Chengdu J-20 5th Generation Aircraft News & Discussions

[Mangus Ortus Novem]

The purpose of J20 and other Chinese pltaforms is the security of the state and protecting sovereignity of the Chinese people.

What matters is that these platforms do their job.

Everything else is distraction after that.

Surely domestic engines are coming up fast.

They will be powering the airframes.

Academic arguements are that- academic.

In order to ensure peace and stability whatever can do the job is great.

Everyone has learned from someone else. Which is a good thing.

But most important thing is: Where is J31 2.0?

 

[Ultima Thule]

No .. I beg you in return to give us one single evidence. Otherwise go bach thru thrse pages i already posted my conclusions several times. There is simply NO ... Not a single external detail loke nozzle design, pedal length even the sound is so ...

The only ones with wet dreams like you say are fan boys, dreamers ...

just your wishful thinking and wet dreaming, it might be anything their WS-10 or AL-31, you does not have any prove that it is not WS-10, you are ranting against china's engine development

What is your definition of proof? Chinese physics or you want a Chinese official to say it?

The Russians are plenty of proof.

no no 'Indian physics'

You could be the first.

Do you think that what I speculated, applicable to any 'stealth' aircraft from any country, is TECHNICALLY valid ?

I am not saying that my speculation is true, because unless the creators of these aircraft publicly confirm we will never know. What I am asking from you is if what I speculated came from a solid technical foundation. Remember, I posted proofs of that technical foundation from a Chinese paper. Not US. Not Russian. Not Indian. But CHINESE.

Bro, you have a right to question things, no problem, but whether it's stealthy or not, it's up to the Chinese to decide, they have access to current radars, let's fly the thing in front of it and see if it works, if it doesn't, improve it. Personally, I think there are technologies that can detect stealth but that too to a certain degree. Else, why do you think all major power want to develop it?

You are avoiding my question, which I fully expect from a PDF Chinese.

I did not asked if the J-20 is 'stealthy' or not. That is not up to the Chinese but to the laws of physics. A clean F-16 is the unofficial crossover threshold for 'stealth'. Its RCS is roughly 1 meter squared at most usable radar freqs. Whether the J-20 is below this threshold or not is up to measurement data, which the Chinese are not going to divulge. It maybe higher, we may never know. To this day, we do not know the true RCS of the retired F-117, let alone the still active duty F-22 and B-2.

But I did not asked about the J-20's RCS. I asked if my speculation regarding the creeping wave behavior and how the radome designs of the J-20, F-22, and F-35 are affected by that behavior. I have provided a paper from 3 Chinese engineers who verified that the creeping wave behaviors exists. The creeping wave behavior is what your fellow Chinese charged that I made up. But oddly enough, three Chinese engineers mentioned it in a conference.

I can see that you are practically TERRIFIED to admit that my speculation on the radome design may have solid technical foundation. It is not that I could be wrong. It is only that I DID NOT speculate from nothing. If you admit that my speculation regarding the radome is technically feasible, then it is possible that the J-20 did came from the MIG 1.44 project, an idea that you guys loathe to even consider.

Dude, whats wrong with you? I didn't even attempt to answer your question, I am no stealth expert, I am just telling you to stop typing so much. It's really annoying, none here are stealth experts, let alone you, we just want to know what are the latest development for J-20.

If you believe it doesn't work, then good for you. Please don't flood this place.

To be honnest my very first thinking when I saw this word was "What a bullshit".

So far absolutely nothing credible brings to this assumption, since I followed the pre-study of the program since 13 years.

you mean China can't invent, innovate new thing but US can what loser you are you are ranting against China, as usual AMERICAN superiority complex and baseless thinking that J-20 was develop from MIG-1.44

 

[S10]

It is not just I who made the accusation, son. There are plenty of aviation specialists who made the same. With my experience, I chose to ally myself with them. You are asking for, basically, an impossible task. We all know it is impossible because China is not going to release any information about the J-20. This leave you to demand that we all accept your position as default. That is not going to happen. Just as we do not have any concrete proof that the J-20 came from the MIG, neither do you have any proof to support the contrary. You may say that in the end, it is just opinion, but also in that same end, not all opinions are equal. Some have more weight than others. Yours, for now, just weight as much as a soap bubble.

If I said you're an idiot, I should have to prove my case (though there are plenty of evidence around). You're making the claim that J-20 is copying off of Mig 1.44, thus the onus is on you. What you're trying to argue is reverse onus, a logical fallacy.

Since you can't provide any real substance other than pulling crap out of your ***, I'll just chalk this down as your usual BS.

Basically the Eurofighter came from the Mig 1.44

This is a completely different design not because they have similar squared intakes so it means they copied the Typhoon Design from the Mig 1.44

no sir he don't understand, he always think that China steal, copy and paste, and doesn't have the capability to invent and innovate something new what a loser he is

It's still a mystery to me how we managed to steal the fastest super computer from the US and bring it all the way back to China.
