    China ramping J20 stealth fighter production and should have improved WS-15 engine by 2019
    | October 24, 2017 |

    China’s Air Force released on its weibo social media account two pictures, which show four J-20 stealth fighter jets flying in formation.

    As of 2017, it is reported that control system, stealth coatings and hull materials, and infrared sensors still have technical issues as does the reliability of its WS-15 engines.

    Some prototypes use the 14-ton thrust derivative of the Russian AL-31 or Chinese Shenyang WS-10 turbofan engines as they target 2019-2020 for all J-20s to use the 18–19 ton WS-15 engine. The WS-15 will enable the J20 to super-cruise without using afterburners.

    A Chinese aviation engineer told China Military Online on March 13,2017 that they are optimistic that the new WS15 engine for the fifth-generation fighter aircraft will be ready soon. The engine’s development is proceeding well. They also have begun to design a next-generation aviation engine with a thrust-to-weight ratio that is much higher than that of current types,” he said.

    They were still working are able to develop the two most important components in an advanced engine — the single crystal superalloy turbine blades and powder metallurgy superalloy turbine disks — but in mass production, the products’ quality is not very satisfactory.

    There are online reports that China will deploy 4 air regiments of J-20 fighter jets by 2019. There are 96 fighter jets in 4 hinese air force regiments. It takes less than 3 years for China to build that many J-20s. In 2016, China had two J-20 production lines, one producing J-20 with Russian AL-31 engines and the other producing J-20A installed with China’s WS-10B Taihang engines.

    A third production line has recently gone into operation to produce J-20A. As each line makes one J-20 a month, their combined production capacity will be 36 a year.

    By the end of 2019, there will be a fourth J-20 production line for trial production of J-20B using China’s homegrown WS-15 Emei turbofans.

    J-20B is an improved version of J-20 installed with China’s new homegrown powerful WS-15 Emei turbofans. China has already developed WS-15 all-direction vector turbofan with thrust-weight ratio of 10. The turbofan is now undergoing intensive tests and will be ready to be installed in J-20B by 2019, an improved version of J-20.

    If the WS-15 meets design goals then J-20B’s cruise speed will be Mach 1.8 and maximum speed exceeds Mach 2.2. Those would equal the US F-22. China will produce 500 J-20B, more than the future total number of other fifth-generation fighter jets in Asia-Pacific.

    The US F-22 was in production for 15 years (1996-2011), at a rate of roughly two per month during peak production. China would be about 23 years behind US jet and jet engine technology. China could possibly achieve in 2019 what the US had in 1996). China stole US F22 and F35 designs and technology. Around 2030, China could have 500 J20B and 100 J20 and J20A stealth fighters. The US would have 185 F22 and perhaps 1500 F35s.

    About 66 F35’s will be made in 2017.

    In 2021, full production rate of 150 F35s per year is planned.

    The J-20 likely has inferior stealth to the Lockheed Martin F-22 Raptor stealth fighter aircraft or the F-35 Lightning II fighter. The J20 lacks thrust vectoring and is likely less maneuverable than American-made fifth-generation warplanes.

    Russia has developed 99M1 to 99M4 improved versions of AL-31F, but China has also developed improved versions of WS-10, named WS-10A and WS-10B better than Russian ones with thrust-weight ratio of 9 than Russia’s 8.

    China has a third-generation single-crystal blade used in WS-10B. It is reported to withstand 2000 degrees which enables engine life to be increased from 800 hours to 1,500 hours. This would be close to maintenance overhaul interval of western engines.

    As reported above J-20 in many iterations is progressing well & a good version in J-20B would be in service from 2019 onwards with new WS-15 engines (possibly with thrust vectoring), improved stealth, avionics & sensors, flight controls.

    If members would recall PAF had said years ago that it is interested / acquiring F-20 from China. By this it had meant improved J-10 as J-20 was nowhere in the picture. So perhaps the time has come to acquire FC-20B & possibly setup an assembly in Kamra!!!!!! Wishful thinking!!!!!

    I'm preeeeety sure that the j-20 and fc-20 aren't the same thing. The fc-20 is a J-10 variant, not a j-20 variant.

    https://en.m.wikipedia.org/wiki/Chengdu_J-10

    @waz can you please fix the title? There is no evidence to support it.

    India probably has nothing to worry too much about. Most of the fighters will be based in locations to protect against US and Japanese forces, and to a minor degree, Russia. Very few will be dedicated to facing India, and China will mainly field it's 4th Gen fighters against India.

    Pardon my ignorance but i could not find where exactly is "PAF may acquire J-20b 2019 on wards is suggested in the article? In fact I did not see even PAF written anywhere in the article?

    I think FC-20B means J-10Bs !!!!!!!!!! PAF will not go for J-20 that early(2019)........ May be Mirage replacement is coming at MAX.......... That's it.

    "MAY POSSIBLY ACQUIRE" wording explains everything.

    J-20 deal has been made we would get the Jets when we want. I also think we are waiting for WS-15 engine to come before we go for J-20

    china is the second country in the word that has produced stealth fighters after US. china is surely the next super power in the making. US has been sensing it for some years now. many people predict that israel will be the next super power but i think china is the favorite to take that position. their military and economy is much larger . they have the land area and enough human resource. above all they have been doing things with a vision to slowly conquer the world without firing a bullet. but US wont hand over them the position without putting up resistance and that resistance can even lead to a full scale war. the US-NK tension could possibly be a step in this direction at china's doorstep. US forces in afghanistan are also meant for china. so be careful china.
    On topic chances are there that PAF may go for a some squadrons of these jets. it will be a compulsion for the PAF. we are not going to get more F-16s. european jets are beyond our budget range. even chinese stealth jets wont be cheap but with the induction of rafale and upgraded su 30 in iaf and that too in massive numbers paf wont be having any choice. PAF is is desperate need of limited numbers of 5th gen jets to have some qualitative edge . off course paf cant match the iaf in numbers.
