizadores verticais. Mas se me lembro bem, o mock up que aparece na Air Show China desde 2014 apresenta asas e estabilizadores vertical e horizontal alterados. Aparentemente as entradas de ar também foram modificadas no mock up mas isso não é possível de se perceber nesta foto. As modificações estão sendo feitas, aparentemente, a conta gotas e com muito critério e cuidado.Afinal, é um projeto "privado", e sem bandeiras para custeá-lo. Qualquer erro neste momento pode sacrificar o avião por inteiro.

Gostaria de ver um J-31 ocidentalizado como motores GE e aviônicos ocidentais.

As turbinas que hora estão sendo oferecidas são modelos novos da Russia, Ucrânia e um modelo ainda em desenvolvimento na própria China. Nada de ocidental.
Quanto aos aviônicos, eu creio que só muito $$$ faria com que os chineses abrissem mão dos seus no caça. Mas há clientes e clientes. E como até o presente momento este caça parece destinado a exportação, e não as ffaa's chinesas, talvez isso não seja exatamente um problema.

Agora tentem imaginar esse 'baixinho' com fusão de dados, TVC, super-cruzeiro, steahlt, radar aesa, e outras similitudes da 5a G...
Vai ser o must.
