Popeye agreed to new thread. All future aerodynamics related discussion should go here:

hey i have a question, and this is what annoys me, many of the news reports have aerodynamic points, you yourself had an aerodynamic question due to a video and a picture, then when is the thread moving to off topic?
if i answered you your question, then both of us are off topic?
then it means your question should have been sent to that thread, not even asked here so this is what annoys me, why only leave this thread for pure news, and making separate threads for each news, because this is what annoys me, J-20 is an airplane, its aerodynamics, so if you ask a question like you did comes blitzo if i answer claiming foul, then you should not have asked the question in the first place, and i do not think is fair if some one else answers you the same question call him on topic but if i answer you then is off topic.
And that is what annoys me

can i open a separete thread about doctor song`s paper aerodynamics?
Mig popeye suggested that you start a T-50 thread, like you I am more interested in the turn and burn stuff, but not everyone on this thread shares our interest, in fairness to you, a lot of us are obviously interested in this, and we did kind of draw you into this. So in the interest of love peace and real airplane talk lets try it out. Seige and Player, i.e. any of you guys that had input into a great forum type discussion, I hope you'll try to join us on that thread, to be honest this was the best discussion I have ever been involved in, but my apologies to any we might have offended by hogging the J-20 thread. "Break Now Jester" Brat OUT
To my memory, all the photos of J-20 doing a turn show the same pattern, for which i.e. has an explanation, and Mig-29 seems to have one, too. To my layman's eye, I just don't see any control surfaces doing apparently enough to lift the nose in order for the turn to happen.
i.e. says it's the lift that makes the plane turn. Fine, but that lift has to be more on the nose end and can't be equal on the whole bottom of the plane, or it would only push the plane higher and higher, instead of making it run in circles, wouldn't it?
Or, are some of the control surfaces pushing down the tail during a turn? Otherwise, and again to my layman's reasoning, the plane would have gone off at a tangent instead of turning circles.

sorry wrong thread

there are many people reading SDF, and not everyone into the aerodynamics stuff, there are some who logs flight, or wait for developments, often weeks in between logging into SDF, to find what? the thread clogged by off topic discussion
imagine this spread to other thread, and make someone miss a critical plane serial, they got to be pissed
people like siege and blitzo tries to stay on topic as possible, only commenting to very recent and pertinent image or development, you on the other hand paste a whole article, old ones even, and brings up comparison where it is unnecessary, also drop the big and bold fonts. we can read well you know, and if there is an important point don't worry we won't miss it
now the mod has created an aero thread for everyone, i suggest you use it well
Wait... I know you said it's from satellite photos, but I'm curious specifically who calculated the 18.7 number. Yourself, or is it from somewhere else? A little while ago, I read in this thread that the daily airshow viewers set out 20-21 meters.
18.7 would make it shorter than the F-22 right?
. Is the J-20's body really that much of an optical illusion, or are the viewers in Chengdu right while the satellite image is just fuzzy...?
@mig, it's not a discrimination against you or anything, but let's be frank, past threads which you've contributed to (especially this one) have been diverted with pages and pages of aerodynamic posts by you and others. There was that (again I say, interesting) aerodynamics thread a few months back where there were dozens and dozens of pages of posts. Preferably they should be in a different thread rather than the main J-20 thread where members and visitors will likely be attracted to. Most will want to see pics and news and information tidbits about J-20 rather than long winded, multiple post spanning analysis and debates on aerodynamics.
Just sayin, imho.
And siege, lol not sure if you're reading the same thread I am, I think no one's taking anything personally

@kyanges, yeah 18.7m is a bit short. Last year I remember calculating (based on J-20 vs truck whose dimensions we acquired) its length to some 20m. And even if we could calculate wing loading that doesn't translate exactly to the plane's real kinematics (the principle i learnt was that an aerodynamic feature doesn't immediately translate into an overall effect without taking into account other factors. And for the aerodynamics of an advanced 5th generation aircraft that should certainly be the case.)
