The article that originally was discussed said " J-20 has a 25% smaller wing than F-22"
So 73 sqm is 25% smaller than 78 sqm...wait what?

Just to remind you, a large part of the Su-57's reference area is also over the fuselage. But you conveniently ignore that.

Your credibility is dropping faster than a spacecraft reentry.

The F-22's 78 m^2 is *reference* wing area, *not* exposed wing area. So is *every* wing area figure for every fighter you will find, including the Flanker. You are trying to compare the length of a cat with its tail against the length of a cat without one.

1) you are comparing the wings of the J-20 with those of a Flanker in the above image. You need to show numbers of those wings.

Simply showing images is useless. The two types of wings have different shapes. That means eyeballing is impossible.

Even if they have identical shape, eyeballing is a bad idea. I specialize in super resolution imaging in my line of work. And one of the things that we do regularly in the lab is to compare sizes of various organelles in cells. So I am in a unique position to tell you how dangerous eyeballing can be. We take tons and tons of images of cells first and analyze/quantify them later. Obviously, we stare at the microscope and computer screen while taking images and naturally would get an impression of the size distribution. I will tell you with 120% certainty that that first impression we get by eyeballing those images means absolutely nothing. The later quantification using sophisticated software usually does not agree with our eyeballing.

So simply put, get the numbers.

2) the article in question has been concluded to be full of holes. It misquoted Deino and deleted his comments. So the article should be dismissed altogether.

3) with the time you've spent typing long paragraphs, you could easily find a software on line and measure the wings. It takes less than a minute. Do it and show it.

Using reference wing

Su-27 has longer lex making for a longer root chord and due to longer wing span the wing was bigger reference wing area;)

You're contradicting your own diagram. Not sure which, but you're either being stupid or shameless.

of course you never counted the Su-27 has a compounded wing with a very long LEX with cambered section haha, it seems you can not swallow your mistakes ;) what it has lex haha you have to always consider the LEX because the that is called wing leading edge root extension haha

The J-20 is also a compound wing by your logic, and the F-22 isn't. With your style of argumentation we should claim the J-20 has more wing area than the F-22 :rolleyes:. Either way, that has nothing to do with the reference wing area. You're just making stuff up at this point because you can't admit you were wrong. You got caught contradicting yourself and now you're accusing others of making a mistake. That's just rich.

Too much blah blah blah, the J-20 has a smaller wing because the aircraft has a very long fuselage, if it would had a wing as big as F-22`s wing in proportion its wing would be enormous, but draggier, thus the small wing is aided by the canards, thus reducing the need for an aft tail, thus making for smaller tail and making for a lower drag wing, the solution is quiet logic since the fuselage from radome tip to nozzle end is around 20 meters, while on the F-22 it is around 16 meters, the long fuselage requires a small wing to reduce drag specially since its wing is further aft than comparable aircraft like Gripen, J-10 or Rafale however your obsession that is a dogfighter is a dogfighter blinds you, with good engines it might have good sustained turn rates and good weapons and sighting systems will be like F-35

Yano what isn't blah blah blah? Measurements. Numbers. Where are they? Oh you don't want to provide them? Then take your own advice and stop blah blah blahing.
