wow... thats something....

one of the reasons designers dont go for a canard based aircraft is because of the downwash that it creates which leads to decreased efficiency of the main lifting surface...

is it possible to design and put a canard close to the wing's leading edge so as to reduce the downwash from it, in the sense that the wing acts as the canard's downwash inhibitor?

obviously, the canard is computer controlled and hence can be directed appropriately during wing stalls and hence "generate lift". This is very similar to the diagram that i put up earlier, except that i misinterpreted that the downwash from the canard is going to help change the AoA of the main wing and hence maintain lift in the main wing itself. but, now i get it that it is the other way around. That the canard generates the lift at stall and the downwash is not helping the wing at all.

now the question is...

how is that the canard, being such a small surface, able to generate enough lift, even though there is so much drag being generated during wing stall and hence reducing airspeed?

ah... true...

then, in the case of an aircraft having the canard not as an elevator plane,it's purpose is to have a higher AoA than the wing thereby stalling before the wing does and hence bring the nose down eventually bringing the aircraft back to stable flight? or is there more to it? please enlighten me upon this...

thanks....

but in case of eurofighter and many other modern aircraft, the canards do move...

ok, in the case of eurofighter, the canards are way away from the wing, but in the case of sukhoi 30 mki, it is close to the wing's leading edge and the canards do move in both positive and negative angles

apart from the canard stalling before the wing and thereby preventing actual stall, can a canard be thought of as modifying the incoming air stream at high AoA, so that the angle at which the air stream actually meets the leading edge is at a favorable angle?
