Stall control with feathers : self-activated flaps on finite wings at low Reynolds numbers
We present experimental data on the use of a “pop-up feather” type high lift device (passive flap) on the upper side of the wing. While a number of previous studies have shown the effectiveness of this flap in two-dimensional geometries, we focus here on the use of the flap on finite wings and th...

| description | We present experimental data on the use of a “pop-up feather” type high lift device
(passive flap) on the upper side of the wing. While a number of previous studies have
shown the effectiveness of this flap in two-dimensional geometries, we focus here on
the use of the flap on finite wings and the three-dimensional flows involved in these
geometries. We present parameter studies to determine the optimal size and location of
such a flap on a rectangular SD8020 finite wing. We show that the flap has virtually no
effect on the wing tip and that the optimal placement of the flap near the wing root is
close to the optimum found in two-dimensional airfoil studies. |
