SAC FC-31 Stealth Fighter: News & Discussions

Because the F-35 design is most optimized for SVTOL, and pays the price in terms of acceleration, range, and max speed.

China didn’t take all aspect of F-35, beside the DSI intake, I’m pretty sure this J-31 has several hundred hours in wind tunnel tests to tweak the design to meet military planner’s wish.

The Chinese engineers may not have had a choice because the F-35 is a highly draggy design that needed 40,000 lbs of thrust.

That’s why we go with two engines...if China can have F-35’s engine...might as well to copy integrally F-35 with VTOL...we need similar F-35 for carrier too but it’s a wet dream

But two engines take up more space, leaving less room for fuel. The F-35 with 8.5 tons of internal fuel gets only 590 nm combat radius; and it is actually failing to achieve that range target. If the Chinese F-35 has two engines, then its fuel capacity is even lower.

Don’t forget it’s slidely bigger that F-35...the fuel tank will be enough for the mission

The better solution was learn from the F-35 data and design a new airframe that fixes the design compromises of F-35, but the Chinese engineers decided to not to take that path, as it appears that stealth and time to market were more important than the most optimal airframe design.

Than show us how the aircraft should be look like if you’re so convincing that the J-31 airframe is wrong. Make some hand sketch...will just fine but do it in Pro/Engineer or Solid Work is even better

Indian fools think that only by being exposed to Western technology can other's progress.

Wait till 2020, with both the J-20 and J-31 in Chinese service, and see them p*ssing in their pants, as all they will have will be low-tech Su-30 and Rafale fighters and maybe that supposed 5th generation PAK-FA which looks very non-stealth to me

You gonna get bombarment from them for your insult of their mighty PAK-FA

1. You are being too harsh on the F-35.

It is not just me, the western world is full of F-35 critics.

You make it sound like a complete failure with no merits at all.

It is.

2. You are not giving the Chinese enough credit. You are assuming that the Chinese basically stole the F-35 design,

Chinese F-35 design data hacking is widely reported in the US. According to sources, Chinese "took the whole thing", and now you are witnessing the result.

You are assuming that even after the F-35 was done and many flaws analyzed,

They may not have done this.

the Chinese still incorporated them almost deliberately.

That saves time and money.

Basically, you're saying that you could have made a much better plane if you headed the project.

It depends. If your project has money and time, then you would try to find an optimal solution. If not, then you copy and paste.

Shenyang and Chengdu do their businesses quite differently and these differences are reflected in their product.

Chengdu, the maker of J-20 and JF-17, creates partially or wholly original aircraft. Whatever the jet their models were based on, Chengdu takes its time to do the R&D and the end product is significantly different and unique, representing a Chinese solution to a problem.

Shenyang did license/unlicensed production of Russian jets for most of its history, and their models differ little from the Russian originals externally. And Shenyang decided to get into the business of replicating western jets, starting with the F-35.

The F-22 was full of critics also, this is why they need to keep projects like the b-2 secret imagine if the b-2 was in the public domain it would of gotten hard bashing.

Can't be serious...China took the whole thing? ...than it's worthless for US to continue with F-35 because Chinese will be able to design an fighter to counter it. I'm wondering why they still push forward and continue F-35 program, is there a rational explaination?

Much flatter than the F-35, creating less frontal area for drag.

The F-35 is basically an A-35, an attack jet that flies under the protection of F-22 and F-15 Golden Eagle(An upgraded F-15 with latest AESA radar and avionics).

 

[Pak47]

Is

J-21 and J-31 same thing? (is it just typo?)

The snowy oil and this look very similar.

 

[Korean]

The F-22 was full of critics.

F-22's critics criticize about its cost and oxygen problem, not its performance in air. The F-22 is truly one of a kind jet.

Something tells me that you don't know much of aerodynamics. I don't either.

 

[SOHEIL]

Hollllly Sh!T !!!

J-31 !!!???

 

[Korean]

No one knows what its official name is. But yes, J-21 and J-31 refer to the same jet.

The Yf-22 times they were criticizing it during the gulf war saying what is the use of this f-15s can already do this.

So who criticizes the F-22's combat performance? No one.

Yes they were, when 1 f-22s go into combat with 4 f-15s that shut their mouths, lesson is don't listen to critics.
