So this pakistaniGuy really think he will end up with more money, if he moved his wallet from the back, to the front pocket.

Some pakistani village is missing it's village idiot.

Is this a 2021 with WS-10B engine modified ?
claimed by ...

Yes. It is a modified WS-10B engine ... nothing really to "claim" here

"CANARDS gives extra surface to the radars"

Hey pakistaniGuy, the engineers at Lockeed Martin, must have made a big mistake, according to your silly theory, because they have designed, a giant flying wing, with wingspan 52.43 m and Wing surface area of 465.5 m².

View attachment 429148

DIMENSIONS:
Length 69.00 ft (21.03 m)
Wingspan 172.00 ft (52.43 m)
Height 17.00 ft (5.18 m)
Wing Area 5,000 ft² (465.5 m²)

With such a giant wing and huge wing surface area, it must be no way stealthy, according to your limited knowledge. I guess, you have never heard of COMPOSITE MATERIALS, and RADAR ABSORBING MATERIAL(RAM) coating to decrease radar signal reflection.

According to some self educated stealth expert living in this forum, the name of the parts is the key point to achieve stealthy, no matter it is big or small.

The two giant stabilizers generate 0.000000000001m^2 RCS, for it's called Stabilizers which is much closer to "stealthy".

They will lost this 0.000000000001m^2 RCS ability when move to front of the aeroplane and named as canards, that's a joke.

Wings, V-tails, H-Tails: good name.
Canards: bad name

Your question is explained: B-2 is stealthy even the wings are much much much bigger than J-20 canards.

Because @pakistanipower doesn't know what he's talking about ... he equates RCS only to surface area ... idiot

For once, I agree with you. If @pakistanipower equates RCS only to surface area, then he's a bigger idiot than I've previously imagined ... . This proves that he doesn't have the slightest clue of how RCS reduction shaping works ...

With respect Mr. @Figaro you add 2 massive CANARDS in the front of main wing and expect that they don't give the extra return for radars including the main wing, what great logic you have Mr. @Figaro

look at your self main wing RCS+ CANARD RCS= one added (CANARDS) for increased radar return
PAKFA's lavcon far more better than J-20 massive CANARDS in the term LO or STEALTH gives far less radar returns

Still need time to tell...let's not try to get ahead of ourself.

It honestly seems kinda dumb of you to bash @Asoka posts when you yourself cannot understand the basics of RCS reduction ... . First, the J-20 has closed coupled canard, which differ from the traditional usage. Then again, they are not perpendicular to the main body ... so conventional rules don't apply. Let's not use the words "huge" ... we don't want to sound like a 5 year old @j-20blackdragon

Sir how can you hide 2 massive CANARD surfaces from radars in front of main wings whatever makes these CANARDS composite materials and RAM, i can't understand it or those CANARDS made of some kind of out of this universe materials that totally invisible/transparent to all electromagnetic waves as @Asoka said

J-10

RAFALE

GRIPEN

AND FORMER MIG-1.44

and J-20

so kindly please explain me that how can its hide excess radar returns with exception of the main wings

Guys could You calm down and esp. Dont use big letters and colours any more. It does not make your claims true.

If you look at several stealth designs including Northrop's navalised ATF proposal and Boeing's concept for its 6. Generation fighter, canards are not a no-go for stealth as some claim.

This is plain wrong.

This is the best we can get from AESA image, can you tell us which are the wings, canards or stabilator?

 

[STRANGER BIRD]

Not Real But Cool

 

[ozranger]

Control surface would only have significantly increased RCS when deflected in big angles.

why everybody is still spreading the canard that canards are bad for stealth？？？？？？

How to make carnards more stealthy？ the same way you deal with the wing,deflect, absorb. there is tons of pictures tell you how it is done. you just donot get the meaning of the white leading edge/trailing edge

Control surface would only have significantly increased RCS when deflected in big angles.

yes

when those control surface in a big angle, basically the aircraft is taking off/landing，or dog fighting. radar stealth is not that important in such situation.

 

[Deino]

Can we stick to the topic please? Some are more obsessed to their opinion even if it contradicts reality and we are now so much in general aerodynamics.
