J-20 5th Gen Fighter Thread IV (Closed to posting)

[kyanges]

What facts?

if i go for facts i will not even consider your opinion, first because i would only trust what Chengdu says officially, and only very but very few officially released data by the PLAAF.

Here we spent pages and pages about how much J-20 weighs, or its dimensions?
and tell what is the official version?

here none all is opinions.

Tell me facts?


Do you have the computer and wind tunnel data of J-20?
Do you have blue prints of its engines?
can you explain me with detail its avionics?


All what we do here is opine, unless we would work at Chengdu we are basicly fans.


If i would see only facts believe me i would not even opine here i would only see pictures, not even opine about the pictures.


When we opine we need basics of aerodynamics, at least to know how stealth works otherwise, it is better no one opines unless we have Chengdu official data.

Basic of metalurgy and chemestry. in reality this is not a school, most people what we do here is just opine upon our experiences and interests.

If you have ever worked in the aerospace industry, being a pilot or mechanic, or at least study an engineering you know the world of aerospace is basicly science.

Just to calculate roll rates or pitch rates you will need basics of algebra and trigonometry.

So honestry if we only want facts i will only wait for officially realeased data, and i would only see pictures without opine about them

I think perhaps the issue is we should not go so deep, and let other things come up like picture and other things like first flights etc, i think that is what the moderators mean.

Yes, this! .

Likely fake ?

 

[SteelBird]

Surely fake. No way that J-20 test fire anything at this phase.

absolutely fake, if it weren't for the photo shop and conjecture on the J-20, there would be no thread, the official news on this bird would be hard pressed to fill a teacup. The theory behind the J-20 and its aerodynamics may have been well illucidated, but some still seem to be missing the essence of this aircraft. It has been designed as a fifth gen aircraft to counter the F-22 and to a lesser extent the T-50. The canard was choosen as the eng says to enable it to achieve high AoA in order to turn with aircraft equipped with TVC, which does in fact enhance pitch transitions, and roll rates. To forbid or stiffle the discussion of these elements would render this thread the same boring blah, blah, blah, that proliferates on the internet at large, and I would have been gone a long time ago...I have zero interest in a news thread, filled with peoples opinions on said news thread? Mig is right on this issue, this is a thread for people who want to learn and debate the various design elements and theories, and how well Chengdu is/has met those theories. AFB

Whomever is photoshopping these images, is very very skilled.

One thing that immediately tells us that it's not a real picture: The missile should have been fired after the door had been closed (as the door should have had enough time to close while the missile is locking on the target).

That wouldn't tell us. After all, the animation showing the firing sequence in which the door opened, rail extended, door closed, (Missile locking on all the while), missile firing, door opening, rail retracting, door closed was just speculative. As I think Latenlazy pointed out either in this thread or another, it's still possible that the door can also stay open while firing.

Not saying that it's one or the other, just that both are possible.

Yeah, that is a possibility. But as they say, it's possible but not likely, because going by what we currently understand how things work better aournd there, the door should remain closed whenever possible. So I'd go by that logic until we know otherwise.

On the other hand, looking at that picture, I was thinking: How much would the missile exhaust getting into the intake affect the engine?

 

[drunkmunky]

I'm still quite confused about the operation of the launching mechanism.

If the launch mechanism activates with sufficient speed, the time the door is open, launch, and closes should be fast enough to mitigate an increased RCS signature.


The setup that we all believe, requires the door to open, launch mechanism comes out, closes, AND THEN, Opens, closes again, is 2 operations.

Wouldn't those 2 motions and door openings increase RCS just as much as keep the door open for a single operation?

Also, the complexity of the system increases....

I don't see the positives..

When the fighters have to use the sidewinders, the planes are already in eyeball range. Stealth not longer matters
