That twitter post is wrong, the UK has better and stronger cap abilities to make jet engines than France does !!!!!!! The French have nothing that can compete with Rolls Royce.

If you look at all the instability in the world today, it does to me feel like the Americans are taking down all the variables that would interfer with its title fight with China for who is boss.

That war is coming, and I think it will come soon while the Americans have the advantage militarily. The USA wont let China's plan mature before acting. China has to make that calculus to be ready for a war that will be imposed on it.

Is Venezuela about to undergo a regime change operation? So, it Looks like it to me. Venezuela is a variable that will interfer as it is not American aligned as of now.

The whole Middle East will be run by Israel soon.

So, China will have to upgrade her manufacturing rate to get to an ideal fleet size that poses a real deterrence to the USAF soon, even if that means it is not the perfect fleet that it was planning. So, upping the J-35/J-20 fleet as of now would make the most sense while the 6th Gen platforms go through their development and maturity curves.

I could go on ... But this is "off topic for this thread, so lets stop now" .

It is unlikely that China and the United States will erupt into a full-scale war, as that would lead to the extinction of humanity. The manufacturing speed of J-35 will indeed be rapid, as the 6G era is just around the corner. The J-35 is likely to be produced in the hundreds and quickly the PLAAF and PLAN, before turning to foreign trade.
The J-35 has received a great deal of purchase intention, and it will be a very popular foreign trade fighter.

Chinese finally have now caught up with Western fighter engines. I very well expect that in the next decade they will surpass Western engines.

but we don't know lots technical specifications of Chinese engines like MTBO (mean time between overhaul) engine life etc etc

Chinese are relatively new in the designing of aero engines from scratch so don't be so optimistic , I would say Chinese aero engines could reach western standards in next 20 years

They are in fact not! Corrently all operational ones are using WS-10C2 engines.

It was reported from a reputable source as any, but who really knows, unless the Chinese government publicly reveals it as operational and at what performance level. The news on the WS-19 seemed too good to be true, but there is no way to know independently how far along Chinese industry really is, and even at what production levels. We only have serial numbers on airframes and shapes of engine exhausts to go by. As a closer watcher of Chinese military developments, I will defer to you on this one.

Yes, this is so far - at least per my memory - only confirmed true WS-15 ... all others from then one are using the WS-10C2 whih is similar, but not the same. In fact it is more a development like from the WS-10B to the WS-10B3 on the J-16 featuring the longer nozzle feathers.

 

[Deino]

@Deino are the WS-19s on the J-35A? I'm seeing rumors on twitter that the engines fitted are WS-19s and not WS-13E/WS-21, is this news accurate? Is China finally ready with both the WS-15 and WS-19s?

Indeed, it seems so - however the WS-15 is not jet ready - ...

 

[hyperman]

however the WS-15 is not jet ready

hmm.. whats the delay? I thought it was ready months ago.

Well, he is not wrong. What he meant is a military-grade jet engine, not a civilian one. Yes, in the past, the UK did manufacture military jet engines, but I am aware of none in recent years; perhaps you know better. Let me know. They did work on the Tempest engine, but that is in the future. The Typhoon jet engine is the Eurojet EJ200, built by a European consortium, though based on the Rolls engine

It is more or less confirmed cctv 13

UK civilian aviation engine high bypass types are ahead of France. Same can honestly be said of military low bypass turbofan since EJ200 is basically British and is a better engine not just in thrust compared to M88.

EJ200, F119 and F135 (F136 too) adopt "5th gen engine" level technologies.

F414, M88, WS-21, F110, AL-41, WS-10C and more modern are slightly below.

F404, F100, WS-10B and WS-10A, AL-31FN late series and M53 are slightly below.

Then you have your RD-33 variants, WS-13 and early Al-31.

WS-15 and WS-19 aimed to achieve that top tier level as EJ200 and F-135.

Adaptive cycle engines are aside from these but obviously represent the next step. All of these are 0 - mach 2.5 turbofans. F119 runs closer to jet engine bypass ratio while F135 is the opposite and runs closer to high bypass ratio. This class of engine is the most complex and materially demanding.

I'd say with WS-10C, WS-10X (some call WS-10C2) and WS-21, China has already attained F110 and F414 level of general technology with possibly less MTBO rate but this is less of an issue than people want to attribute to it. They'll just have to produce more and 2000 hours vs 5000 hours for US engines is a big deal on paper but in high intensity war, most fighters may not even reach the level to require overhaul of engine. 2000 hours is approaching 100 days of straight flying total. Yes engines are complex, expensive and takes a long time and lots of resources to produce overhaul but high intensity fast paced war is not as demanding on MTBO than drawn out wars.

With WS-15 and WS-19 (apparently the J-35A is already using WS-19) then we're talking F-135 and EJ-200/ F-414 level of technology.

I confirmed this a long time ago. However, some people have questioned it.
I can't speak for anything else. However, on this issue, I definitely know more and more accurately than Yankee.
LOL.

Let me repeat. Only the PLAAF-purchased version equipped with the WS-19 engine can be called the J-35A. This is the only correspondence. Therefore, any PLAAF-purchased version must be equipped with the WS-19 engine.

what engine doest the PlAN version have ? WS-21?
Also when WS-15 is production ready will PLAAF replace the J-10C with it? I know WS-15 and WS-19 wont be exported but what a capability it would be for us if we can upgrade our JF-17 with WS-19 and J-10 with WS-15.

You are correct. Top engine and reliability tech's top 3 are 1: GE, 2: Pratt and Whitney and 3:Rolls Royce. Then you have the French and others. I am sure China will be added to the top 3 list in the future. The engine tech from WS-15 and WS-19 has matured a lot. It'll just need a few years of utilization for data to be released on different metrics.

Considering the WS-15 engines are being fielded on the J-20s, the core technology should be the same for the WS-19.

If the PLAN accepts to field the WS-19 engines, they must have achieved enough reliability, to be fielded on J-35, which will be crucial for the needs of carrier aviation.

Different technology baseline between WS-15 and WS-19. The former was built for heavier platform use with higher electric output.

Its a shame this jet has a canopy bow, and is not single bubble canopy like the J20(the original mock-ups of the FC-31 showed a single piece canopy). In fact, the J-50 seems to have a canopy bow. Reasoning maybe for things like to better protect against bird strikes.
