I thought the fundamental difference between a symetric and asymetric wing section was the polar curve shifting upwards with the Alpha 0= angle of attack for zero lift, going negative.
In the range of AoA relevant for A-Cat boards, the lift curve is linear.
With asymetric, you can probably (to...
Thanks for the explanation, but I am afraid I am not a good pupil, I struggle to understand in depth
So far what I understand is: by lifting the windward board you remove the frictional drag
of course if it is no more in the water ...
But when it comes to:
in the board windward that...
Very interesting ,
Please forgive ma ignorance, what does that mean:
"Almost completly removing the friction due to the asymetry" ?
Do you use OpenFoam to design your foils ? or other software ?
Thanks in advance for your kind comments ITA 16
