It’s not the curvature alone what makes s-duct effective.
No but how much of the Yak-130’s engine lies above the wing? 0%?
Now what’s the answer for the T-50?
Big hint:
5 – канал воздухозаборника (the air intake duct).
…if you don’t believe the patent, a guy who actually works on the plane has confirmed S-ducts. What more do you need?
the simulation have been your main point ,and i pointed out the mistake in it , if it make such big obvious mistake then the accuracy of he other part of the simulation are questionable
actually no ,not all , do you know why ?
because in their graph , they connected the point below 2 Ghz (-10dBsm ) with that 40 dBsm point , instead of the 18 dBsm point,
do you even know how to read a graph ?
Nice try but 200 MHz to 600 MHz isnt L band , and have nothing to do with discussion from the start , the ” ~20dBsm is confirmed in other literature” is about L band , all others simulation posted from start didn’t go bellow 1 Ghz
nice try Sakura , you take a single RCS value at very narrow aspect and tried to claim that is the B-2 RCS at 1 Ghz :highly_amused: ,but you know what funny? if you actually paying attention , the undergraduate study also showed massive RCS from exactly the same aspect , also reached 20 dBsm (aka 100 m2 )
however both design still showed relative small frontal RCS at 1 Ghz
So much blah, blah, blah and not a single answer of any substance. No answers because you don’t have any.
The graphs & charts I read every day are very different to the ones you come across in high school. Btw, speaking of “nice tries” why don’t your squares match further down the x-axis? Hmmm…
Did you even consider for one moment how your beloved ug stealth plane is going to fly, fight and survive with a beam aspect of 100m^2 (20dB) @ 10GHz??! That’s the same as a B-52!! Was that in the RFP too?!:highly_amused:
Amiga, I’ve already tried to explain that to him. He is not to be taken seriously.
