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

[by78]

It's a 23m flying behemoth based on Mig 1.44 blueprint, with F-117 stealth material and stolen F-35 data

The best David Axe imitation I've seen in a long while.

That's what Chuck/his professor was talking about.

Didn't engineer and mig29 debated the sears-haack body to death and then some couple years ago? Lol. Too lazy to look it up. I have to admit I wish mig is still around but it is what it is.

Yes, and mig had no idea what he was talking about.

I have never posited that more or less is better.

Well, no you didn't but it was probably implied.

Would you please specify which professor and which university?

Bud Schlack, UW Madison.

I would say the plane with fewer control surfaces would have a better RCS in that case, but I think the most important thing to consider isn't the number of control surfaces but how many planes there are. This isn't to say that we should conclude the J-20 definitively has a worse shape or performance than the F-22's, but it does suggest that the J-20's design might involve more complex computations and other considerations.

That's were J-20 has the advantage of being designed more than a dozen years later so able to make use of very much more powerful computers and likely also using better software in that process.

Computational power has an inverse relationship with heuristics in design.

Yep. Literally nothing has changed about that engine nozzle. It seems that the engine has moved more inboard though, and that black ring housing is gone.

Yep, area ruling.

Sigh..... Even when designing a system at this modernity and advancement, backwardness of engine development still is a major bottleneck.
So on the contrary, if there's no engine problem, that means J-20 could be shorter relative to its width? Hence focus more on maneuverability instead of speed and super-cruise?
