Improving low speed authority of ailerons? in Flight Design Posted November 20, 2017 Vortex generators improve low speed airflow over the wing enhancing a wings performance in slow flight. A benefit of this is a lower stall speed, but at a much less advertised cost (usually) of less stall warning. Of greater benefit (in my opinion) is that the vortex generators improve the aileron authority deeper into the slow flight regime. I am interested in experimenting with vortex generators only affixed to the outboard section of the wings so as to enhance the low speed authority of the ailerons while leaving the inboard section of wing to stall at it's normal angle of attack. It seems likely that others may already have experimented with this idea and I am wondering if any information is available? I am especially curious if a second row of vortex generators closer to the ailerons has been experimented with and if it has proved to be beneficial or not? Also how far forward of the ailerons would a second row be placed to maximize aileron performance? Thank you.
