Then he and Joe must be enjoying themselves...
Corvettes were very difficult to measure, especially at ground level.
As was already mentioned, the F-22 all-moving tailplanes have a similar stealth impact as the J-20 canards. The J-20 does not have tailplanes. However, canards arguably have a greater effect on stealth because they are more actively maneuvered in the absence of thrust vectoring. At this time, I believe it is a minor tradeoff to achieve superior maneuverability vs a relatively insignificant stealth impact. However, if the J-20 is to ever be fitted with thrust vectoring, the combination of canards will give it unbeatable agility.
Actually, the J-20 5th generation fighter has canards.
This is not to say that the J-20 should not have thrust vectoring as this would give it clearly superior maneuverability over thrust vectoring only aircraft.
I heard they are pretty tough rigs.Unimog
a bit easier to measure than corvettes, not to mention corvettes are a bit rare in Greece.
This is where you are mistaken. No one is denying that the F-22's rear horizontal stabs are EM generators. Yes, they are. But their diffracted signals are off into free space, not onto the fuselage or onto the wings as in the case of the J-20. This is where it gets problematic. Interactions means two possible events: Destructive interference (good) or Constructive interference (bad). The diffracted signals from the canards will interact with the diffracted signals off the fuselage and the wings. We do not know the results of those interactions.
I think most people understand that components can sometimes have secondary benefits besides their primary function. Ventral fins that also block most of the lateral heat signature from the nozzles that are not already attenuated by the LOAN technology is an added bonus wouldn't you agree?...On one ground u are saying j20 engine are based on LOAN technology & another hand u r saying the ventral fins shield the jet engines from lateral view and contribute to lateral infrared stealth then what's the use ventral fins then tell me . Do u think it can protect the plane from 5th gen HEAT seeking missiles like python 5 absolutely
no you told it blends from side profile but what from behind & below ?It would be surely detected by anti stealth very low frequency radar most probably ground based radars (X band 8 to 12 GHz)from below and aesa radar from behind
so again a big LOL for u
Good point. I cannot comment without a supercomputer on hand but if I were to take a wild guess, I would say the continuous curvature as implemented on the canards would be shaped to diffract any EM outwards away from the fuselage from the frontal aspect. However, avoiding the wings is a problem. In real world situations, the canards should be kept in alignment most times except in dogfights or once detected. I would not be surprised if there were different flight modes available for this very reason.
Not sure this is correct. I'm not talking about laterally or from above or below like the YF-23. I asked if there are any fighters that hide their engine heat signature from the BACK...as in if you are looking into the exhaust, which as I said would be a pretty good trick.
And I see that you felled for that 'continuous curvature' thingie. Your guess is as wild as it is wrong. In order to have diffracted signals away from the fuselage, the TRAILING EDGE of the canard must be angled 'away' from the fuselage. Continuous curvature has nothing, or at best very little, to do with this. Am sure you can find plenty of publicly available images of the J-20 to see for yourself the angle of those trailing edges.
