J-20 5th Gen Fighter Thread V

Another prototype, I thought its already LRIP

A new baby...J-20 (2017)!

Ahhhmm why a new Baby ??? That is simply prototype 2017.

wow...
A six-frame J-20 photos, detailing open-cyclic lifting moment. Can see the deflection of canards and a lot of swirl, excellent aerodynamic features.....

Oh no, he'll have the rest of his life to do so because falsehoods can always be spread.

I exaggerate the cost of integrating WS-10 into J-20? Really? Do you realize that you need new air-frames are needed for testing a new engine, right? The inlet shaping, internal load-out, engine area, (possibly the areas around the engine as they need to remain stealthy despite different heat output) all have to be re-optimized. These are hand-built unique frames, not production frame cost. How much do you reckon they cost? You can't make do with just 1 because you'll need to take what you learned from prototype 1 and build them into a second one. Maybe a third design if you learn even more. How many frames per step? (The more the faster the process.) Just the air frames are running up your costs into the 9 figures unless you wanna take 10 years conducting all your tests with 1 frame per step. If you wanna take that long, your engineering team costs will be high. And where will the WS-15 be by then? 10 years later, you'd have WS-15 running on J-20 making the whole WS-10 project completely pointless. So you'll need many air frames to get the job done quickly... cus you really wanna stick it to Majumdar LOL You'll need how many engineers? They all have to be paid for the duration of the project. They can't work on other projects that might actually be useful during this time. How long will this project last? J-10 1035 with WS-10 showed up how many years ago? And now we still don't see batch-production of J-10X with Taihang and J-10 is a much simpler design than J-20. Nightmare project...

It will take years, massive man-hours, and billions of dollars to do something that is not useful. I stand by that statement.

Ho, ho, ho...

目前负责生产的中航工业成都飞机工业（集团）有限责任公司有2条歼-20生产线，一条是生产歼-20的基本型，装备俄制AL-31发动机；另一条是生产歼-20A型，装备国产WS-10B太行发动机。

报道称，为加快生产速度，最近已加开了第三条生产线，同样是生产歼-20A型战机。3条生产线各以每月一架的速度，年产量共36架。扣除已生产12架早期量产型机，剩下84架的生产目标在两年多便可完成。

First of all and English translation please and second, if it is that BS concerning two different production lines at CAC for an AL-31FN-equipped and a WS-10B-powered version, so simply forget it.

There are no WS-10-powered ones as yet and it is even more idiotic to think CAC would build two different subversions of the same type at the same time. Not even with the J-10 thy do or did so.

I seeing multiple sources saying that.
Are you sure all those are BS?
I mean like the case of Engineer are so sure SU35 is BS, well now we know how it goes.
I don't know, usually, when there's smoke, there's fire.

Multiple sources said the J-20 200X demonstrators were using WS-10s even though we had near definitive evidence that they weren't. Beware argumentum ad populum.

 

[Hyperwarp]

2 different lines one with WS-10 other with AL-31F? Huh? I doubt thats going to happen. F-16 was one aircraft that flew with 2 different engines at the same time but I doubt the PLAAF would want to go for that solution.

The early demonstrators 2001/2002 were rumored to be powered by basic AL-31F with 123kN thrust, but prototype 2011 onwards had different engines. Maybe from 2011 to 2017 they tried different engines. Maybe one of them was tested with WS-10IPE but honestly, none of us know the answer.

Why would you insert a paragraph you read from somewhere without including the source or link? And then say "ho ho ho" as if it was self-explanatory that you got hard evidence? There are too many BS articles out there. I can find you a source that says China is ready to induct J-23 and J-25 if you like. It's completely untrustworthy and full of shit though. I think that after all this, everyone telling you, you just can't see that the merits of a Taihang powered J-20 are just too small for the effort needed. You just wanna see a Chinese engine in J-20 so badly, you don't care what it takes or what it is. People with cool heads wanna do this right and they wanna put WS-15 in it when it's ready. They don't wanna waste time on vanity projects to spite some articles on the internet.

For me, if I see J-20 start to use WS-10X, that's a very troubling development. Because that indicates that they have run into serious snags in WS-15 development and that it is in jeopardy of abandonment.

Put WS-10B in J-20? I got another Majumdar headline for you: "Chinese 5th gen engine development fails; Chengdu resorts to using underpowered old Chinese Flanker engine copy for J-20." Ho ho ho

Do they have smoke pods on these or something???
That really does not look like a vapor trail.
