Wing vs wall to wall wing,total drag comparation at same AoA? Compare total drag of wall to wall wing vs wing(open tips) in wind tunnel,AT SAME AoA.
My first intuition is that wall to wall wing has higher pressure drag at outward parts of wing,because side-walls &quot;act&quot; as big endplates,so that makes difference.Reslut is higher total drag.
But

•wall to wall wing
If aerodynamic force1 =70N and angle A = 75° Drag1 =cos75 x 70N=18.1N
•wing
Aerodynamic force2 has lower magnitude lets say 60N and reduced effective AoA is 1° ,then angle B=74°  Drag2= cos 74 x 60N =16.5N
(even if I choose 65N(only 7% reduction in aerodynamic force)drag will be smaller at wing ,cos74 x65N=17.9N)
I think Peter Kampf has best opinion,this can not be prove with data because we dont know how much is magnitude of aerodynamic force at wing is reduced compare to wall to wall wing..
Wing has tilted  aerodynamic force back but in same time has lower magnitude ,so it cant be prove is drag higher or lower,it can go in both directions.
Vector tilt back at wing is usualy very small,maybe 1°,so my general oppinion is that vector tilt back has less contribution than reduction of aerodynamic force magnitude at wing...
What is your opinion?
I agree with your conclusion that the wall-to-wall wing has more drag than a free-flying wing at the same angle of attack.
But what is the point of this comparison?
People build wings to create lift. These wings might be on airplanes, but also on helicopters, propellers, the fin keels of boats or the blades in turbo machinery. Their purpose is in all cases to create lift. Not drag. Drag is an accepted price for that lift creation, but not their purpose.
So it is pointless to ask for a drag comparison when disregarding lift at the same time. This is akin to asking if a wing that is not moving creates no drag.
You don't even let us know the wingspan of those hypothetical wings. Are they in the same windtunnel, so the free-flight one has less aspect ratio, span and surface? Or is it the same wing, with the windtunnel removed?
So please stop repeating the same pointless and insufficiently specified question over and over. You will not get useable insights because the answers can not be helpful.
