1. The J-20 Mighty Dragon does not need a saw-tooth design at the rear of the canard, because the J-20 canard is made of composite material, shaped to deflect radar away from transmitter, RAM-coated (which Rafale lacks),
LOLLLZ , really martian ur stupidity is unrivalled in this planet thats for sure
1)composites: Do u have x ray in ur eyes?? then how do u know it is made entirely of composites ,BTW rafale also has composites compare but not entirely .
2)RAM coating : what rafale canards doesnt have ram coating LOLLZ . Is it mandatory that all ram coating should be black like
j20 .??? then F22 also doent have ram coating lollz
1st of all understand the basics of stealth or order of importance of stealth in a plane
1st.comes shaping of plane ( Angled or canted surface/ saw tooth pattern ) , then comes composition of air frame (composites) , then at the last comes surface coating (ram coating) .
because composites & RAM coating doesnt guarantee stealth always as RAM properties is unreliable at all radar frequencies .The most important part is shaping .
now see the importance of SAW TOOTH pattern in rafale's canards , i hope u could understand from the pic the importance of
saw tooth in stealthiness of rafale's canards as compare to J20 canards
the canard-fuselage intersection is specifically designed to deflect radar. In conclusion, the J-20 canard is very stealthy.
The claim that the J-20 canard gap is a corner reflector is not true. Go ahead and try to draw a ray trace diagram to show a corner reflector. You cannot. It is a surface discontinuity as a tiny radar source. This kind of surface discontinuity is also seen in the T-50/Pak-Fa's airfoil gap and main wing control surfaces for the F-22, J-20, and T-50/Pak-Fa.
Tell u what man ... J20 's canard-fuselage intersection is a stealth disaster as it's junction has rounded protusion
which allows the radar waves enter into that J20 gap & bounce back to it's radar source .Not only through gap but from below
also the radar waves can hit the surface round protusion on it's canard & fuselarge junction. This rounded canard-fuselage protusion gives a source of tiny corner reflector for J-20's canard gap. It is not found in rafale as usual clearly justifying my point that rafale's canards are much beter in stealth design than canards
OMG (facepalm) what u compared "surface discontinuity in the T-50/Pak-Fa's airfoil gap as corner reflector surface??? lolllz
U forgot pakfa doent have any rounded surface protusion in it's wings & fuselarge junction like J20
now see the pics u would understand what i mean
2. J-20 slightly-rounded LERX is a minor criticism. It can be easily fixed. It is trivial.
Lollz It is minor criticism as u urself claim round surface are big No for stealth as in PAKFA IRST as it round .
as any round edge or surface may reflect some amount of radar waves back to it's source
Radar cross-section - Wikipedia, the free encyclopedia
3. The third point about the angle of the J-20's wings is without merit. I have already written a post to compare the planform alignment of the J-20, F-22, and T-50/Pak-Fa. It is silly to argue for more planform alignment angles on the J-20.
The shape of the main wings is designed to match the aerodynamics of an aircraft. The J-20 has canards and its wing shape is the most appropriate aerodynamically for the aircraft. The guiding design principle is "form follows function" and not why don't you copy design features from other planes.
blah ...
i am comparing the edges of all the 5th generation plane as it should be & J20 clearly has less edges & less angular as compare to all 5th gen fighters which is due to it's vintage design features like DELTA wing, Rounded lerx & CANARDS which clearly raises question mark on its effectiveness on stealth ground
.
Off-topic: Nice try Mr. Somnath. However, this nit-picking won't work. You need to find a major flaw to grab people's attention. The only major flaw on the J-20 is the round engine nozzles. The J-20 engine nozzles are serrated like the F-35, but they are clearly not as stealthy (in both radar and infrared wavelengths) as the F-22.
LLOLLZ martian i had proved my case clearly but u turndown all my critiscism as minor .Meanwhile u can find all flaws in pakfa as major including Rounded IRST. This shows what double standard u have .
what J20 engine NOZZLES are serrated Seriously ???? ,have u ever compare F35 nozzles with J20 nozzles in ur life time
Mr. Somnath picked a terrible example in the French Rafale when he attempted to illustrate a perceived deficiency in the J-20 Mighty Dragon canard design. The French Rafale is not to be emulated in any way in the design of a 5th generation stealth fighter. The round shielding to hide the canard gap is far less stealthy than the J-20 canard's elegant back-end to deflect radar.
OMG (facepalm).!!!!
as usual martian time & again u have proved ur unrivalled stupidity in this planet ,nothing cant be the greatest example like
u have done here .HEY man i had compared only the stealth of rafale's canard with J20's canards which clearly is more stealthy as shown by me above .But god damn it u compare entire 4.5 gen rafale plane with a 5th gen J20 plane ..Hey man even a new born baby knows rafale is unstealthy compare to any 5th gen plane .This shows the height of stupidity u have attained today in the entire foruming history of yours .
Not only that u have posted a trash pic containing many wrong information about rafale's stealth .U r simply a great J%%K%$$
Anyway, I'm off. If Dr. Somnath shoves another "J-20 sucks" post in my face, I'll be back.
LOLLLZ martian perhaps u have said one thing right in ur entire lifetime about J20 .This is the reality yes it does but in terms of stealth
