Hi all
i am investigating?!? the low reynold's number high lift airfoils section for a wing sail to be used on a C Class catamaran
the wing would work on a range of Rn from 600.000 to 2.000.000
and at angles varying from 0 to about 10-12°
the area is 28 m2 nd should provide a range of maximum lift between 170Kg (upwind course) to 250 Kg (ownwind course)
the only limit i see at the moment are the maximum span fixed at 12m and the fact that for reason of lightness i should avoide high torsional loads on the main element from the flap
i believe that a 30% flap could be tolerated
section involved E421 and E 423
thanks in advance for the collaboration
best regards
Marco
